Loven Amsoil

So fare so good, I put amsoil in my 2016 Subaru impreza and she runs like a champ just like my 06 Chevy Silverado.

I have been running amsoil in my 06 Chevy Silverado for a few years now and I have seen the benefits both in overall preformance and reliablilty, it has transformed from a ticking tapping noisy engine to a quiet and smooth running one, you can't even tell it's running most days, the truck only has 100,806 miles on it but I wouldn't put any other oil in it, as soon as I try it start the lifter tapping thing again it is kind of weird in my opinion so I think its safe to say that this truck likes its amsoil.
But i thought to my self why not put it in mysubie and get the same benefits as the truck. Both vehicles have amsoil in ever oil driven/gear driven component and I am a believe in amsoil. I am think about trying it I'm my lawn mower this summer and in my snow blower this coming winter. Why not lol

Great oil for my race car

Run this oil in my 2002 corvette road race car. Dry sump engine, need the best protection. Great oil and has not let me down! Thanks Amsoil!

Would by again

This oil exceededs my expectations by far. Before using this oil I would always have a faint ticking noise in my valve train. After using this oil it is so quiet i couldnt belive it. The oil life itslefs last an incredibly amount of time as well. One of my favorite things about amsoil ut leaves behind a small film of oil after u shut down your engine. So when u start back up it still has a small flim to protect your engine intell the oil is pumped up. I use amsoil in ever one of my vehicles

Never Compromise

I trust this oil and the other Amsoil products because they work. I know that the maximum vehicle life and best operating effectiveness come from due diligence in maintaining it properly. There is great comfort in knowing I didn't compromise with the products I used. Keep rolling!

Love This Product

Have been using this product for about 9 years on both new and used vehicles. With extended mileage, I only change 1X per year. Cars have performed flawlessly.

Ultimate Protection

Our Subaru hemorrhaged out all of it's oil on a trip (16 miles) to our Mechanic. He later called us and asked what type of oil we used. When I told him Amsoil Signature Series, he said "keep using it; you were totally out of oil !!". Using it for 20 years now. Never had an oil related failure.

Only Amsoil For Me

I use Amsoil in all of my vehicles (4) and I believe that's why they perform and last a long time!!!

I will continue to buy this product

I have used this product in my 2009 Civic since it was new. Now with 195000 miles It has never been in the shop except for tires and brakes and 100000 mile spark plug change. It still runs like it did when it was new.

Great product

The SS 0W-20 works awesome! I just wish it were a little cheaper in price, even with the PC, it is still a little bit high in my opinion. However, it is a great 100% synthetic oil. My 2015 Silverado with the 5.3 V8 runs a lot smoother and has more power with this SS oil in my opinion.

It doesn't get any better!

I've been an Amsoil PC for around 10 years now. I love Amsoil products and so do all my machines! There is no better value for your money. I have never had any engine problems in anything I have poured this liquid gold into. My wife's 2013 Toyota Rav4 loves it!

I use this product in all of my highway & mountain vehicles

I use Amsoil in all of my vehicles as recommended. We just handed down a 2003 Toyota Matrix with over 200,000 miles on it to our Granddaughter. This car was still of high quality even though it was used daily on dusty and dirty farm roads; as well as highway. I hope she gets another 100,000 miles or more.

5- 20

Have used this oil on two of my trucks one has over250000 miles and still going strong. Love this oil,use it in my motorcycle too.

I would buy this product again

I use it in my car and when I change oil it still has a great consistency

The Best

This oil I use in our 16 Escape, to better protect it's turbo. Living in Wisconsin it can be well below zero in the winter, and what a difference Amsoil synthetic oil makes.

Only the best

Nothing but good to say about amsoil products.... they are the best!

Hi quality oil

I'm finding this oil looks cleaner and it's viscosity appears to hold up longer than Mobil 1 after the same 10k miles. I will continue to use this oil in my 2016 Mustang GT. 52k miles already and still running strong.

Great oil

I run this oil in my 79 Chevy k10 and change it once a year with a fresh oil filter mid year my speedometer doesn't work so I don't have to worry about changing the oil every 3 months I am really pleased with this product

Great Products

I have been using these products for more almost 30 years. I trust them.

Great product, loyal user

I have been using Amsoil for at least ten (10) years, it's a life, and engine saver!

Been using signature series for almost 2 decades

I've used the Signature Series oil in everything from a well-modified 99 Neon that routinely saw 8k rpm to my wife's turbocharged Ford Transit that takes our kids everywhere, and it's never let us down. I would conservatively put the amount of mileage we have on this oil over the last 20 years at 350k miles, and that's a lot of saved money in oil changes by using Amsoil's extended change intervals. I've never had a problem with any engine having oil loss issues, either, no matter how hard I ran the motor.

My absolute favorite oil!

Works great in my wife's Buick Verano. I also use the 5-30 and 10-30 signature series in our GM pickups. My 2003 Silverado has 293,400 miles and doesn't burn a drop of oil! Bought it with 90k on it and has had all Amsoil fluids in it ever since.

Great product for any Chevy LS

This oil works great with E85... Best I have found from the major brands.

Amsoil is some Good Stuff

I used to be very sceptical of synthetic oil so I decided to try it in my company truck(not my company). The truck ran up 200,000 miles and still running strong with minimal oil consumpsion. My wife has a growing cleaning business and I do the maintenance on the cars. Using Amsoil I went from 5,000 mile changes to 15,000 miles using the Signature Series 5W-30.
She now has fifteen cars in her fleet, that cuts my oil changes from forty five to fifteen, that is a tremendous labor savings for me and it actually saves money. I use Amsoil in all my vehicles now and it keeps them running strong. I recommend to anyone that asks that they need to try it out. Great Product

This is the only product I will use in any of my vehicles

When I buy any vehicle, I change to Amsoil Signature Series the first oil change and use nothing else thereafter. As a volunteer fireman, my vehicles are subject to being run at high speed while cold. Signature Series provides outstanding protection. Some have over 200,000 miles on them and none use oil.

I want the best

Modern GDI engines require excellent oil to stay clean and handle everyday extremes. If you are using your cars maintenance indicator you might be exceeding other oils capabilities I know signature series gives me the best I can get

The Best Protection Money Can Buy

I run this Signature Series 5w-30 in nearly all my vehicles. Typically I see a 10% increase in gas mileage ( over an engine ran on conventional mineral oils ) on the interstate no matter what size engine. In one recent event, I blew a head gasket on a Quad 4 engine yet drove the car for about 10 miles. Observing the chocolate milk colored oil, the engine was not damaged as it was protected by Amsoil Signature Series lubricant.

The best cost more

Yes Amsoil oils are more costly that many
other oils. I keep my vehicles for decades
and want the best oil protection I can get.

Only the Best for my Engines

I use amsoil don all my vehicles

Best on the market

I have used only Amsoil in my 2005 Toyota pickup.
I now have 205000 miles. I have never had a problem
and still us no oil and have no oil leaks.
Change every 25000 miles.

Amsoil

Hi. I am totally sold on Amsoil ! Superb protection. Awesome lubrication. Even in a little engine overheating, it still protects ! I reccomend it to the world ! Nothing beats it ! Nothing !

I will continue to use Amsoil

I can't think of anything negative to say

Yes

In my personal auto's

I will buy this product again and again

Made the engine run so quiet

I haven't found a better oil than amsoil signature series

I don't remember how I got started with amsoil oil. I use it in all my motors. The 5w 30 is the one I use in my 2003 Chevy pickup. It was making a loud ticking noise before I started using amsoil in it. As soon as I started using it I could tell a noticeable difference and smoothness and the ticking went away so I'm very happy.

I would by again

Best oil on the market.

It's the best choice for your engine!

It goes in my 3.6VVT and my 5.4 2V and does wonders for engine noise, oil change intervals, and most of all performance! It doesn't matter if it's a modern engine or not so modern engine, it Works!

Best synthetic available

You can put any oil in a new engine and call it good. I run my cars 200k+ that's when oil matters. Amsoil cools,cleans, seals and lubricates better than anything I have used and I have tried them all.

Best oil, no competition

I drive for work 1,000 miles plus a week, I use Amsoil in my car along with my wife's... I have right at 300,000 on a 2012 Kia Soul and the motor is just as good and clean as the day I purchased. I save money as well... using any other other brand is crazy

Very good product!!!

It's the best hands down! Some people think it's all the same ! There wrong! 25,000 miles you can not bet it.

The best oil on the market

I have used AmsOil exclusively for over 20 years. It's the best there is. My truck loves it.

I plan to continue using

I use in my 1999 Corvette because I like to use the best, and also in my 2016 Dodge pickup.

I would buy again

I use this every 5k miles. The car runs smoother and quiter than my previous oil changes. It doesn't lose it's slickness. I'm overall satisfied with this oil.

yes, i have been using AMSOIL sence 1985

cars' trucks' & motorcycle, lawn mower, snow blower

Best oil i have ever used

This is the best oil I have ever used in my Ram 1500.

Worth every penny

First thing I noticed right away was how it make an already smooth engine even smoother and quieter. I've always used Mobil 1 advanced 15k oil and have heard nothing but great things about Amsoil. A co worker of mine had a teacher in tech school who used to rebuild his engine every year after racing season. He switched to Amsoil and hasn't had to rebuild it in 5 years. As soon as I heard that I was sold. If you want the best Amsoil is it.

No problems

I have been using this product since vehicle was new and have had no issues with my vehicle. Engine runs great and strong and I change about every 15K vice 25K as put a lot of miles on this vehicle.

Always use

I love this brand of oil and been using it for the past yr on mustang.

Peace of mind

I have used this oil on my cars, trucks, and sedans. Never balk at the cost, knowing darn well I'm getting what I pay for. Less oil changes, frees up time, less waste, and superior protection.

