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

really like this oil

Use in my f-150 4x4

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

Have previously trid various oils in my 2012 Boss 302 & Amsoil 5/50 is been my choice since it came out .Great Stuff''''''

Signature 5-30 and 5-20 and 100:1 2 cycle oil

I installed 5-30 Sig in my Tahoe last May. Through this May I completed 10,000 miles including through a winter here in Northern Michigan. The shop I use was touting another oil and warned me that no oil could be used all winter in multiple cold or very cold start conditions and last through the whole winter. Well, I had the oil tested after a year and even in this harsh environment, the oil still had 3,000 to 5,000 miles of life left. Kudos to the product. Yes the Tahoe does use some oil--maybe 3 quarts total over that period, but it did amaze me that the oil held up and was still good after a year. Fuel economy on a road trip to Rochester, MN with a change of trans fluid to Amsoil synthetic showed an increase in mileage from about 19 to a solid 21-22 MPG. Fluids are the only change and this vehicle is otherwise a gas hog.

Use it believe in it

I have used this product for over 20 years. I have actually torn down an engine (oil pump shaft broke) that I used this oil in close to its whole life and the internals of the engine were remarkable. They showed very little wear and tear and none of the typical deposits you would see in an engine with 135,000 miles on. I know there is a lot of churn about who's best and so on but speaking for this oil it's worth every penny. Your buying peace of mind.

Yes

Good product

I will be buying this product again

I have recently changed to this after considerable research,

I am not going to stop using this product

Since I start using Amsoil signature zero 20 100% synthetic oil on my truck start ups Are much quicker and Engine runs more smoother and more power.My gas mileage has improved significantly

Great product

Start using AMS oil 10 years ago. After 250,000 miles car is still running great.

Reputation

Lots of confidence

I would buy this product again

This Product saves money. It gives you great protection for your engine over a longer period of time, so you do not have to change it as often.When used with the Amsoil Ea Oil filter, it does even a better job. So in the long run it is more economical to use.

Long intervals

As I have gotten older I like how I now only have to change the oil only once a year. I take care of 6 cars (mine and my kids) so this really helps me do other things besides changing oil.

I would buy this again

Long life offered

The only oil I use.

Been using Amsoil for years with awesome success. I always use their oil filters as well.

We are extremely happy with Amsoil

We love the oil , filters and grease. Currently we have just over 411,000 miles on our 2004 Honda Element. Thanks for providing such a high quality lubricant.

Excellent Product

I use this product in my vehicles that specify 0W-20. Since switching, the engines are much quieter and seem to run cooler.

Still going strong

I've been using Amsoil Signature Series in my 2010 Toyota truck exclusively. Eight years later and 200,000 km later it still runs like new. I wouldn't think of using anything else.

Cured Generator Oil Consumption

Great for my new air-cooled Generac 11kW automatic backup generator. It was consuming another well-known brand of synthetic 5w-30EP oil at an unacceptably excessive rate. After researching the various oil properties and what others with air-cooled generators down in hurricane country use, I decided to try Amsoil 5w-50. After switching my oil consumption completely stopped. I use it or Amsoil 0W-40 in all my small engines now.

I would buy this product again

Amazing product so good im happy i made the right Choice

I would buy this again

I started using this about a year ago and now have in my two motorcycles, my fiancés bike and a couple of friends.

I will purchase again

The Amsoil Products not only protect my vehichle to the highest standards,they save me time and money.

Great Product and Service

We have used Amsoil products in all of our vehicles for the past 8 years. The engine in our 2010 Equinox is still running strong with 155,000 Amsoil miles. We have used the Signature Series 5W-30 for the past 75 of so and even with the high mileage we lose almost no oil between changes. We do change at about 12K to 15K though due to the heat in the summers of central Virginia.

I would buy this over and over again.

I use this in all for vehicles I own for the last 20 years. My V10 Motor Home, my Hemi SUV, my V-6 convertible beach cruiser and my classic convertible street rod. Extremely versatile and has never let me down.

Top oil, over every other on the market.

I've been using amsoil 35 years, I believe it's what gave me 450000 miles on on a 77 Porsche. Today I used it in my 18 Kia soul turbo and 16 Kia turbo koup, read the specs it's the best oil for any application.

OIL

This is the only oil I use in all of my vehicles.

Amsoil is good stuff!

