I run Amsoil in the Mustang engine and trans. On our Harleys I run Amsoil in the engine/trans/primary. The bikes I noticed a huge difference in shifting and they seem to run cooler.

i have only used amsoil signature synthetic in all my cars since 2005.

i actually go a larger amount of track days than i think anyone i know on the same oil. i also get it analyzed at blackstone and it looks good. i had better pressure in track conditions than someone else i saw with data at lower temps and heavier oil even from redline.

it's not the cheapest but i am a big fan.

in a normal daily driver these days i'd probably just run the amazon stuff.
