Very stable oil. Did quiet my 4Runner engine. No more engine stutter, hiccup or hesitation.

Watch all the real world tests, Amsoil is head and shoulders above the rest of the competition when it comes to synthetic oil performance. Worth every penny.

For me the best oil for new and old Cars. Its have the best protección to keep youre vehicle in exelent condition.

Never had cleaner oil when due for a change..spend the extra money now and save money later..all I have to say

great product

Been using Amsoil for the past several years, simply the best there is.

Makes better fuel economy

Awesome product, it's all I use

GREAT OIL FOR MY PPV CAPRICE. THE CYLINDER DEACTIVATION WORKS FLAWLESSLY! CLEANS ENGINE LIKE I HAVE NEVER SEEN

Great oil for the extended mileage capacity that my cross country fleet demands. No more California expensive oil changes that I used to pay for.

This is just simply the best on the market.

Running this oil in my 19' mustang, first oil change. Oil pressure runs higher now after getting the Ford MotorCarp oil out after 3300 miles.

I've used Amsoil for a number of years now. I currently use it in my 2018 Corvette, and 2006 Diesel Dodge truck that I tow with. Even though my annual mileage for both of these vehicles is under 7,500 miles per year I still change the oil every year. I also just flushed and refilled my Corvette with Amsoil's DOT 4 brake fluid.

This oil is great and I use it in my srt 10 ram. In between oil changes I have noticed less oil loss and it quieted my valvetrain down a little. Overall great oil and I would recommend to anyone looking for a top tier oil.

Way better than any other oil I’ve used. Lower temps (4-5°F) smooth start/shut off

Ive been using this oil and other Amsoil lubricants since the early 2000’s. Ive had oil analysis done many times and the test results are always great even at the oil change cycle. Ill always use Amsoil.

Great Oil

I love this oil I run it in my 2010 Lexus ES 350 and change my oil myself because I only want the best of the best in the engine

Good stuff, use it on all my cars.

I have relied on Amsoil Signature Series in all my vehicles for the past 7 years. 2 pickups, 5 cars, more than 1 million miles. I've never had a single oil-related issue in any of my vehicles, and I have complete faith in these products.