My engine has 245,000 miles on it, (second engine in the car) and I have used Amsoil for about 2 years. I recently had an oil analysis by Blackstone Labs, and they told me that the wear I had represented about 5,800 miles, but I had actually 22,600 miles on that oil change!! I could have run until 25,000 miles, so next time I will.

Only oil period.

Use this in my 2017 Kia 3.3 and like that I save money with my longer oil change interval.

My F150 and Highlander both run with Amsoil Signature

My vehicles never run better. I like the convenience of changing my oil once a year.

Best oil

I have been in the automotive industry for 45 years and have seen all kinds of oil and lubricants. Many claim amazing things. My personal experience with Amsoil has been long term. First my race bike. Nothing compared to the performance of Amsoil. Runs cooler, lasts longer, overall good results. My truck now has 343000 miles. Still does not use any oil. My Harley picked up 3 miles/gallon and runs cooler.

Gets the job done

Great product

Love Amsoil

Amsoil is the only well we use in our cars. Are even got my family and some of my friends to switch

Long time user

Great oil

Great Stuff. Highly Recommended. Awesome performance

Here in Edmonton, Alberta. We've got crazy And confusing weather. The cold gets up to -50 So this Oil does Absolutely great performance. You've gotta have this in coldest weather.

Will continue to be a customer

Just recently changed my C6 Corvette to Amsoil. Looking for cooler operating temps and the reduction of lifter noise on cold starts. Took a 200 mile trip ran about the same temps as my previous synthetic oil. Engine seems a little quieter with cold starts. The cruising season is just getting started her in Ohio. The true test will be when I track the car at some of our clubs autocross races and high speed events. Two other friends have witnessed improvements with this product and switched based on their recommendations. They both race frequently and push their Vettes to the limit without any issues.

delivery service

seems to be working good. I put a 100,000 miles a year on. does not keep engine as clean as redline. lots of varnish from amsoil at the 100,000 mile mark. redline at a 100,000 looks just like knew inside the engine.

Yes

I started using this oil many years ago. When first bought it I used your oil filter and oil I put in my Ford 150 pickup truck 2002. I left in my truck for 6 weeks and drained the OIl and put in new filter and oil this cleaned the inside of my motor now the oil stays very clean. I now have over 363,000 miles on my truck still running strong

again and again

Amsoil oil is amazing. You are the best.

Shmoov...

I use in a 1999 Acura CL/3.0 coupe...starteed @ 40,000, and have used for last 180,000...car has 220,000, and runs as shmooov as any vehicle out there....@ 185,000, I changed the transmission fluid, using AMSOIL transmission fluid...aGain.....shmoove shifting....Best product for any vehicle!

I have only ever used this in my truck.

Best synthetic on the market. It's the only thing I use in my truck.

Great oil as always.

As always, AMSOil didn't disappoint. Ordered this for my mom's 2016 Honda Accord.

It's amazing oil

Super impressed with all The Amsoil products. Extebdes oil change intervals makes it a no-brainer.
vehicle
Vehicle runs so much smoother, better gas mileage, it's a win-win

I would buy again

Use for my car

I run this oil in all engines I own..

I always say that if Amsoil don't know how to make Synthetic Oil NO ONE does..
Because they have been the first since 1972..

1999 z71 truck

300000 miles with once a year oil change. Amsol is the best

...

Great products

Very good product!

I use Amsoil in everything machine I own. That Amounts to one diesel pickup to three gas pic up and two mustangs one being a 2011 Shelby GT500

Best product ever for use in your car

Amsoil protect my crankshaft when my oil pump failed and I get better gas milage, epa rating for my car is 35 mpg and I repeatedly hit 40 mpg.

Good Stuff...period

2010 Toyota sequioa w/ 200k on the clock.
Doubled oil change interval to 10k, doesn't use a drop between changes. Frequently idle and tow in hot Mississippi weather. Noticeably quieter valve operation over other top shelf synthetics. I just did a 200k service and noticed there is zero sludge in the engine. It was as sparkly as a transmission.
I expect 300-400k out of this engine but it is a Toyota not a Ford!

Great Oil

The best oil I've ever used.! Hands down!

5w20 signature oil

2013 Kia Rio o my has a 3.5 qt capacity. Best oil I've seen for this scenario

Love Amsoil

Only Oil I will every use on my high performance cars

I would definitely buy again.