Great oil

Last truck had 175K and never used a drop of oil. Change oil, run 15-20K and still full.

Smooth Operation

After breaking in our two new 2017 Mustang GTs, performed oil/filter changes on both. The two things I noticed was quieter engine operations and a small increase in oil pressure. The engines also ran smoother than before. Overall, I'm very satisfied with the notable differences I've experienced.

The Good Stuff

Best Around enough said

The oil to use for vehicles you plan to keep

I have been using this oil in my 02 siverado and 02 suburban since 04. 297k on the truck and 317k on the sub. Oil is changed once per year, have had 32k in one year on the truck. Engines still run great and have no oil consumption, increased fuel mileage seen on both. I don't use anything else

I really like it

I used this on my 2002 Tahoe the oil at 3000 miles looks like new yet. In the very cold weather here in ND it start right up. Vary pleased with oil. I will be doing all the fluids in my Tahoe with Amsoil.

Only

Unless I can't afford it Amsoil will be the only oil I use. It is very good and while some people say it is more expensive, they are usually comparing it to cheap oil, it is worth every penny.
Considering the extended service length it is great.

Great oil, maybe the best you can buy

Been using this oil for several years now and get great results from it

Beyond expectations!

Been using Amsoil for decades, in everything I drive. Have over 2 million miles in a Semi with Amsoil. Increased life of every component . I pushed it to the limit , never failed. And I push hard ....

I would recommend using Amsoil

I like taking care of my cars that's why I use Amsiol

Best Bang for your Buck

I've been using Amsoil since 1998. I've had to replace the intake manifold gasket on past pickups, when the mechanic ask me if I cleaned the inside of the engine before bringing it in I said no, I use Amsoil full synthetic. He said well the inside of the engine had absolutely no carbon buildup. He said that was the cleanest engine he had ever seen that had 110,000 miles on it. From that day forward he too was a Amsoil customer.

So far so good

I drive a 2009 HHR with a 2.0 NA 4 cylinder engine approx. 100 miles a day and have 160,000 plus for mileage. Economy comes in many forms in this case fuel, oil and tires are my biggest expenses and ones that I can somewhat control. We had a cold spell not to long ago of real temps -25 and colder. The HHR still has the original battery and with the Signature Series 5w/30 it cranked right up with out a problem. Next step is to submit an oil sample same time as the factory algorithm says to change oil.

When you are the best the hech with the rest.

The wear scar test results verify my faith in your products. combined with the best chemical package to keep my three Diesels & 2 Gasoline motors clean. I like the 25,000 mile products, saves time. thanks for the extra engineering it took for development of these products.

Best oil on the Planet !

Actually get better fuel mileage , performance and reliability from using Amsoil . Why not use the best in these expensive vehicular .

Non deceptive Hi quality products

Your products are easier to compare because the specific facts are up front and easy to understand and are a great value.

Great Oil

I use Amsoil in all my vehicles and equipment. I would recommend it to anyone.

2009 Ford F150

The truck runs great and uses no oil at 130,000 miles

A++ lubricant

This oil does what they claim it can do. I normally try to change my oil at around 12000 miles, but sometimes if I'm too busy it goes much longer. At the last oil change, I changed it at 25000 miles. No problems whatsoever. The dipstick oil level was still normal after a year of use. The Signature series oils are worth the extra money. I also use the diesel oil in my 06 Duramax truck. It's about to hit 400,000 miles and not a single problem.

Amazing

Now this may sound negative but it's a positive. I bought the 10W 30 for my 1998 Jeep TJ 2.5 with 250,000 miles on it. Amzoil really cleaned and lubricated my engine really well. I dont recommend going to a synthetic motor oil if you have high milage and you did not you synthetic oil prior to because this oil cleaned my engine up but I developed a leak. But in retrospect I'm am going to use only Amzoil in it when I rebuild the engine. Went back to Dyno oil for the time being.

I don't anything else

have used Amsoil for the last 15 yrs. never any complaint with it the only way I get my lawn tractor with the snowblower started in the winter starts every time

Love this oil!

Using this oil in 1950 Chevy truck with 2004 LR4 4.8L engine. Starts and protects from below freezing to 90+ in summer with constant oil pressure. Engine looks new inside.

This is the only product I use in My vehicles.

I have changed both vehicles over to Amsoil in the engines and the differentials,transfer case and transmission on My pickup and will soon put in Amsoil coolant.

Nothing but the best

As far as I am concerned Amsoil is simply the best for all of their products

Amsoil fluids

I have used Amsoil 0w 30 in my 1998 Corvette and now I have 213000 miles on it and there are no unusual engine noises. I change my oil once a year. I have three boats 2 Corvettes,1SUV and a motorcycle all use Amsoil products. I virtually have had no powertrain problems. I use nothing but Amsoil and will continue to do so. I appreciate Amsoil technical papers as they show the science behind these outstanding fluids and are useful to convince others of the merits of Amsoil.

Best engine oil, period.

Excellent product and protection. After doing much research will only buy this product to protect my classic sports car, and daily driver.

Amazing oil

Long life. Engine oil stays clean.

Never a regret

I have been using Amsoil in my vehicles since 1986. After having to change a timing chain in an earlier vehicle...it was clear ( internally ) how good Amsoil actually is. The chaincase was as clean as if it was just made. That vehicle continued on to + 260,000km with no oil leaks or other loss.
Amsoil....I am a fan for life!

Best oil

I love all AMSOIL products

Best oil you me or anyone else can buy.

I use Amsoil in all my vehicles, and I have many. From my Shelby GT 500 to my ATV and lawn mower. Best oil you can buy!

The Best Oil

Been using Amsoil Signature Series 5w20 for over 18 years and have been extremely happy with it. I go 15000 miles between changes and never use more than a half quart between changes. It's the BEST.

Always satisfied with Amsoil

I use this in both of my vehicles; one specs 5W-20, the other 0W-20. It gets down to -15 degrees where I live in upstate NY and I depend on Amsoil to provide effective lubrication at temperatures where other oils struggle to perform. I generally put over 250,000 miles on each vehicle, and have never had one consume any Amsoil. Totally satisfied.

Best oil period

I have to use the best oil. The cost of not using Amsoil will put me out of business

nothing but this

I've used this oil in my vehicles for at least 10 years and they have performed as promised.....also haven't had any leaks from the engine ....wouldn't change!

Best oil on the market

This is by far, the best product on the market.

Best Oil Ever

I do 10k mile oil changes per Toyota, but this oil comes out still clean, not even black. I have no doubt I could use it up to 25k miles.

100% trust in all Amsoil products

Every oil change gets Amsoil

Engine started when -34F

My 16.5 year old truck still started in the cold Iowa winter when plenty of other vehicles even newer ones wouldn't. Have to give credit to good synthetic oil.

Best money can buy.

Extended drain intervals, combined with my bypass filter, I'd drive this thing to the moon if I could figure out how to get it off the ground!!

Good fuel mileage

Good cold weather starts

Feel the power

made a grate difference engine is quiet with a 10% better on gas can't wait for my next oil change

Yes I would buy this product again and again

I've used this product on my 2014 Jeep Wrangler, I love this oil been using it awhile with no issues what ever

10/10

07 FJ cruiser with 150k miles, as soon as I dropped this stuff in, lifter rattle was gone

Good for me

Hard To start very cold day

Oil lubrication

I use Amsoil oil, and fluids in all of my seven vehicles, from bumper to bumper, witch has cut way down on repair, down time and oil consumption..

My Oil

This oil really makes me feel safe knowing the protection it gives!

100% synthetic all the way

Best form of lubrication for any automobile in my opinion.

Only prd

Only product for my cars.

The only oil I trust

I use this in my Ram Rebel 1500 and it keeps the truck running smooth.

I have been using this product for over 15 years

I live a very cold climate. Temps sometimes get down to -30F with wind chils to -50 or more. My vehicles sit out side all year.
I've never had a problem starting them, no mater the temp.

Nothing but the Best for my Rides

I use AMSOIL signature series in my new Ford F-150 because the protection is great, the change intervals can be extended if necessary without lubrication properties breaking down. It conveniently shows up at my door via free shipping as a preferred customer.

10+ Year Customer -

This is my first round of 0W-20 Signature Series for a 2015 Suburban as well as a 2016 Toyota. Paired with AMSOIL EA Filters, I trust the recommendations of the vendor. I've never had an issue whatsoever. Oil consumption using Signature Series 5W-30 on previous vehicles with over of 180K and 207K miles was ZERO. I loved the cold weather start and 1x/year oil changes (avg 17K miles/year).

I won't buy anything else

5W20 is for my 2010 Ford Ranger. I run it hard, and the oil does it's job flawlessly. I use AMSOIL on all 5 of my vehicles. I won't buy anything else but AMSOIL.

Keeps my '98 Subaru and my customers' generators happy

I use Signature Series 5W-30 in my '98 Subaru (138,000 miles), and it couldn't be happier.

Dedicated User

Amsoil got my business in 1983 when we were running two stroke outboard engines at very high RPM's in a racing format. After one season putting the engine through these conditions we would rebuild the engine. After the year was up the cylinders still had the hone polishing marks visible to the eye on the cylinders. Every gas or diesel engine I have owned since that day runs on Amsoil and only Amsoil. Why would I try anything else. The extended run time only makes it a better product as far as price. You can get this quality at or near the same price as just oil.

Works great in every thing

I have been using this amsoil in my Jeep JK 2017 since new, and it seems to be preforming well I also have it in front and rear differential.

Won't use anything but AMSOIL!

