We ran mobile one in supercat engines and it ate lifters up like crazy the engine builder called mobile 1 junk motorcycle oil. We switched to driven per his request and never had another failure.

I like Amsoil. Ive used it in all my toys, throughout the years... cars, boats, and motorcycles.

Won't hurt a thing. I used to run Amsoil in everything. Moved to Tennessee and have to pay excise tax on top of cost to have it sent here. So I did my homework. Switched to the Delvac 1300 Super. The Super Duty has almost 100k since switching. Zero issues. The motor doesn't know which is in it. The difference is in how fast it breaks down. I run the Delvac 7-8000 miles whereas I could run the Amsoil 25000.