Used for engines and trans. I researched oil products IE: Royal Purple, Mobil 1, and Amsoil. Amsoil won.

Yes

On thanks

Subaru calls for this Wt oil

My new Outback calls for 0-20 oil. This is a difficult thing to believe in considering I am old sckool and would rather have a heavier oil in the motor.
So if I am going to put thin oil in this new car, then I want the best I can get.
I been using AmsOil products for a while now and have no complaints .

My new favorite oil!

My 302 race engine loves it! My old oil would barely last 1,500 miles but signature series is still golden after 5k! Thinging about swithing everything i have to it and see how a stock engine does up to 15,000!

The only oil I will use.

The best oil I have ever used and I tell everyone I know.

That's the one for my car

For the long mileage & city

This oil is some awesome stuff.

Unlike other oils I have tried in the past this stuff seems to work very well in my 5.3 liter vortex, she runs much quieter and cooler then before, I was a big a mobile 1 user before trying the amsoil and I've been using it ever since.

If you rilly listen to you engine it will tell you what it likes, while that may sound crazy to some people to me this stuff is definitely approved by my motor lol. It is good stuff a bit pricey but you will get what you pay for with this product there's no dought kn my mind.

Good for another year

I bought SS 5W-30 and a 15K filter for less than 4 oil changes

Simply the best stuff ever

Amazing products. Will not run anything else in my vehicles, atvs, snowmobiles.

BillV

When changing oil in a turbo engine the new formula Amsoil Signature series is a no-brainer!!

Best EVER!! BAR NONE

I was introduced to AMSOIL in 1989 and ever since then it's all I use. I've had dealerships and Auto parts houses try to sell me Royal Purple and Penzoil and Mobil One and I stop them before they even get going good. And I tell them, "Sorry that you like trashy oil in your prized possessions but as for me I only run the best, and that's Amsoil. It's been around since the 60's and it's never failed. So, why not use something that stands the test of TIME!!? That's why I use it, I "Know" it won't fail."

using amsoil for over 20 years.

Run it in every vehicle I own and my kids. Best product on the market

AMS oil signature 10W-30

Product is terrific. Improved engine idling & gas mileage. Good engine wear too! Shooting for 300k & beyond!

So far so good

Time in between changes

Great stuff !!!!!! I only use amsoil

Works great lasts a long time !!!! Over priced though

I won't use any other oil

We have a 2016 Honda Pilot and a 2014 Jeep Gtand Cherokee. The Pilot gets 28 mpg and the Jeep gets 24. I truelly believe it's because of AMSOIL. When we picked up my wife's Pilot from the dealer I told her that within 30 days i'll have it running so smooth that she won't know that it's running. She gave me the bonehead look. Long story short, both vehicles run as smooth as silk and the mpg's are higher since AMSOIL. Not long ago i got into her truck and i didn't know it was running. I asked her if she was going to start the truck before we leave for our trip. That's basically how the story goes for all of our cars; lawn equipment and anything that uses oil. It's the best you can get.

Yes

My vehicles definitely feels it has more performance.

Amsoil 5w30

Use in my Toyota Tundra since new 2006! 270,000 mi. Great protection, runs well & very consistent!

Excellant oil.

Use it in my 2000 Honda civic SI with 220000 miles on it. Still runs like a champ.

Mmmmm gooo

It's the best

Great product

Best synthetic oil in the world it's the best and only oil we use.

Great Product

This product is awesome, since I do not put many miles on my vehicles, with getting a Demo from work, it is nice to only have to change the oil in all of my vehicles once a year and know that it comes out as clean as new when I drain it! Superior product and highly recommend!

Signature Series 5w-40

Great oil, change it once a year. Been buying Amsoil since 1980, first as just a customer and then as preferred. I use only Amsoil oils, gear oils in tractor, small engines.

5w-30

Awesome oil! After changing the oil in my wife traverse to Amsoil everything has been running smoother. The only down side is sometimes my wife will start the car waiting for me to leave the house, I'll get in the car and try and crank it again because I cant hear the engine running it's so quiet now.

I've been with AMSOIL since 1988

I use it in my 2 wheel drive 4Runner and have 273,000 miles on the car all with AMSOIL.

Awesome oil

Amazing oil for the Toyota FJ. FJ ran better and oil at change interval didn't seem as dark.

