Product Description
Protects Against Engine Wear ![]() *Based on independent testing of AMSOIL Signature Series 0W-20, in ASTM D6891 as required by the API SN specification.
Protects Pistons from Low-Speed Pre-Ignition (LSPI)
Protects Turbochargers
Extends Drains: Protection Guaranteed Trusted by Professional Engine Builders![]() "When we use AMSOIL, I don't worry about a film breakdown or an oil breakdown - and the oil pressure is always consistent. We've tested oils back-to-back on the dyno in our shop and we're always able to make more power with AMSOIL." -Brett Bowers, Engine Masters Competitor and Professional Engine Builder Maximum Cleaning Power to Battle Sludge![]() Engine failures due to sludge are often caused by a plugged oil pick-up tube screen - the motor is effectively starved of oil. The Sequence VG Engine Test measures an oil's ability to prevent sludge. During the test, a Ford 4.6L engine is subjected to sludge-inducing conditions for 216 hours. The industry standard allows for 10 percent blockage before the motor oil fails the test. Signature Series produced a screen virtually free from sludge (see image). Its detergent and dispersant additives are so effective, Signature Series provides 90 percent better protection against sludge. • *Based on independent testing of AMSOIL Signature Series 5w-30 motor oil, in the LSPI engine test as required for the GM dexos 1® Gen 2 specification. • *Based on independent testing of AMSOIL Signature Series 5W-30 in the GM turbo coking test. • *vs. AMSOIL OE Motor Oil • *Based on independent testing of AMSOIL Signature Series 5W-30 in the ASTM D6593 engine test for oil screen plugging as required by the API SN specification. * All trademarked names and images are the property of their respective owners and may be registered marks in some countries.

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... Item Reviewed: Signature Series Motor Oils

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!

less hassle than ordinary oilThe 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.

Surprising difference in my 2017 Honda HR-VI 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.

Can't believe the governments lack of actionSince we changed to Amsoil the mpg has gone up 5 mile /gallon extra on average. Plus in winter it is easier to start with the vehicle being parked out doors, huge difference. Change oil less frequently we can put on 20,000 miles/year seeing how I am in accounting if you extrapolate that experience over the millions of vehicles in the US, we could as a country save a ton of oil in petroleum used to lubricate and better gas mileage, what if the government alone changed to synthetics, wow.

LOVE ITI used this oil in my 2013 Toyota FJ Cruiser, which I use as my off-road vehicle and my daily driver. Compared to the other most recommended oil in my community, I found Amsoil to perform better. You may ask how I know it performs better. Well, I have been working on my family's cars since I was 13, so for about 33 years. I live where temps range from wind chill of -20F to heat index of 115F, and some days in the year the actual high between two days will change 40F. So how do I know it performs better? I can hear it, and I can feel it. I know that sounds silly, but growing up with a car that broke down 40 times in the first 4 years that I had it, I became very in tune to the sounds and feel of vehicles. Amsoil engine oil made my engine run quieter (on a 40,000 mile engine) and smoother (feel it in the pedal and floor vibrations from the engine bay).

Amsoil works!This is the second time I have filled my 2012 Toyota Tundra Crew with 0W-20 synthetic. Even though it takes 2 full gallons for a fill up its well worth the time and cost.

Long time user of Amsoil productsI've used Amsoil for about 30 years now. Used cars and new. My first oil change in the new car gets the Amsoil, and never anything else after that.

One of my vehicles is a Subaru, which calls for synthetic right from the start. I used to let the dealer do the oil changes, including using their own preferred oil brand, but I swear, when I switched it over to Amsoil it actually runs smoother and quieter. I don't know how or why, but it is what it is! My sons and my brothers use it as well. same results. Item Reviewed: SAE 0W-20 Signature Series 100% Synthetic Motor Oil (ASM)
Newer Hondas love this stuff!Like title says! They do! I buy this stuff by the gallon case. We have 4 newer Hondas that use 0w20. I still change oil every 5000 miles. Honda and Amsoil say you can longer but my OCD won't let me go past 5000!!!! Item Reviewed: SAE 0W-20 Signature Series 100% Synthetic Motor Oil (ASM)

great productMy boss turned me on to this product and he's been using it for years in end. I always used synthetic oils in my trucks and cars but never used amsoil, I can already tell a difference in gas mileage and performance in my car since I converted to this product. Very satisfied !

Easy on line purchase, picked up at warehouse.Use it in my 2010 Prius, once a year oil change. Item Reviewed: SAE 0W-20 Signature Series 100% Synthetic Motor Oil (ASM)
So far so goodi was already using 0-20 in my Toyota and my Subaru, so I didn't really notice a difference in mileage. Oil analysis suggests the extended oil changes are easily doable, but I'll do another at 25000 to make me feel better. Swapping just the oil filter isn't bad at all........just not what I'm used to.

Plan on buying this for years.So far so good. Started using this as of 70,000 miles now at 110,000. I really like the once a year oil changes. I'd be interested in seeing an oil test. Item Reviewed: SAE 0W-20 Signature Series 100% Synthetic Motor Oil (ASM)

Anybody with a car, truck, cycle or boat needs AmzoilBeen using Amsoil products on 3 service vehicles for a 20 year period and received 256K on my truck, 278K on my passenger car and 146K on my motorcycle. I know these products had a lot to do with those totals. Wouldn't use any other Brand EVER! Item Reviewed: SAE 0W-20 Signature Series 100% Synthetic Motor Oil (ASM)
costPeople tell me they don't use amsoil because of the high cost. But if you change the oil at 30, 000 mile intervals like I do, it actually costs LESS than paying for an oil and filter change every 5, 000 miles. And changing the micron filters every 10 to 15 thousand miles is very easy to do, plus you are getting a much better product using a full synthetic oil and your car's engine will last a lot longer. That's why all Nascar drivers only use a full synthetic oil. That's why jet airplanes only use a full synthetic oil. The protection, even at extreme temperatures is unparalleled. I had a real estate client who operated a fleet of 18 wheelers. He was so cheap he would change the oil at 100, 000 intervals, but he would change filters and do oil analysis along the way. But, my point is if he could operate all those trucks on a 100, 000 mile oil change schedule, it's really no problem for a passenger car to change oil at 30, 000 mile intervals because unlike regular oil a synthetic does not break down. The key is to do the micron filter changes on schedule, which usually require you add ftom a half quart to a full quart of oil at that time.

Good productSo far I have good results and I am extending drain intervals top 10k miles even after towing 7500 pounds most of the engines life. Item Reviewed: SAE 0W-20 Signature Series 100% Synthetic Motor Oil (ASM)
excellent product that does what it claimsI have used this oil in my Subaru for a number of years. every oil analysis comes back exactly as I'd expect, and I'm getting nothing but great performance from the oil. per mile cost is never worse than the typical synthetic competitors and I prefer the conservative margin of error this oil affords me...

Reviewed by Fernando Paterson: Best 0w20 - Cheap insurance against engine wear0w20 are the lowest viscosity oils currently used for cars. The upside is better fuel economy due to lower drag, therefore less energy wasted to pump oil inside the engine. Item Reviewed: SAE 0W-20 Signature Series 100% Synthetic Motor Oil (ASM)
