Customer Ratings & Reviews

Best there is

I never had a single lubrication/valvetrain issue since switching to this stuff

Excellent product

Great oil, car runs great

The product is of exceptional quality and the service is excellent.

I use the 0W-20 Amsoil Signature Series Synthetic Motor Oil for both our Cars.

Purchasing 3 new Twin Turbo Fords in the last couple of years thru investigation I switched directly to Amsoil from the dealer installed Motorcraft oils. I am a meticulous car person and keep vehicles for the long term.

Excellent, have used a few times now in a modified supercharged hemi 5.7. Working great thus far.

Good oil. Works great in my tundra.

I have been a dedicated Amsoil customer for quite some time. All of the independent studies I read confirmed a significant performance difference compared with other products.

Sure, it's great oil going in, but the magic is how well it comes out when it's done. This oil holds up better than anything. I use it in everything - daily drivers, weekend cars, etc