I buy this product every year

Have been using in my last 3 vehicles

Even better than I thought

Works as designed; and extends oil changes intervals

Worked as designed

Gain in mpg and more miles/time before maintenance intervals

Get the quality your $$$ deserves Amsoil

I just changed the oil in both my rides and loves the quiet smooth sound when running my signature series.

I will not consider any other synthetic than the BEST.

I started using amzoil products before being called amsoil. I use the signature series oil and Eo and Eat filters. I change my oil once/yr. And I literally do not burn any oil in that yr. With my 00' tundra V8 using amsoil. My 02

Run with this oil for 30 plus years

Nothing on the market that beats it

I will buy this product again and again

This is the only kind of oil that I will use in my vehicles

I would buy this product and use it in every car I own

I own 2003 s2000 that I recently rebuilt the cylinder head on. Prior to the rebuild the car was turboed for a decent amount of time. The car currently sits around 112k miles at the moment after the rebuild. The car has been running Amsoil signature series for most of its life. When I inspected the camshaft, cylinder walls, etc during the rebuild the car showed absolutely no sign of wear anywhere and this is after being turboed and ran hard for a decent amount of time. I moved back to 10w30 signature series after the rebuild but still great stuff.

ONLY Amsoil!

I've taken several engines apart but only engines that have run Amsoil and they only need coolant system work. Conventional oil precipitates out garbage and sludges up engines resulting in CLOGGED oil passages. If your switching from conventional, get the best protection you can get that has tons of positive history. Do your homework/research to understand ALL the costs involved. You will determine Amsoil is the best switch you can make for your vehicles.

A Trusted Product

I have been using Amsoil products in my vehicles and motorized equipment for many years and relay on its quality. As a "gearhead", I know how important using quality motor oils and greases are to machinery. They are my first choice for lubrication fluids.

Only the BEST Oils for my vehicles

I only use American AMSOIL in all my vehicles. For this one, I use it in my 2005 Honda Fit 1500cc..

Only American

I only use American AMSOIL in all my vehicles. For this one, I use it in my 2016 Nissan Caravan NV350.

Great product

I run Amsoil oil and filter in my Yukon Denali 15,000 miles between changes. Just reset the change oil message at 7500. Doing this for years with several GMC Yukon's. At 250,000 plus miles no oil burn at all. Very impressed with not having to go under the car twice as much.

Best oil you can buy

Awesome cold start protection, and anti-wear lube, simply the best

Buy again

So far all is good.

I will buy this product again.

Why is it when I change my oil does my mileage drop by 2mpg. For the first 400 miles 1 1/2 to 2 mpg less then it creeps back up.

Great products

I have relied on Amsoil products for years to protect my engines and it has done exactly that.

Why change?

I started using AMSoil in the mid 80s while in Alaska. Cold extreme make lubrication very critical. At minus 40, most petroleum lubes won't even drip off the dip stick and when started cold you can hear every bearing in the engine as there is little or no lube flowing. No so with my AMSoil.

Not worth it.

I've been running 5W30 Signature Series in my 2002 Tacoma since putting it on the road in 2016 with 116,000 miles on the engine. I have since had Oil Analyzers (Amsoil, Inc.) test three samples from the truck so far, and have yet to have the oil last more than 13K miles before being told it's time for it to be changed. So much for the 25,000 miles/1 year claim...

This stuff is THE BEST!

I have 2 vehicles that have had this oil in them (changed every 15,000mi) since I bought them new. They both have mileage approaching 250,000, and they run like BRAND NEW. My newest vehicle is a 2017 Subie Forester Turbo so it gets Signature 5W-30 every 10,000 miles, and I'm sure it will see 200k and beyond.

Great product, well worth the money

Love the extended oil change intervals and my fuel mileage increased slightly, which leads me to believe it must be lubricating everything very well.

This is the only oil I will put in my engine

It's great year round hot or cold

Will Always use Amsoil

Several years ago I switched to Amsoil in my GMC Yukon. I was very impressed with what the Signature Series 5w-30 Motor Oil looked like after the first oil change. With all the oils and products that Amsoil offers, I have since switched everything I own over to Amsoil. Even my lawnmowers.

I can recommend this product

Used in my F150 exclusively. Excellent oil & filter.
Would not use anything else.

Great product!

I have used Amsoil for 30 years and wouldn't think of using any other oil.