Have been using AMSOIL products 4 more than 20yrs. No bone 2 pick. No vehicle I've owned has used oil, excellent performance. Engines, transmissions, manual & automatics, & live drive axles! No problems ever! I will only use AMSIOL! THANX ABUNCH AMSIOL!

Great product

I have been using high mileage synthetic oil for the last 5 years. When i got my emission chech the technician was confused, he said , ' the engine is running so clean, its like purifying the air' !

I would buy this product again.

I have used this product for 16 years with excellent results. (All around good oil analysis, much lower cost, time saved.) I recommend this oil whenever possible.

20 year user.

Great as usual.

Sig series 5w30

I have used this in a few autos as well as a 4 cycle toro, superb engine protection, second to none cold weather starting as well as lower operating temps in the hottest days of summer. Very highly recommended! !

Liquid Gold

This Amsoil Signature Series engine oil is the best I've used.
I call it my liquid Gold. I would highly recommend it.

Best oil available

My Ranger has 210,300 miles. All original engine except fuel pump. Runs great. Amsoil in engine and tranny since purchase.

Great oil, great service!

I like to keep my car in tip top shape, so I use amsoil.

Best product I have found..

A friend of mine has been using this oil for many years and finally talked me into trying it, I have always used synthetic oil but decided to give this one a try, love it..

Signature oil use in 06 vette and 10 GMC 1500

Used for years #1

The best oil on the market

Amsoil Signature oil is the very best oil on the market and I use it in all of my vehicles.

Life time user

This is another product I've been using since it's introduction paired with the EA filters. They make a great combination for protection

Excellent oil

I have been running this oil in my Silverado and my Chevy SS and this is by far the best oil you can use. Now I still change my oil based upon the intervals the car tells me but the protection you get can't be beat. My oil analysis have come back excellent!

Great Oil

Use this in my 2016 Chevy SS, and in my wife's Ecoboost Flex. It minimizes oil use and improves mileage. Was using Mobil 1, switched to Amsoil (after free dealer oil changes ran out) and oil stays clean longer and mileage improved about .5 mpg in both cars. This is year over year, not tank to tank... Both cars rarely see the highway nowadays (both wife and I switched to jobs close to home so side streets to and from work it is)...mpg's going from 14 to 14.5 doesn't sound like much, but it is something!

The best

I bought a n oil change for a friendgreat product

9k miles so far so good..

Best oil I have used so far. 9k miles on it and oil is still good.

Outstanding product.

I used the Signature Series oil on my 1992 Land Curiser with a 3FE inline 6 cylinder motor with 230,000 miles; I replaced the oil filter as well.

The new Amsoil oil change noticeably fixed several issues I was having with this old motor. The oil pressure stabilized, compression, temperature, noise, and gas mileage all improved as well. No more leaking head gasket seals, burning oil, and more throttle response.

Well worth the money!

Feel better engine performance,also the mix of higher octane of gas helps also,love that it limits me to one oil change per year depending on more driving or less.

No one makes better

Amsoil is the only oil company that I've ever been able to provide 3rd party testing documentation against other synthetic oils back when no other synthetic manufacturer would provide that sort of information. I switched from Royal Purple to Amsoil when my father recommended them. I asked them to provide documentation that they were the superior product and I would switch. They did and I've been a loyal customer for over a decade now.

I drive all of my vehicles I've owned hard. I feel they are made to be driven, so I drive them hard and push them simply for the joy of driving. If I am going to purchase a sports car, I plan on driving it like one. I use Amsoil to make certain the internal parts of that engine have the best protection I can give them all year around. I have never had an internal part failure on any vehicle I have ever had due to lubrication failure. I trust no other oil to be in any vehicle I own, and I push my friends and family to do the same.

The only thing I use.

Bought to use in a 2018 Honda Accord 2.0 turbo as the stock oil was burning up and leaving black soot all over the back of my car. The amsoil doesn't do that and now I feel confident about my car not blowing up from lack of lubrication and costing me a ton on money to fix. Just wish they sold it in a 5 quart jug cause having to buy a gallon and then a separate jug is a pain and the individual quarts aren't cheap.

Love this stuff

This Oil is Great. Always Recommend this to others.

I'm convinced!!

Finally tried Amsoil. I put it in my 2013 Cadillac and noticed an instant difference. Smoother idle. Smoother acceleration. Increase in fuel mileage. I will be using Amsoil from now on in all vehicles.

Best oil ever used.

I changed to Amsoil in 2014.I had a new Chevy truck and by changing to Amsoil 0-20 increased MPG by 1.5 per gallon. It worked great for 75,000 miles. Traded trucks for a 2017 Chevy and changed with Amsoil the first oil change. Just great oil. I also use Amsoil 20-50 in my Harley Davidson which runs cooler than any other oil that I have tried. I run the 20-50 Amsoil dirt bike oil in my 2015 YZ250FX works great. I recommend Amsoil to all my friends. Amsoil has never let me down.

I would buy this product again

I use Amsoil in all my vehicles, 2015 Ford Explorer, 2005 F250 super duty, 2016 GL1800 Goldwing, & 2008 Ford Taurus, It's a super high grrade of oil and I had a 1996 Chevrolet truck 5.7L that i had over 250,000 miles and had pulled the valve covers and it looked as clean as if I had just rebuilt the engine !

Best protection and long drain oil

Been using and oil puducts for years it's by far the best lubricant in the industry!

Absolute Best

You cannot find a better oil in America than Amsoil. Read the test data and all the reviews. I was always taught to do research on products to find the best. Thats what I did. AMSOIL is the best!

Amsoil

I have been using AMSOIL Oil for a number of years. I have 340,600 miles on a 2003 SVT Focus and have been very pleased with how AMSOIL OIL has protected the engine.

Signature Series 5w-30

I have been using amsoil 5w-30 on my 2004 range rover hse and 2008 range rover hse for almost 15 yrs now and these oil brings back old cars back to life instantly from fuel efficiency to engine fluidity. Engine feels like new. I change oil from 6-8 months or 7500 miles.

Great oil

Love the performance of my motorcycles w this oil.

Great product

Used signature 10-30 synthetic in my 2002 sequoia and drove almost 15,000 miles before changing the oil and filter. I sent a sample of the waste oil to a lab for analysis. The oil was good, still usable, with no traces of problems.

Does oil get dirty near changing time?

I put OW-20 in for the 10,000 mile coverage. I am 2,000 away from a change. I checked the dipstick today and the oil was black. This suprised me a bit. Is this normal?

Best oil for gasoline engine.

I've been using Amsoil for almost 20 years, my 1999 GMC Yukon Denali, 219,000 miles, and 2008 Mitsubishi Outlander SE, 221,000 miles using 0w30 Signature Series and both still going strong, and now a 2016 GMC Canyon Diesel truck using the 5w30 European Formula, Highly Reliable Product in my book.

Oil Change

I use Amsoil in all of my vehicles. I have found it saves fuel and makes my engines run much smoother and cooler. I have proved the use to many friends with my Harley's showing them how ell they perform also.

This is the only oil I would use again

Motor run smoother get better gas mileage and change the oil less Oil still looks great when it comes out

Preaching to the choir

Have been using Amsoil everywhere possible, don't have to ask twice.

Facts are facts. It is simply superior oil.

The third party tests only depict the facts. But I have many years and many vehicles that only used Amsoil. I appreciate that Amsoil offers OEM and other options. That's awesome. But I've always gone with the Signature Series oils. I keep things as simple as I can. I don't want anything but the best, and I don't want to have to second guess engine protection. A full year (repeated years, one is a 13 yo Focus I bought new), that has never been more than a half a quart below full at its annual oil change. ??? Why scrimp on protection when I'm saving money and producing much less recycle oil, AND the car runs awesome after all these years?

The best oil and filter out there!

I switched from conventional oils and filters back in 2012 and its been the best decision I've made concerning lubricants.

Top Tier Oil

I have used this since the first oil change in my car that I bought new in 2016. Newer vehicles call for a 0W-20 oil. With that thinner weight oil I am concerned about wear protection. Looking at independent test lab results of Amsoil 0W-20 oil I see that it does better than other oils and passes the tests with ease. My car also has variable valve timing which can be vulnerable to sludge buildup. A clean synthetic oil is a must and the Amsoil additive package fights sludge better than others. We get easier cold weather starts and slightly better mpg too. Spendy but good.

Excellent

I believe that Amsoil is the best motor oil that you can buy.

The only oil I use

Keeps my Subaru DIT engine running smooth. I wouldn't put anything else into a turbo charged engine.

Perfect

Great product

Good oil

Oil seems to work very well . This is the second oil change with it - so we'll see how it goes from here

Amsoil

I have used Amsoil forever. I dont trust any other oil in my vehicles.

I will definitely buy this product again!

I really have enjoyed the switch to synthetic, I was super pumped to open up my kit in the mail.

Products

Bar none, Amziol products are the absolute best you can buy! For everything you own, farm, lawn and garden , cars, trucks

Best oil ever

Just turned 120,000 miles and the engine is very quiet and runs like new.

Sig-series 5w20

Excellent engine protection with the long term performance provided by Amsoil. Consistently better mileage than any other lubrication product. Would recommend to anyone wanting the absolute best in engine protection and lubrication.

Only oil I'll ever use

Use this in my 2011 Camry with 250k miles since new changing it every 25k miles

396K km and running well

My go to oil for 05 and 10 Impala. Used Amsoil since buying the cars with approx 60,000 km on each. 40,000 km oil changes within 12 months with a filter change at around the 20K km mark. I had 345K on the 10 Impala when the transmission gave out - motor was strong. The 05 is still running well with over 395K kms. Has to have something to do with good quality oil.

Best!

I only use Amsoil. Wouldn't waste my time, money or vehicles on anything else.

