Customer Ratings & Reviews

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.

Great Product

Excellent product

this is the only oil i will use

I use Amsoil products in every vehicle I own. They have never let me down

I've been using Amsoil Synthetic Oil for many years and my gasoline engines just keep going.

Vehicle runs better than ever on this product.

Great product it's the only oil I use in my 2016 RAM 2500 6.4 liter performs great.

I’ve used Amsoil products for 20+ years and I consider them to be excellent lubricants. I’ve used the products both gasoline and diesel engines and have never suffered an engine failure while using Amsoil oils. I currently use 0W-20 in my 2020 Subaru Forester, and I’m pleased with the performance and protection this oil provides.

Amsoil signature is the only stuff I will use, always holds up to whatever you throw at it.

This is all I use now. I've seen the cleaning power work. Sounds quite. Must try for yourself. Product is worth the money. But if price goes up to much poor people like me will have to stop using.

Since using the oil I gained mpg and much easier startup at -55 Ferenhight as well as cooler temps in the summer. Best oil ever

Excellent oil and reliable for higher mileage

Only oil I use on my evo x

I have been using Amsoil for years I feel safe that I won’t be having oil issues on My trucks and automobiles. Even plan on using it on my new Porsche

Best Oil I ever used.25,000 mile change and it still looks like new.

I always use amsoil in all my cars. I just trust the oil and never had any issues with it. I'll continue using it in the future.

I have been using this product in my 99 35th Anniversary Mustang since it was new. 👍

This oil increased fuel mileage and decreased oil consumption on my 2012 coyote mustang with 127k miles, it’s now my go to oil for my car, worth the price for increased efficiency
