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.

After replacing the oil in my car with Amsoil products, the car runs noticeably smoother and I have actually seen a slight bump in MPG.

Love this oil been using it for years and my Lexus runs so smoothly since I switched it to Amsoil.

I used to use royal purple now this is my go to product Its one great oil and I use it in all my cars from 2020 GMC Denali to my BMW 528i suburban expedition mazda and friends vehicles

Only run amsoil!

With Amsoil products my trucks going to last a long long time

So far so good truck running better

I have used Amsoil for the entire life of my truck, it now has almost 145,000 miles and couldn't be happier. I change my oil and filter every 20,000 miles.