Best Protection

I have used this for a few years now and has provided the best protection out of all the oils out there for me.

satisfied user

My '14 Outback V6 requires 5W-30 I have used Amsoil every 5,000 mile or 6 months to meet warranty requirements since my first oil change at 1,000 miles in 2014. At 50,000 miles the V6 still hums like a sewing machine

Well satisfied with a good product

When I purchased my 2014 Tundra, I asked the dealership service writer I have known for 25 years for a recommendation regarding motor oil. He suggested Amsoil. I have been using Amsoil in my Tundra since October '13; I also use Amsoil in my Highlander, my wife's Camry, my Honda lawn mower, and in my John Deere Diesel garden tractor. So far, everything still runs like new.

Great oil

I run Amsoil in my truck and snowmobile.

This oil brings out the power

My car runs way better and bring out lots of power

Awesome Oil

Signature Series oil is unbelievable. I have had multiple vehicles with two hundred to three hundred twenty-five thousand miles on them and Amsoil keep clean like new. I also have 22 and 38 year old tractors that use no oil.

All good

Never in doubt...

I would be this product again

Hands down the best oil I've ever used in all my trucks and suvs
I saw improvements in fuel mileage
Lower rpm at idle
Cooler temperatures
I will never use anything else but Amsoil

Best oil ever

My bmw 328 run super great ... incredible in cold temperature....thanks

I would buy Amsoil time after time because I want the best!

I only want the premium best for my new Camaro SS-That is Amsoil!

This is the only product I run in my cars.

I use Amsoil Signature Series in all of my cars, from my truck, daily drivers and four various Porsche models. Nothing better and I will never switch!

Good stuff

It's expensive but for protection it's worth it. It seems to be the best wear protection of any oils I've tried in my various vehicles

Oil

Use it in all my cars, only oil that my cars don't drink like water.

Worth the high cost

I have a 2016 Camaro ss that started to burn a little oil with the valvoline full synthetic I was using. I started using Amsoil and two oil changes later the car hasn't burned a drop of oil and the oil seems to hold up a lot better. I will only be using Amsoil in my cars from now on.

Motor Oil - Diesel

Been using this oil for years.

A must have oil for the cold region.

Switched over to Amsoil in my F-150 with the 5.4L Triton. Switch over with just over 100k on the truck. I did use the engine flush per recommendation. I did notice that it is quieter on start up at sub-zero(-20f) temperatures. I have oil pressure at turn key! A must have in the Northern area.

I will buy and use this product again

I use this 5w30 in a 2006 explorer with over 200,000 miles and have no issues.

Love it

Best oil in the market use it on all our cars!

Great Product

Best oil on the market. Buying anything else is foolinness.

Fluids

The type of oils and fluids that go into my vehicles etc hands own #1 in the business you want the best from your vehicle then you have to use the best.

Excellent Oil

Excellent oil, I use Amsoil in all my mechanical equipment and they last a long time!

I Will continue to buy again and again!

I use Amsoil in my pick up, I like the piece of mind of knowing I have the best possible protection for my engine.

I continue to use this product

I am a relatively new user, but the research I have done has all been positive and enthusiastic, both from friends and online.

Great Oil

Decided to switch from Mobil1 to Amsoil for my Toyota cars. Went with the 25,000 mile oil so I don't have to change oil so often. Once a year oil change is perfect for me. Very pleased and it's such a better oil.

Confident User

Used and followed Amsoil for most of the last 45 years. It's always got the job done and the 5W-30 has worked great whether it's winter or summer. Change it once a year and forget about it. Even in my older high mileage cars, they make it from oil change to oil change without having to add. I love it. Can't understand why anyone would use anything else.

I definitely would buy Amsoil 5w 30 again

I use the Amsoil 5w 30 and the Ea Amsoil Oil Filters in both my 2018 Chevrolet Silverado and Tahoe. The quality and durability of the Amsoil is second to none.

like this oil

noticed when i put it in the engine ran quieter

Great product

Great product. I drive 120 miles a day to go to work. I increased my gas mileage and can tell the difference in the engine in how quite it runs.

buy this oil for all my vehicles

I use Amsoil for all my vehicles, have done so for over 15 years, won't trust their protection to any other oil.

Signature oils

Great products keeps engines clean and lubricated

Only oil for me

I will only use amsoil products in my vehicles and for the price u can't beat it

Best oil in the USA

I use this oil in my ZL1 Camaro and it makes the car run cooler and the means that less friction, i have no dislikes

Nothing better

Nothing better out there for my 6.4 hemi.
And my sxs vehicle's

Great Oil

I use this on my 2008 Volvo C30R with 166000 miles. Engine runs smoothly with amsoil.

Great

Oil is the best

Only the best for my Hellcat!

Have used Amsoil on my 2018 WB Hellcat since 1st. oil change with Extremely satisfying results. So happy use it in my Jeep Wrangler as well. Nothing but the best for my vehicles.

Good product

This was recommended for my vehicle and I have used other amsoil products in other vehicles and have blessed using it. Tks

Awesome stuff

I have been running an amsoil product in my 08 Toyota Tundra since new. When i say new i mean when the engine had enough km's that it was past the break in point I switched. I ran Amsoil XL for several years at the recommendation of the place i get my oil changes at. Changed it out every 6 months. I am pretty sure Signature Series was never recommend as they would only get my business once per year. Not knowing exactly what Amsoil had to offer I did some further research and discovered this Signature Series oil. I now change my own oil as I am able to order directly from Amsoil. I have been running Signature Series for about 5 yrs now with basically a once a yr oil change. I mainly drive secondary rds but come fall hunting seasons i am all over the backwoods. Here where i live it can get down to -30 at times during the winter. The flow rate is excellent in extreme cold as well as I always watch oil pressure gauge and no matter how cold it seems the needle always jumps up quickly on cold start up. My truck now has 271,000 KM's on it. Even with once a yr oil changes the oil doesn't look alot darker than it did when i changed it the previous year. Great product I can't imagine running a different oil in. I now have my son's truck running on Signature Series as well. I plan on putting 1 million Km's on my truck!

MPG

2017 Tacoma TRD Off Road struggles to get 18mpg. Used Signature Series Synthetic and now getting 20-21mpg.

Since I've discovered this product.

Discover Amsoil in 2012 & have slowly been converting all my vehicles to Amsoil. Even converting friend but they are harder to convince because most rent their cars & basically don't care if they last or not. Consumer society. That being said all my immediate family use Amsoil.

25+ years of use

Save time, money and engine wear. Have used Amsoil in all my vehicles and equipment for over 25 years and and have not experienced an engine failure.

Love the Extended Drain Interval

Been using Amsoil in my Dodge Dakota since I purchased it 13 years ago. Today it has 250,000 miles on it and still runs great.

Only the best oil for my Jeep

I have done only a couple of oil changes on my low mileage Jeep but I wanted the best oil and have no regrets with buying AmsOil signature series oil.

It's amsoil

I'm not sure how you review oil.
When I opened container, the oil, was oily. So I put it in my engine.

My engine has not blown up, so I assume it's the right oil.

I'll keep buying their oil, until it no longer feels oily to the touch straight out of the bottle.

I use this product all of the time

I have a 96 Chev C-1500 with over 360k that has had AMSOIL in it for over 350k without any failures. It runs good and sounds like it has a new engine in it, but its the original without any major work on it. I also use AMSOIL in the transmission and the rear gears. I have had a valve cover off and you wouldn't believe how clean it was on the inside, no sludge.

A well oiled machine

Feels and runs smoothly !

I would recommend to everyone

Excellent protection

I will use this only

I highly recommend this product. I only use amsoil products in everything from my compressor to my vehicles. They have done there homework to produce great products.

Good quality

AMSOULS NEED RETAIL OUTLETS
TO ADVERTISING.

Best on the Market, Hands Down

I use Amsoil in everything from my truck to my motorcycle, lawn mowers, generators and anything that takes oil. I also use the oil filters, gear oil, and everything that Amsoil makes.

I love it

Oil pressure is improved with this product

Only the best

While I can't say the car runs better with this vs another top synthetic, I have hundreds of thousands of miles on my vehicles with this oil only changing once a year. Great stuff!

Recommended for Boss 302

Trusted product! This particular oil was made for my engine what can you ask more? They took the time and knowledge to make the oil possible for my car... its really a no brainer! Nice to have a compagnie that's back you up!

Best oil and filters on the market in my opinion

I have been using AMS Oil for 18 years and wouldn't use anything else. It is by far the best and all of my vehicles with several hundred thousand miles on them combined is the proof.

Retired Truck Owner/Operator

I doubled my miles between oil changes which saved me money, I use it in my small truck also.

Test Results Fantastic

So I run Amsoil signature series in all my vehicles. I run 5w-20 in the 2015 Jeep Rubicon Hard Rock and when I changed the oil at 7000 miles of use the oil lab came back and said to change at 9000 next time and see how it's doing. The wife's 2011 Subaru Impresa 5w-30 oil was changed at around 7000 miles as well and the results were the same! I think once the oil is tested at 9000 they will most likely advise I go even longer. They measured for contaminants as well as assessing the TBN which both came back outstanding, and both engines have zero issues. Black Labs is where I send my oil. The higher price for Amsoil is worth it in my opinion especially when I can go so long in between changes. It pays for itself.

I have used Amsoil in most of my vehicles for many years.

I have numerous vehicles with 60-400,000 miles on them that have been running Amsoil most of their lives. All still have original engines. What more can I say?

Definitely would buy it again

So far so good. Only have 26k on the car so far.

Best Price

The best price and solid transactions

I use Signature 5W-30 in my daily driver

Used to go to quick non-synthetic oil change place until they stripped my oil pan threads. Decided to change my own and use Amsoil. Was changing every 5000 miles before now going 10,000 miles. Materials cost is more, about what materials and labor was before but I'm going twice as far.

