Customer Ratings & Reviews

I’ve run Amsoil 5W Signature Series in my ‘21 Chevy Malibu since I bought it a year ago. I use this car to commute to work, traveling 160 miles daily on an interstate highway. The car has the 2.0 Ecotec engine for over 35k miles in the past year. The engine is turbocharged and a very good oil is need with that. I’ll continue to use the 5W-30 Signature Series in this car for as long as I own it. Amsoil makes superb lubricants and I’ll continue to use them. I also like that Amsoil stocks very high quality oil filters for my vehicles. Great product and seller. I’ve given them five stars and an A+

We run the 0W-20 in my son’s 2018 Toyota Tacoma pickup. The signature series exceeds Toyota specs for engine oil and we’ve been happy with the results. You can run this oil at extended drain intervals without fear of the oil degrading and breaking down. Great product that we 100% believe in. The engine runs quieter with this oil in the crankcase. I’ll give it an A+.

I’ve been running this 5w 30 in my drift car with crate ls3, after about 1,000 miles and a dozen events I did a cam swap. There are no visible wear marks on the stock cam after a ton of abuse. Run the 5w 40 in the 6.7 powerstroke, have noticed smoother and quicker start up’s.

I’ve been using Amsoil for years know, this is the best oil manufactured today. If you want the best engine protection use Amsoil.

I want thanks ams oil with there awesome and service and keeping me up to date too

I have been using AMS Oil in all 3 of my 6.4 hemis. AMS oil meets Chrysler specifications, but most oils do not even if it’s the correct weight oil. You do not want to damage your engine and have costly repairs. I use AMS oil and have had great success with it and perfect running engines. Do your research and request AMS OIL.

Amsoil is the best motor oil I have ever used.

Best oil I have ever used

In my opinion the best.

The best oil money can buy.

Amazing stuff

For over 30 years I have relied on AMSOIL products in all my vehicles. My vehicles have been everday drivers,10 Corvettes, pickup trucks, Ford Diesel used for towing with enclosed trailer, Drag Race cars, golf cart, lawn tractors and 2-cycle equipment, chain saws, large and small air compressors, air tools and anything else I could find that would benefit from the best in lubricants. Never have I had a problem due to a lubricant failure. You can always tell the difference when switching to AMSOIL.

Been using Amsoil for about 13 yrs in my Harley and my trucks. Performance always rises with amsoil inside.
