A stripper, crakhead, midget (sorry, little person), dreamer, LBGTQ-RSTUV, recovering meth-head, ex-gorilla, helicopter mechanic, guy/girl/he-she/it I met once outside a spirit airlines unisex family bathroom recommended amsoil.

I have stayed away from amsoil ever since....

Only use Mobil 1, full synthetic since 1993 when GM mandated synth, and strongly suggested Mobil 1 for the C4 vette. Hummer purrrrs on it. My C8 new vette calls for it too.

For FL, I would go to 10w-40 from my usual 5W-30.

Forget the gimmick oils, the additives, etc. No long life oil. Change it when the H2 tells you to. And do not use crap filters.