Great Oil

Have been using this oil since around 2006. My 2006 Ford E350 work van has145,000 at 15,000 mile change intervals before I sold it . My 2006 E350 15 passenger van currently has 185,000 at 20,000 mile change intervals. Great oil have had no issues with it.

I would buy this engine oils again

Engine has been running smoothly after changing into this signature oils.

Been using it for years

Best you can buy for your vehicle.

The oil I've been looking for

I was nervous switching from high mileage to a full synthetic, but 84 Chevy pickup now runs better than ever and actually has less leaks now. I also run this same oil in my 84 Honda Nighthawk motorcycle.

If you want the best oil this is the one.

All I use in my vehicle's is Amsoil ...I wanted to put good oil in my vehicle's so tryed Amsoil and been using it for 20 years now. It's the best hands down period...

Highly recommend.

I have used this product for years, I wouldn't trust any other product in my vechicles.

Using this oil from here on out

Solid oil that's maintained it color and viscosity for 3k+ miles of spirited day to day driving

Simply the best engine oil for GDI engine

This oil controls carbon buildup on the intake valves of gas direct injection engine. lowest evaporation rate.

Amsoil Signature Series

I have been using this product on my 2010 Mazda 3GT since new. I am nearing 186,000 miles on the car and have the oil checked at every change. The analyzers are always telling me the oil has more life left and everything looks great. I will be using this product in every vehicle I own and recommend it to everyone who asks. A first rate product!

Highly recommend this product

As a mobile sharpener, I put a lot of miles on my vehicle. By using AMSOIL, I have peace of mind that my van will run smoothly for a very long time. I highly recommend this product!

Yes

I use product in my 2016 2.4 litre canyon . It's a great product but my engines seems consume some of it . A litre on 5000 km disappears through exhaust .

Will continue to use this product

Long lasting great protection

Simply the Best

Going on 7k mile oil change...oil still looks new... Car performing well. Amsoil is the best of the best.. you get what you pay for...no more mobile one or Royal purple for me ..never again.

I WILL BE BUYING MORE!!!!

I wouldn't use ANYTHING ELSE!!!!!

The best motor oil and product !

I be using amsolil in all my car back front the 1990 I never have any engine problem. All my cars run good and I put a lot of miles and the engine always run good ! I have 2014 Acura MDX I be using amsoil when the car make 7,500 and the car still running like new !

I start using Amsoil in the 1990

I be using amsolil in all my car back front the 1990 I never have any engine problem. All my cars run good and I put a lot of miles and the engine always run good ! I have now a 2018 Accord that only have 9 months and have already 31,000k and I be using amsoil when the car make 7,500 and the car still running like new !

Sense 1982

This is hands down the very best oil you can buy. Been a faithful Amsoil user sense 1982. The very best protection there is

I only use this product for my cars

When servicing my vehicles with Amsoil Sinature series oil, the dealer always comments on how there are no leaks. It also increases my trade in value when I upgrade. Never a complaint.

Great product

Using this Motor Oil puts me at ease and you can depend on it to so it's job. I have used Ams Oil for years now and it keeps your engine running as quiet with nearly 200,000 miles on it as the 1st day you got your car. It definitly keeps your internals sludge free. This I have experienced first hand. Oil pan and valve cover removal.

This high quality product is the best!

I use Amsoil products for all of my lubricants in all my vehicles and equipment since 2015. I am very pleased with the performance and protection and am convinced these products are second to none. I bought an F-150 in 2015 that sounded like the transmission was ruined, put in an other brand of transmission fluid and nothing changed. I then put in Amsoil transmission fluid and it immediately fixed the problem. I haven't looked back since. I know the products might be a little more expensive then some, but they are the best. Thank-you for putting out a great product that is a valuable investment for hard-earned money!

Awesome product. Will be my only oil from now on.

Great Product, run the small engine oil in my Kohler whole house Generator.. runs cooler , quieter and I know I'm using the best oil between change intervals... also I have a 2005 F150 with the 5.4 Triton Engine.. everyone knows about the problems with these motors.. switched over to Signiture 5w-30 a couple years ago.. runs a lot quieter , cooler and just seems to purr .. yes I know the motor specs 5w-20 but it does honestly run better and have had 0 issues with the motor.. ... Bought truck new in 2005..

Great products

Use it in everthing

Quality

I use Amsoil because it is the best oil. I recommend it to all my friends.

Best protection for your engine - period!

I will only use Amsoil lubricants in my vehicles and power equipment. Amsoil products are the best protection I can get and give my investments.

Best oil I've tried

Had royal purple in my wife's Dodge Durango 5.7 V8. If it sat for a few days and I started it I could hear a valve knock that lasted a few seconds and sounded bad. I've had this amsoil in with amsoil oil filter and I can leave it sitting for a week and start up sounds completely normal. I can tell I'm getting proper lubrication and I trust amsoil because of it. Also put it in my Cummins diesel and it's smooth as glass as well. I think I'm amsoil for life.

Best oil on the market

I have been using Amsoil oil and filters for about 20 years and in my opinion they are the best on the market. I ran a 2001 Chevy Blazer 25K miles between changes with absolutely no problems and it was still running perfectly with 109K miles on it when I sold it.

Great product

I use this oil in my 98 wrangler works great

180k strong

She still beats a GT Mustang after 14 years, running Amsoil since the start

Best Ever!

I run this in all of my vehicles. It is worth every penny for sure! You won't regret buying this.

The only oil I will use

Phenomenal product that is worth the price. Yes it is expensive initially, but it has stood up to some hard usage with issues. 20K oil? Bet on it!

Awesome Product

This is the best oil I have ever used

A product I trust and use!

Using Amsoil products for over 20 years and nothing else...

Amsoil is great

I use Amsoil, dual bypass oil filtration, and test lab analysis to support extended oil changes. Lab analysis has shown me I can run almost 40K miles without changing oil. I sometimes drive 1000 miles a week or more for my job; and monthly oil changes simply don't cut it. Amsoil does. I spare not the miles and trust Amsoil to go the distance; I have independent lab analysis to demonstrate it.

Best Oil Around!

It's the ONLY oil I will allow to be used for my Shelby GT 500! Provides the greatest protection for the high performance engine!

Only oil/filter i will ever buy

I use this oil in my 2013 F150 with the eco-boost 3.5L engine. Truck burns or uses zero oil between oil changes(once a year). I only drive about 7,000 miles a year. I use Amsoil because I know Amsoil makes the best products available.

Long time user

Been using AMSOIL since the 70's in many cars and trucks. Sold one truck to a mechanic after 204K miles. He said it was the cleanest engine he' ever seen.

If your not an Amsoil guy, your doing it wrong

Customer for 7 months. I can't say anything someone else hasn't said already. This was for my Dad's girlfriend car. We have my truck, his truck, her SUV, my mower all on amsoil. My truck is all done. Engine, tranny, rear end, transfer case. Waiting to put in coolant. It sells itself. They say everything drives.i use signature series and will never use anything else in any motor I ever own.dealerahips can say whatever they want, just stinks you have to change within a certain mileage to keep warranty cause this oil goes forever compared to rest. Use it and see!!!!

Good oil, keeping the motor clean

I chose to go 0-40 for both cold flow and film strength at the running temps. Motor is getting cleaner every oil change and is running great. I tow with confidence and will continue to run the first in synthetics

Best oil you can get!

After switching over to AMSOIL Signiture Series 5W30 in my '07 Prius, I couldn't be happier. The gas motor is running very smoothly and more efficiently since I have owned it! Not too shabby considering it has 124K+ miles on it! This oil is the real deal. If you are serious about keeping your car in the best condition for as long as possible, there isn't a better oil out there that can deliver on that than AMSOIL.

Best oil I have found yet

Back in 2006 I have swivhed from other brands to Amsoil. Based on some independent test results, and most importantly a friend. Who have tested his 12000 mile oil being Amsoil, on 45000 mile vehicle, that used amsoil since new. Test results sugested fillowing: 1) oil is 6000-7000 mile old 2) engine is 15000-25000 miles old 3) if lubrication continues as before, engine should ladt over 300000 miles.
That was enough info for me to switch, also Mobil 1 that I was using at the time, came with less promising test results.
Since the switch I have been using Amsoil in every car, and truck I owned. Never had a failure due to lubrication. And most importantly have saved a bunch of money, on changing oil once per year. Signature series, along with EA filter can last up to 25000 miles. I would never go past 15000 miles.

Best stuff

I have a 05 ram 2500 HD 250000 miles on it still runs like a dream

In year's past ....

I used this blend for years until I changed to the European blend and it worked very well ....

Yes

Good

Best oil you can buy

The highest quality oil for everything with and engine, hands down.

Great stuff

I've used Amsoil over the last 30 plus years and never had a problem with any of the product. I use it in offroad vehicles, 4x4 Jeeps, turbo charged engines, NA engines and anything else that benefits from a high quality synthetic lubricant.

I have been using Amsoil products since 1984.

I have been using Amsoil 100% synthetic engine oils in all my cars, my wife cars since 1984.
At first it was 10w-40 AMO, then in 2002 I switched to 5w-30 ASL. I refuse to use the 5w-20 and 0w-20
oil, I feel my engine is better protected with the 5w-30. I also use the oil filters, the grease.
They are simply high quality, great products and the service is great. I order online via the Amsoil website since 2001. I get my order within a couple of days, and there is never any mistakes.

Top quality oil

I have used Amsoil signature oil for over a 100,000 miles in my vehicle. I tried other oils but they did not last or perform up to my standards.

This is my go to for my truck

I can go a long time between oil changes with the signature series 5W 20 oil, it is amazing how much better my truck has been running since I have been using it. I haven't found a con with it yet, just all pros!

