Customer Ratings & Reviews

Perfect oil for ALL GM V-8s in our area. No problems with lifters, main bearings, or rod bearings and maintains the Amsoil quality you know from them.

Other than the oil that came from the factory, this is the only oil my gen 6 Camaro has ever seen. Nothing but the best for her!

I’ve been using AMSOIL products in all my vehicles for years and never had any issues. Highly recommended, why take chances when you can get the best from AMSOIL.

It’s a great product and I like the delivery… it usually comes in a nice kit with gloves, windshield sticker, and was suppose to receive a tool which I didn’t, that’s my only complaint

This is my first time using this oil I have heard and read a lot of good things. I am very confident in this oil and it’s ability to protect my engine for many more miles to come.

Excellent performance ,improved fuel economy and no consumption in my 2021 Ram Hemi 5.7.

They rook!

Very good product

Great quality oil product!

Been using in my 2019 wrx since brand new. Have 150k currently and have zero consumption or leaks.

I bought a new late 24 Toyota Tundra. First thing I did was a break in oil and filter change at 500 miles. AMSOIL Signature 0W20 and AMSOIL Oil Filter. Every 4 to 5k.

Works great engine feels smooth

Best oil ever for my Toyota specifying 10,000 mile oil changes. I tested the Amsoil oil in it with an analyzer and it showed my oil life still had 20% life left with 12,000 miles on it. I decided to change the oil at 13,000 miles and tested the oil and it showed oil life at greater than 15% oil life left. Very pleased I can extend my change interval from 10,000 miles with confidence. Use Amsoil products in all my vehicles and equipment as it is the best out there.

Totally satisfied with the products and the science behind it.

I'm convinced that amsoil is the best oil you can buy

I trust Amsoil products.

Saw a 2mpg increase since switching from Amsoil. I’m never going back to any other competitor

Use this in the dodge dart we bought my son, what a difference in everyday performance

This is amazing stuff, First time user and never coming back. The first time was 80k and I thought started out with Amsoil High-mileage 5w30. After around 3-5 miles I notice that my engine was quite, really quite, so I took it on the highway, afterword's I was in shocked. I revved it up to 5.7k RPMs, spirited drive and I had to slow down. I don't have any leaks or burning oil but I thought I should tell you all that shear my experience. I'm changing to Amsoil Signature after 85k. Also changed Amsoil fluids, front/rear diff and brake fluid, next time I well change transmission fluid and transfer case fluid. 2020 EXPLORER ST