Yes

Love that you don't have to change oil as offer as regular oil. Is is a little high. Hey but you get what you pay for.

Good stuff

I use Amsoil exclusively

The best synthetic oil

#1 for 3.5L ecoboost

This is the only oil I run in my Silverado Cobalt, and GTO

I like being about to change oil at any time between 5-10k and not have to worry about weather or not the oil is doing it job !!!

Amsoil always works!

I have been using Amsoil for over 15 years and have never had a problem, it's a well proven product that I trust in all of my cars for work and for pleasure. I will will continue to use Amsoil and benefit from it's proven results! I own a Livery/Limo Service and I drive about 40-50K miles a year on various cars and I believe Amsoil is the best Oil for all of my vehicles. With the long 15k Mile change intervals it is a money saving gem and your engine benefits 100%. I recommend there products highly!

SIGNATURE SERIES SYNTHETIC MOTOR OIL

I've used this brand and series in my Dodge Ram 4.7 v-8 since I acquired it at 90,000 miles. I've driven another 70,000 miles since and the engine is stronger than it's ever been! I expect to drive this truck until at least 300K miles because of the Amsoil Signagture Series Synthetic brand motor oil. I won't use anything else!

Great Stuff

I use Amsoil on my SUV and love it!

Great Oil

I use ansoil on all of my trucks, motorcycles, ATVs. This oil I use on 2017 Hemi 2500. It cannot be beat.

I love it

Instant satisfaction, after the first start up i could already hear and feel things running smoother.

Great Oil

This is the best oil money can buy in my opinion. I use this in all my vehicles and have for the last 12 years. Love only having to change the oil once a year. I highly recommend this product.

Best line out there

Bestboil products on the market by far. I run it in all my vehicles

No issues

I have used Amsoil products for many years in all of my vehicles and small engines. I have never had an issues. I recommend Amsoil even though it is not the cheapest but the delivery is very prompt.

Does what it promises.

Not sure about the oW-20 weight here in Florida, but that is what Honda calls for.

Good product

Always met my expectations.

Excellent products.

Using Amsoil in all of my family's cars. Using Signature series in cars that drive over 12,000 miles per year, and XL series in cars that drive less than 12,000 miles.
Sent a 27,000 mile sample for testing to a independent lab, and they recommended 30,000 miles next time based on the excellent results.
Also using Amsoil in all lawn equipment and for a standby generator.

I would definitely buy this product again

Great product gives better fuel mileage and cleaner oil after changes

The Best There Is

I've been using Amsoil since the 1980s in everything with an engine. And have bragged about it's benefits to anyone who'd listen.

Increase mileage

I get better mileage with Amsoil
I run my 4x4 very hard and Amsoil is doing a great job of keeping it running strong

Great results

My 2004 Silverado (5.3L V8) has had a steady diet of Amsoil since its second oil change. I have stuck to the 10,000 mile interval, using Amsoil Ea filters & Signature Oil. She's about to roll over the 200,000 mile mark, and I have had no engine issues. I use Amsoil Signature Synthetic Oil in all of my vehicles, and plan on keeping it that way.

great in the city

I'm city driving in a 4x4 Ford van and after my last oil change the oil was still in great condition after 15,000 miles. just used the cleaning solution so lets see how this improves engine longevity. really happy with all th products I have received.

The Only Oil I Trust

I use Amsoil Signature Series in both of my cars that are susceptible to burning oil. The 10W30 goes into my Honda S2000 and works great! Amsoil is the only oil I use in my motors and gearboxes, after trying out several different brands, I have found their quality to be of the best.

Top Notch

I use it in my Subie Forester and my silverado 1500. no problems ever!

Best stuff on the market

Yeah like to 25,000 my old changed

10K Oil Changes

I will never use conventional again. 10K mile Oil changes, or once a year. You cant beat the quality and value of this product. No dealer or mechanic can ever persuade my to change every 3k miles again!. Get you some!

Excellent

I personally believe that with the history of Amsoil and their pioneering spirit I am getting the absolute best product on the market. They have been doing this longer and better than anyone else for a long time.
Can't beat the best!