GREAT STUFF

I have used Amsoil for many years, I use it in all my vehicles everything from my daily driver to my classic and antique cars, I even order it for my friends and family who all love how it works and the convenience of use ie. Once a year oil change.

I would buy this oil again

.............. .............

Good Product

AMSOIL Signature Series 5W-30 Motor Oil
keeps my car running smoothly.

Great product

This product has Pierier antiwear property is

I always use Amsoil

I've been using Amsoil oil for more than 20 years so when I bought a used 2011 Toyota Highlander that requires 0W20 oil I chose Amsoil Signature. I noticed that the my SUV used less oil with Amsoil compared to whatever the dealership put in it. I've had several vehicles that even after 10,000 miles used virtually no oil when using Amsoil.

I love the oil, all of it.

I have been using Amsoil for years. Commutes for me is 40 to 50 kms oneway and I can run Amsoil and never have to add oil. Had an old car overheat in Calgary one summer due to traffic on the deerfoot trail and there was no problem afterwards with the car or the oil.

I have bought this for years!

I have used this product for years, it gives my vehicles top notch protection!

Beats sliced bread and bottled beer

I have used Amsoil products since 2003. Never a problem. I have recommended it to friends without any qualms.

Best product ever, life time customer

Ever since discovering this oil in 2005 I've never used anything else, and it's never let me down. 15k miles between oil changes and it's still gold in color not black like others.

Love this product

I use the product in my 2013 Dodge Ram 5.7L.
I believe I have increased fuel mileage and the truck runs great!

I will never buy another oil again

I have used amsoil in my motorcycle and personal vehicles for years. All of them perform perfectly.

I would buy this product again and again

Product works amazing! No issues

I will buy all amsoil products especially oil an power foam

Love the oil never had issues power foam is the best out there if ya know how to use it correctly.. very happy with the results and products..

I will use this for as long as I live

Amsoil is de bessss!

Never lets you down Never fails. Actually works as advertize

Smilinjack has been using AMSOIL 1030,1040 2Cycle oil, Power Foam, oil and air filters and Performance Improver continually since 1979. Once we tried it, have never ever needed or used anything else. Automotive use, lawnmower, lawn tractor, boat motors and my portable generator all perform well with AmsOil in the crankcase. Excellent products. Knew a good thing when we first found it and will never go to anything else. EOM

I use nothing but Amsoil for the last 8 years.

Great product, love the extended drain capability.

Amsoil Signature Oil

I have been using Amsoil in every vehicle I have owned for the past 15 years. I like the extra protection and only changing oil once a year.

yes

your car runs great

I keep this stuff in my shop by the case.

I just had a 600 horse 460 Ford built and put in my truck and this oil is the best insurance for a hydraulic roller cam motor in my honest opinion..

Great product at any price

This product goes in all my vehicles!

Will buy again

Used it in my 2015 Ford Fiesta rally car. Seems to be working.
will buy again in couple months when time comes to change oil and filter!

ONLY THE BEST WILL DO!!

Well, I am not the guy who owns a mega-truck or 5 SUV's. I have the "love of my life" who's stuck with me for 38 years and a major cardiac failure. My goal is to make sure that this investment of my life sticks around for awhile. Everyday she gets in her 2013 Honda CR-V and takes to the roads. Her rig WILL have the BEST I can afford protecting her. This is why when it comes to the products you make, they will be used. When the BEST is used there is no need for excuses!

Don't know where to start when talking about GREAT PRODUCTS!

I have been around cars and trucks since I was 11 years old...rebuilding, normal maintenance, restoring, and mechanical. At almost 70 I can tell you that my pride and joy is a 1998 Chrysler Town & Country LXI mini van. I proudly have 385K Amsoil miles and it still runs like new. I get exceptional mileage, no smoke from exhaust, no rough idling, no engine noise (that most older motors get), and can say after sitting in the drivers seat all those miles...I still love to drive it and see what new gets better! I am constantly surprised at how smooth a quiet the motor runs. When I take it get my tires rotated they always comment on how well it runs...here is the irony. When trying to explain about additives there is a blank look as people just don't understand that synthetic oil is engineered not manufactured. A lot of time, research dollars, and effort has gone into the making of each product. I will always explain the benefits of Amsoil when asked...just get tired of people that are ignorant to the science and technology that has made this product what it is. I have been a 20+ year user and will always continue! Thanks Amsoil for sticking to your desire to be the best!

I will buy this product again

I use this in all my car's and trucks

I wont buy anything else!!

Best oil on the market!

I like Amsoil

I've been using Amsoil products for many years. I don't have to worry if I've gone over the 5,000 mile interval, because I know Amsoil will protect my engines. The oil filters are top grade, and great to use with Amsoil. I also use many other AMSOIL products. The gun cleaner and gun oil is excellent for my police service revolver and I use it faithfully, knowing it will protect my pistol, shotgun and assault weapon. The cost may be slightly higher, but the protection is excellent and guaranteed to perform.

Best oil on the market

It's simply great oil made for great engines.
If you have a boosted engine stick with the best, you won't regret it.

So not want to useat any other oil

Have used for years on my 2000 Chevy Impala, 1995 Toyota corolla, 2010 and 20 12 Toyota Prius, and will be on my 20 17 Rav4 b

Ow20

Oil exceed all expectations.

Love this product

In my truck

Great product

I use it in my 2014 Chevy Silverado

Only product I use

Since day 1 of the first oil change, and several others, 45K miles later it's still running like a champ. I've been using Amsoil for years. Nothing will change my mind.

Great all season protection, IMO

Been using this in my DD/cars for the past 10+ years and never any oil issues.
Good stuff.

11 years of the best!

I converted my car to Amsoil 11 years ago when I first bought her. She was 4 years old and had 78k miles. Once I changed her to Amsoil, she instantly ran better. Now at 176k miles, she has the cleanest valves any mechanic has seen! I'm proud to be raised on Amsoil

The Best

I use Amsoil Signature Series 5W-30 sinthetic oil in my 2006 Solstice and my 2013 F-150. Amsoil is the Best and wouldn't use anything else.

I have bought, will continue to buy

This is a great product and I use it in all of my vehicles. The biggest difference is that all my motors run quieter than any other product I have tried including royal purper. Could not be happier.

Amsoil is the only fluids I use, period!

I have 0 complaints about any product that I've used yet. My 06 Silverado and 07 Trailblazer both get Amsoil. 15k Mike changes with 0 issue

1ST TIME BUYER

I HAVE A BRAND NEW 383 STROKER ENGINE IN MY 2004 SILVERADO. IT WAS RECOMMENDED TO PUT A GOOD OIL IN MY ENGINE AFTER THE BREAK IN OIL WAS CHANGED.READ REVIEWS ON SEVERAL DIFFERENT OILS AND REALLY LIKED WHAT I READ ABOUT AMSOIL. WHEN I FIRST GOT MY ORDER IN THE FIRST THING I NOTICED WAS THE BOTTLES WERE MADE DIFFERENT THEN ANYTHING ELSE I EVER USED. THEY WERE THICKER PLASTIC AND ARE POUR FREINDLY. DIDNT NOT HAVE TO WORRY ABOUT SPILLING OIL ON MY NEW ENGINE.

Best there is

Best you can buy.

My go to oil

Great product

I WILL buy this product again.

AMSOIL is THE ONLY oil and lubrication product I use in everything I own. I would put this up against any other synthetic lubricant any day.

I Would definitely buy this product again.

I have been using this oil in my06 Dodge Ram for years. Makes better oil pressure than other brands.

Great oil

Run, it in all three vehicles that call for 5 w 20wt.

Quality product

I have used Amsiol products in all my vehicles for several years with good results.

Titan Loves It

Switched to amsoil and my engine is quieter, and runs better. I tow a lot with my truck and know with amsoil that the oil is breaking down under heavy load.

Few choices

Not many choices for 5w-50. This is the only real quality option. Thanks for making the wt.

There is no other oil like AMSOIL

I own a pickup and two autos, two utility tractors, four chain saws, three weed eaters and eight small engine machines. I have AMSOIL in each and every one. My Pickup is used to pull a large trailer and for snow plowing for several customers. I also use fuel cleaners, fuel preserve products, oil mix and grease gun tubes. I have experienced oil leaking and oil burning motors stop doing both and a one pull start on the small motors.There is no other oil and other products that compare to AMSOIL.

Long time uses

Been using Amsoil 20 years and have had no problems. Put oil in my Durmax and put the big filter on and did need to change oil only once.
Amsoil has been making oil for years, now everyone is trying too.

I will buy this again.

I use 0-20 Amsoil in my Family crossover. I run it 15,000 mile between changes and the oil still looks clean when I drain it.

I will only buy this product from now on

The Signature Series oil is the best and most money-worth-it oil that's available from Amsoil...period!

Keeps my cars running long and strong

Minimizes actual engine wear while managing fuel economy. Yearly oil changes is great.

I will buy this product again.

I put Amsoil 5w - 50 I'm my 2012 Boss 302. Product works great for regular driving or hittting the track.

Have used this product for over 25 years

I used this product in my SUV, runs smooth get better mileage and start very well in extremely cold weather. I used their product in all my vehicles and small engines.

Incredible Stuff

Amsoil makes a huge difference in the performance and longevity of your vehicle. Nothing else goes into my cars, trucks, lawn mowers, chainsaws, etc.

I will buy this product many, many more times...great stuff!

I've been using AMSOIL motor oil for just over 5 years now and been very satisfied, no complaints...ever!

Great product

I use it in all the engines in my house. My cars, lawn mower, pressure washer and generator. I feel my equipment runs better and more efficient.

