Reviews of AMSOIL engine oil

I keep using AMSoil after seeing a test results sheet from Blackstone (i think thats the labs name) for my 6.0. Tested after 15k miles and was better than 400 mile motorcraft.

Amsoil Signature Series is all I have ever used, I will recommend it.

My preferred is Amsoil 10w30, the good stuff. Seem to burn less of it off when driving hard.

I run Amsoil small engine oil in my 2000 inverter.

Amsoil since day one, never let me down and improves mileage as well.

Amsoil Signature 5w-30

It’s probably placebo but I feel that I burn less with Amsoil. That said with current prices I’ve gone back to my default of Castrol.

O-w20 amsoil is top notch, expensive but worth it.

I use Amsoil in every vehicle with an engine that I own...this has not changed for 25 years. Amsoil is so good I'd pour it over pancakes if I ran out of syrup.

I'm using amsoil 5w30. Great product. Real synthetic. Superior protection.