I have been using Amsoil for 8 years in all my cars

More mpg and better engine protection for all my engines

Improved MPG

Bought Amsoil for all of my cars so I wouldn't have to change the oil so frequently and for the protection it gives all of the internal moving parts. I've noticed an increase in MPG and smoothness when I drive.
2017 Civic Type R
2012 Pilot Touring AWD
1998 Civic EX

Love this product

I use this product in my Nissan Altima. I took the car to the shop for warrantee work they checked out the car so they could try to bill me to fix some thing, but came up with my oil was looking a little dark and might want to look into getting it changed soon. I told them I had it under control and thanked them, at that point i had 18,000 miles on the oil [not bad]. I swap filters every 5k and change at 20k, thats just me.

My wife drives over 100 miles / day and AMS saves me money.

I now use AMS in a My has powered equipment

The standard

I've been buying amsoil for 15 years. I've always been satisfied with all of the products and I've never had an oil related engine problem. Typically my mom goes up as well.

I recommend Amsoil to my friends and they buy.

Honestly there is no longer any reason not to. Synthetic oil is more expensive at your local Auto parts store.

I think I gonna buy this product again.

I think this is a great product, even I used the product only once. My only problem is the shipping. The shipping is really offset the total cost.

Review

Excellent product.............................

definitely will buy again

personal vehicle use, engine purrs like a kitten improved mileage

WORKS EVERYTIME

have been using for years now always works better then other oil brands that i have used and its just great only having to do it once a year

Excellent products

I've been using Amsoil since 2009 in all of my power equipment from cars, motorcycles, lawn equipment, snow removal, generators and etc. I won't use anything else.

Excellent Product

Of course anyone who has done any research on motor oils realizes that AMSOIL motor oils are superior to anything else on the market. I like all their products however I am upset at their recent price increases. I'm not sure why they continue to raise prices as the majority of us retired people never get a cost of living increases in our income. Please don't tell me it's R & D or material and labor increases to justify the increase.

Will continue using

I have used in my Chevy and Honda notice engine is much smoother and no oil consumption

Running in all my vehicles

So far so good. No problems. AMSOIL has came highly recommended from my research. I plan on keeping my vehicles for the long haul and it made sense to step up to a better oil for my 2015 silverado 1500 z71 and lexus rx350, both of which use the same oil.

Owner

Amsoil is great use it in everything I own.

Great oil

I have been useing amsoil for over 25 years I have zero problems with it I run it in every thing I have

Great value

I use. the product in my daily driver has improved gas mileage

Excellent Product

I have two 2015 Hondas. Accord and Pilot. I put the Amsoil Signature 0W-20 in both vehicles after the breakin oil. (5,000 miles). I now have 40,000 and 65,000 miles on each. I like to get at least 200,000 miles out of my vehicles and they have both done great. Note: I also sent the oil to a lab for analysis with the first three oil changes on both vehicles and had good results.

Why buy a cheap alternative for your most expensive asset?

I've been buying 100% synthetic oil since 1974. I've stuck with Amsoil the longest because of their never-ending commitment to research and product improvement. Living in Northern New England where my wife and I both commuted to work, I had no time to entertain cars NOT starting on a -10F work day. I wanted the snowblower to start up - ALSO using Amsoil synthetic - and the cars to start and go without any concern. No need to worry about possible damage on the first cold spin - doesn't occur with Amsoil synthetic and filters. MANY times I have experienced our cars starting and we being on our way while neighbors and friends had to be jumped or call AAA. Combined with P.i. Fuel Treatment to maximize fuel economy I feel like I'm completely covered. Never experienced a motor failure in ANY of my vehicles including two that we drove over 200,000 miles. Keep it up Amsoil! I'm a tough customer, but you've never let me down.

I love it!

I love this oil. My truck runs smooth and does great on long trips!

The best period.

I have a 2016 GMC Sierra cam, DoD delete and procharger. Change it every 5k just to be safe it being boosted and no issues at all. I love this stuff!!

Amsoil products review

Over the past five months I have purchased oil for three cars, transmission fluid for four cars, and engine flush for three, as well as bottle pumps for oil and transmission fluid. In the next month I will be purchasing oil and transmission fluid for two more vehicles. As you can see I'm impressed with Amsoil products so much that I keep buying them for family. It's important to take care of the vehicles that my loved ones drive, because if they break down the result can undesirable.