Use it in track car and without any problems

I use this oil in my track car. I have a magnetic plug and nothing has shown up there. The filter is also clean after each use (I check it). Oil pressures are good on track. I plan to use this oil well into the future.

I would definitely buy this!

I run this oil in my 2003 Honda S2000 and I love it. Had my head rebuilt and checked the cylinder walls, cams, etc. with 111k miles on the engine with force induction. There were barely any wear at all! I will always run Amsoil.

This is the only oil I will use is my Chevy Blazer

I use the 5W30 along with the Amsoil oil filter and I run it 15,000 miles before I change the oil. I also use the Amsoil AFT which can keep the transmission temperature up to 60 degrees cooler. Reduce friction and save your equipment

Been using for years

I use only Amsoil in all my vehicles--engine, trans, and differential. Best products on the market.

Will buy again

Lasts well. Color is still clean after 5k. Gas milage is slightly higher. No oil leaks in a Ford Taurus with 200k.

Great product

Great oil for direct injection engines

Been using this for 15 years

I've been using this since 2003 in my Toyota Solara that has the V6 which is prone to sludge. I now have 470,000 miles on it and still running strong and does not smoke. I change it and the filter about every 10 to 15 thousand miles, sometime longer.

Great Product

In work&personal vehicle.Work car approaching 300,000 miles-Starts easy in old weather-improves gas mileage-don't have to change every 3000 miles as you have to with conventional oil-can't think of anything negative

High Heat Low Friction

I use this oil in a variety of cars and trucks i service. Some of these cars are turbos and some are natural aspiration. No matter the heat load in any of these cars or trucks they seem to have extremely low friction when i inspected during engine rebuilds.

The Best Oil Ever Made

I buy this oil about once a year for a friends 2004 Lincoln Town Car. He only drives around the city and occasionally to Richmond Virginia. He always gets a 19~20 mpg in the slow city with the ac blasting and on the highway 25~27 mpg. That is a 280 hp 4.6 liter v-8. The engine runs so smooth now its a huge difference from before the use of amsoil.

Yes

In my motocycle

Simply the best

The to go motor oil for all 0W-20, 0W-30, 5W-20, 5W-30, 10W-30 applications except europeans.

My engine is super quiet now

My engine is really quiet now. That tells me that Amsoil is lubricating the engine in a way that the other oils can't. I changed all the fluids on my 2017 Chevrolet 2500 HD 4x4. Fuel mileage is up and vehicle noise ( engine, transmission, transfer case and differentials ) is down. it truly makes a difference.
I've also switched to Amsoil in wife's 2017 Ford Explorer, my son's 2015 Ram 1500 and my 2015 Tahoe Q7i SF boat.

Love this stuff

I use Amsoil products in my truck and my wife car. I started using Amsoil products in my race car many years ago and had such good luck with them I have been using them in anything I own with a gasoline engine. My truck has over 200,000 miles on it and it runs like new. We use my wife's car for road trips and I always ride with confidence in Amsoil products. I would definitely recommend Amsoil to family and friends..

oil

great stuff

I have been buying this product again and again

I have been using this product (5w-30 signature series) for sixteen years. A little better gas mileage and I feel the auto is better protected in our high heat that we get during the summers here.

Very good product and very reasonably priced

We Transport trailers with our pickup and run only Amsoil in it. Love the extended oil changes, especially since we run so many miles. Because of the ability to run more miles on it, it actually is cheaper to run Amsoil. Wouldn't run anything else!

Best Product on the Market

By far the best motor oil I've used!

Buy nothing but smsoil.

Use it in honda crv.Great oil. Long life.

Engine Oil

I only trust Amsoil in all of my vehicles.

Mechanics Amazed at inside of engine during gasket repair

A couple of years ago I had my 1998 Chevrolet Silverado in the shop for an intake gasket repair. About mid-day I received a call from the repair shop asking me what kind of oil I ran in the engine. They were amazed as they told me they had never seen an engine so clean inside. I told them I had been running Amsoil in the engine for the past 1.5 years. I had heard of Amsoil for years and talked to a diesel mechanic a few years before and he ran Amsoil in everything he had. I figured if a diesel mechanic ran it in his vehicles, motorcycles, and lawn equipment it was good stuff. I have not been disappointed, I immediately noticed easier cold starts and better gas mileage in my vehicles. With the miles my familiy's vehicles travel, a once a year oil change with the extended life best synthetic oil on the market is a convenient and cost effective solution for ensuring my vehicles engines are protected with great lubrication. And the added bonus of creating less waste for our environment is big for me as well. Convenient online shopping and dependable delivery put my vehicle's lifeblood in my hands within days of ordering it. Love the product and will be using it for years to come.
Dale

i would buy more

very good

yes i would buy it again

its a great oil I have every use in my cars!

Nothing but the best

I use Amsoil oil for everything I own car pick up motorcycle lawn mowers weed eaters I wouldn't use anything less
The best is Amsoil oil.

The Best

I have tried every synthetic oil over the years.Then I tried Amsoil signature series 5w-20 in my 2017 dodge Ram with the 5.7 hemi.Notice a big difference in smoothness and performance,like pouring a few energy drinks in the engine!!! I change my oil every six months, I wont be close to 25,000 miles but if I go over six months I know the engine will be okay. I have changed my oil with other synthetics that claim they can go 15,000 or one year, I changed mine at 6,500 and it was black and smelled burnt and was already starting to sludge.You won't get that with Amsoil. It cost a little more but it's well worth it !!! If your going to keep your truck or car for a long time Amsoil is the way to go,If you lease every two years don't bother.Give it a try it's THE BEST!!!

Only oil I use

The day I bought my 2005 F250 4x4 I brought it home and drained the stock oil and refilled with 0W20 amsoil and amsoil oil filter. Since that day my truck has never seen any other oil or filter. My truck is now 13 years old and it runs like the day I bought it. I change my oil once a year no more no less ! ! !

Signature series 5W-30 motor oil

I have used the Signature series oil for years. I like having the protective properties of the oil with extended change intervals. I have one vehicle with over 225,000 miles runs great and uses zero oil between changes.

A top oil

Use this in my Mustang GT....won't use anything else. Lots of debate as far as what's best but this is my favorite.

If there was a better lubricant anywhere, I would be use it.

I have been an AMSOIL user for many years, and as a mechanical engineer know the value
of proper lubrication. When you know a company is using the best additives, and the best base stocks for their oil, the choice of where to buy is easy.

In the final analysis, AMSOIL is a bargain compared to other brands.

Go with the best!

AMSOIL is in every engine I own!

Awesome

Simply the best oil to use. Thank you amsoil

High quality

Like all signature series it is the best oil I've used. Amsoil is one of the few oil manufacturers that shows testing results. They also sell testing kits. Their oil is top notch. Mobile 1 annual protection is basically a cheaper version of this. ( as it's not as good) if you want the best protection this is it. It also pays for itself as you can run it longer.

Too good to believe.

On January 20,18, I purchased a 2008 Dodge Durango w/ a 5.7, 4x4. It had 89,000 miles on it
The average mpg was 13.4. I was not impressed, and I don't drive like speed Racer. I do love the truck the power and the ride. I had used mobil one synthetic oil and filters with no change in mpg. So I decided to invest in Amsoil. I went with the recommend 5/20 signature series. I believe go big or go home. My mpg average moved up to 14.5 mpg. I also took a 4 hour each way road trip and got 19.9 mpg at 72 mph. I thought that was good for moving an 7000lb. all wheel drive vechical.
Any way I then decided to go all in changing front & rear diff and transfer case. I am now getting an avg mpg of 15.7. where I am now in Ohio it is hilly, so once I return to flat Fla I expect even more improvement. I am a clean oil fanatic, so I installed a oil bypass system. I have 2000 miles on the oil and it still looks like new. Yes bypass system and filters and oil cost a bit but the return on investment is after 25000, If you change your oil every 4-5000 Miles. The cost of Oil & filters saved, and engine wear reduction, pays for itself in no time. I keep my vechical s for a while. My suggestion is to change over to Amsoil signature series oil and 25000 mile filters. Oil is the cheapest thing you do for your vechical, do the best and I also suggest doing the bypass system. You save money in the long run while giving your vechical the best protection out there. I am Looking for a location that will use Amsoil to flush my transmission fluid. Even if I bring it in.
Hope you find this interesting and helpful.
Christian.

Good Oil

I run this oil in my 2011 Land Rover LR4 with a 5.0L that requires synthetic oil. I've had this oil tested at the manufacturer's recommended interval of 7500 miles and there was still some life left in it. The next time I went to 9000 miles and had it tested, this time the oil was no longer good, so I'll stick with Land Rover's recommendation. This is with Land Rover's canister oil filter. Amsoil doesn't make a long life filter for it.

Heck yes

Been using AMS in all my vehicles for 15 years . Have not had any engine oil related problems yet!

Over 200K and going strong.

I have a Toyota Corolla I bought new in 2007. It now has over 200K miles on the odometer. It has had only Amsoil and the only thing I have had to do is normal maintenance and it still gets over 30 mpg. Amsoil is the only oil I use in all my vehicles.

Best Oil on the planet

Had my oil changed at a dealership. They showed me some black sticky that came out of the oil pan. I called AMSOIL with my story and they had me send in a sample and some of the oil that drained. They did a thorough check and found that the oil had not failed in any way, some other contaminant apparently fell in while under warranty gasket replacement. Great company that stands behind their products!

Many miles!!

1993 Cadillac Sedan deVille. 4.9 liter aluminum block engine. 351,136 miles!! Enough said!

Use nothing but Amsoil in my vehicles.

Use at the recommended Amsoil oil change intervals. Never had any engine problems.

Tuffy

Just and great oil .

I would buy this product again

I run it and all my vehicles love it

I will be buying this product as long

2008 Lexus

AMSOIL beats everybody & More MPG

I am truly convinced that AMSOIL synthetic oil is the highest quality synthetic oil in the marketplace. I believe in my heart I get more MPG with this Signature Synthetic oil. I have been using it in all my hybrid cars for last decade or so. I love the quality, customer service and want to keep supporting this quality company. Keep up the good work AMSOIL.

I have switched to this exclusively

I saw a forum post with some oil test results. Amsoil was at the top of most of them. I switched to this in my 2002 Honda s2000. I'm 1 oil change in and my car hasn't blown up yet plus it burns less oil than with Mobile 1.

Best I've used.

Improves Gas Mileage.

Best oil for a hemi

I have a 2007 Dodge power wagon with the 5.7 hemi. I work this truck hard, and this is the only oil that cures the notorious hemi tick even with 130000 plus miles and oil changes every 15000 miles. Well worth it if you love your truck.

Love the products

A little pricey but peace of mind knowing that you have put the best you can buy into a truck that costs a bunch ! As crazy as I know this sounds I went from 13.1 mpg to 15 mpg only changed the oil . Is that even possible???

Awesome

I have nothing but good to write about this oil. I change my oil once a year, and change the oil filter twice a year, every 6 months, however. That's based on my driving and may not be on your driving habits. I would follow what Amsoil recommends when using their oil. Other than that my mechanic comments how great my car runs, because my last car I put on 250,000 miles without a major breakdown. I highly recommend Amsoil products.

Oil

Excellent product. Bike runs cooler and smoother

Needed the best protection

Just bought a 2018 Jeep Wrangler and wanted the best protection .... The same I had using Amsoil on my 1994 GMC 350k miles and 2003 GMC 230k..

Oil

I buy Amsoil because it has always worked for me. I have over 200K on my 97 Jeep, and the last 3 of my wife's vehicles went over 200K, one went to 286K before I traded it off.

smooth as silk

run it in my wife's CRV. I don't trust the Honda oils as they sludge out when converting to AMSOIL. Thankfully this is a new car, so I won't have this issue. A clean motor is a happy motor!

Overall happy

I am more than willing to pay a bit more than the rest to have significantly better oil protection. Read the independent reports, Amsoil is bar none the top dog.

Owner

I've retired 2 Ford E-350 vans, gasoline engines, both with 520,000 plus miles. I'm currently driving a third one, with 524,000.
I started using Amsoil, 100% synthetic, in each of these between 50,000/60,000 miles.
I also used the recommended Amsoil oil filter.
Changed oil every 18,000, and filter every 9,000.
Over the years and miles, I've saved myself a lot of time and money with Amsoil, over conventional oil and their oil change cycle, about 6 to 1.
Also saved a lot of money in vehicle replacement cost, because of each vehicle lasting about twice as long with Amsoil, over the normal.
Yes I'm a pleased customer!

Only oil I use

Change oil every 10,000 to 12,000 miles. I know it would go longer, but I know for sure my bike is ready for any demand I ask of it.

I would buy this product again, and I have.

I love this product. I have not had any issues with my vehicles since switching over.

My go to oil

Never lets me down and keeps my car running like a top. Black stone lab reports always come back good viscosity turns out little thin after 5500 miles.

AMSOIL products

My 1998 Chevy 4.3 truck has 350000km right from new I have used AMSOIL products bumper to bumper and never touched the motor or transmission. Even in cold weather at -25 Celsius not plug in it will start every time.I have been using AMSOIL products for 35 years and I am not about to stop.

I will definitely buy this product again!!

I use the 5w30 signature oil in my 2012 Chevy Sonic that I use for business. I use the car to deliver auto parts as an independent contractor. It presently has 339,000 miles on it and going strong!!

I would buy thia product again

It good oil and keep engine running for life

Great oil!

Amsoil makes one of the best if not THE best oil out there. You get great longevity out of their products, especially the signature series. I've been using that oil for a few years now and I noticed a slight increase in mileage and engine smoothness in my Accord. I just bought a new car and when the free oil changes(2 or 3) are up I'll be using Amsoil for sure.

Only oil I will buy

Amsoil is the schit hands down the best in synthetics

Amsoil synthetic

I have uses Amsoil for 8 years now. I go 20,000 between changes and 10,000 for a filter change in between. Never burn oil and I get constant steady power and great milage. Im convinced it the best oil on tge market...period!

Good stuff

I have been using Amsoil products for over 25 years, and now put it in my kids cars. Living in a place where dirt and heat are common place Amsoil has preformed above and beyond any other products I have ever used. With the cost of new vehicles I cannot think of a better product to extend the life of a vehicle. Goods stuff.

Only oil I can review at the time

Great oil, I normally use Mobil 1 and am trying Amsoil oils. I believe they are worth it. I still think they are expensive but they seem to last. No difference in performcance(like more MPGS) but I have noticed the signature series oil lasts more time without changing color like old/worn out oil.

Best performance oil on the market

Used in my SC, 2014 Ford Raptor. Longer oil change interval if required. Dependability during the most demanding conditions.

Great product love Amsoil products!!!

So far oil seems to be holding up well,never had any issues with Amsoil products.

I will alway use this and other Amsoil product.

Amsoil allows more time between oil changes with a filter replacement at 5000 miles.

I would buy this product again.

Switched to using Amsoil and noticed a difference immediately at how quiet the engine sounded. I also noticed a bump in fuel mileage.

I currently have a 2007 Mazda 3s with 115,000 miles on it and used Amsoil since it was new and it has never had any oil related problems or leaks.

Good product

Use this in 2 cars & 1 truck have over 105000 miles on Pt Cruiser, engine is quiet, & doesn't burn oil.

I highly recommend this product.

2006 Toyota Corolla. 250k miles with only 10 oil changes. The engine still going without any issues. Now I use it on my 07 Fj cruiser and my 15 Toyota Corolla.

Great results!

I have used Sig series 5W30 for the last 100000 miles on my 2003 Lexus es.Just had valve cover gaskets replaced.Tech said engine looked like new inside with valve covers removed..

I will buy this product again

My vehicle runs great

AMSOIL 0w20 and AMSOIL 5W20 synthetic motor oils.

I have been using AMSOIL Synthetic oils in my vehicles for over 10 years. Two Saturns (a 2000 SL2 & a 2002 SC2), Two Hyundai Elantras (2014 & 2017), and a GM Sonic (2015) . I have never had an oil related problem with any of the engines. There was significant affect on the LACK or wear on all of the engines I would recommend AMSOIL them to anyone who purchases a new car, or a used car with not many miles on it.

P.S. I have been buying NEW automobiles since 1970. I switched to AMSOIL synthetic motor oils in 2004, and have never used anything else in my automobiles (and my lawn mowers).

Have used Amsoil products for over 30 Years.

Used Amsoil OW-20 oil in the last two Hondas I've owned and currently in my 2017 Honda Civic turbo. Aside from the fact that Honda makes a very durable Vehicle the use of Amsoil OW-20 has without question lengthened the lifespan of my vehicles. I put close to 200,000 miles on the previous Honda's I owned and expect with normal maintenance to do the same or even better with my current Honda.

I have been using this product for many years

Wouldn't think about any other product for my 2007 Silverado that has 223,000 miles on it. I started using it back when i purchased my first new 2000 Silverado and have used it ever since.

No plans to change

I have been running Signature Series Synthetic Motor Oil in my 2010 FJ Cruiser (4.0 V-6) since it was new. The vehicle now has 146,000 miles on it. I drive 140 miles per day for work, towing a small boat for part of the commute. I consider the use of my vehicle pretty strenuous considering 1000 plus feet of elevation change, temps from 0 degrees to 105, all on horrible highways from the desert to the mountains, including a little off road crawling. I grew up around garages and race cars and do my own maintenance / oil changes and am always impressed with how good the oil looks when I drain it, even after max mileage intervals. I have had zero mechanical issues and get the same fuel mileage as when the truck was new. The one time I had a shop change my oil due to time constraints and other service, the mechanic commented the used oil looked and felt fantastic still, at 12,000 miles.
I use Amsoil products everywhere I can......tranny, differentials, transfer case. I'm sold on Signature Series Oil for all of my rigs, and sold on the people and service I get from Amsoil.

I would buy this again

Awesome oil. Makes my Cecile run smoother and quieter. I love Amsoil.

I WOULD DEFINETLY BY THIS PRODUCT AGAIN

In my 19 year old truck with 257000 miles, the performance improvement is noticeable.

Really wonderful oil

Started using the Signature Oils last year. I can tell the difference from regular synthetic oil. In the long run it's probably less expensive to use the Signature because of more then double the change interval.

Good stuff

You can't beat Amsoil, and at the price when you become a preferred member, the price is as good or better than most other oils.

One of the best I have ever used

Amsoil products are constantly the highest quality and the best protection for all my vehicles. It has revived and made my daily driver (over 20 year old vehicle) run like a top. It is the prefect addition to any vehicle that you want to get long use out of, and regardless of the environment have the best protection for your engine.

Started using it......will never stop!!! Whatever I drive!!!

Always heard about it in the past, but never tried it. Finally tried it and will always use it!!!

Best Oil

I've been using Amsoil in all my cars (6) for over 10 years. My 07 Honda Fit just turned 400k miles and is going strong, along with all my other cars running Amsoil. And I save money by only having to change the oil every 15k miles. Excellent product that actually saves me money in the long run.

Love this stuff!!!

I drive 150 miles daily and amsoil helps my engine run smooth and cool.. Even when I'm due to change it feels like oil not syrup... Great price for a great product.. would buy amsoil again and again.. Thanks amsoil

5/50 Signature OIl