Yes

I use this product for maintenance oil changes.

less hassle than ordinary oil

The thing that attracted me to AMSOil was the long interval usage of their synthetics. Only needing to change the oil once a year won me over and Amsoil is suppose to better protect engines on start-up. That's important in cold weather. It is quite a bit more expensive than conventional oil, but thankfully a person only needs changing this oil yearly which ends up being cheaper in the long run.

you can,t beat amsoil 2 stroke racing oils

i sponser a motorcycle flat track racer and we get the best results with amsoil dominator.

Will always use amsoil

Have been using amsoil since I could drive a car and will continue to keep using it

Only oil for the smart and wise!!

Have used Amsoil exclusively on all our vehicles! Extreme cold winters do not take its toll as with other products. Of course now we use Amsoil in lawnmowers, leaf blower, snow blower and in our 1973 Deutz farm tractor.
We have a lot of $ money in our vehicles and this is our way of protecting our investments !

Good stuff

Great oil. Holds up really well in my turbo Civic - confirmed by UOA.

Best Oil Ever Made

All Signature Series Oils and Ea0 Filters are the very best ever created.

Worth it

Surely saved the engine of my 2018 Crosstrek during the sub 25 degrees temperature. Starting was smooth. Never felt that the engine was starved of oil. Very reassuring to know the best stuff is in there at every start.

My #1 auto oil!!

People line up to buy my used vehicles cause they no the love they get, oil being #1!!

Surprising difference in my 2017 Honda HR-V

I thought the synthetic oil used by my Honda dealer was acceptable. Then I performed my own oil change with Amsoil Signature Series 0W-20 + Amsoil EA-series oil filter at 14,000 miles. The difference was immediate. The engine is so quiet now that I have to look at the gauges to see if it is running. No more valve/rocker arm clicking at idle. Acceleration is noticeably improved especially when merging onto freeways, although I haven't timed it. Combined city/highway mileage has increased 2.5 mpg.

Very great oil, last very long.

This is a great motor oil and I plan to get a new version that I saw of it on amsoil.

#1 synthetic motor oil

Since back in 80s amsoil rep sold me on this oil. This is the best motor oil .

The best

Only oil I use for any engine I own. An investment worth the payout.

Smooth start

Used in 2017 Honda CR-V
Noticed easy starts in cold temps 10-0 improved fuel economy 1.2mpg
Love it

I will continue to use this oul

I put this in to my 2014 Subaru Forester and noticed my engine runs quieter and smoother, the boxer engine was none to pas some oil but not mone

Long time Amsoil user

I have used Amsoil previously on other vehicles and I currently use this oil on two different Jeeps I own.

I have purchased your products for years

I use your products for ALL my power equipment & am glad that I use them

Use this Oil

I use this oil in my pickup

The best engine oil period

I've used Amsoil for over 20 years! This is by far the best oil you can buy! The warranty speaks for itself!!!!

Buy this oil.

I've used AMSOIL for decades. It has saved me lots of $$$ in repairs.

Order comes prompt and correct

Bought 2016 Silverado changed oil and filter at 3000 miles to AMSOIL changed every time the light comes on to change I know it can go longer and that's great piece of mind I'm a contractor and my load is never light but it never lets me down

Good oil for VVT engines

I have had 2 vehicles that required 0w20 oil. Both vehicles had variable valve timing engines and the oil worked very well for them. It allowed easy cold starts and provided good fuel economy.

Keep-on-rolling

I bought my new 2008 Hyundia March 2008. In June 2008 I changed oil for first time miles 7240. I stared using Amsoil 0W20 and I'still using the sme oil, Amsoil 0W 20. Now the car 320337 miles and NO engine problems. I drive between 12,000 and 15,000 miles and change the filter and add a quart of Amsoil and I'm good for another 15,000 miles. I do routine basic maiintenance,but the engine has never been apart execpt for the timing belt.

great deal

this is an outstanding value. great lubrication great price! always recommend amsoil to everyone I meet.

Have been using A

Have been using Amsoil for 20 years. It only gets better.

Best synthetic oil period

Amazing stuff

Best oil I ever used

This oil is by far the best on the market. I have recommended it to all my family and friends.

Best products period

I have been using Amsoil in everything I own.They have all types of oil related products that are great!!

I trust this company AND this oil

I use this oil in my 2017 GMC Sierra. It exceeds the Dexos 1 requirement, that GM has dreamed up. Don't believe their hype this oil will work great in your rig.

The best oil on the market. Period.
