Best oil for a solid flat tappit cam???

[Locomotion]

Amsoil has a wide variety of high zinc oils, including a new break-in oil, specifically designed for flat tappet cams that don't need additives. While additives say "compatible", the manufacturers may not know the specific composition of all oils and some may very well not be compatible. I would only use zinc additives when breaking in engines with newer oils and do buy the correct oil that doesn't require any "help". I use Amsoil 5w-20 Dominator in my race car.

I use recycled deep fryer oil in my car because it let's rev high and smells really good around lunch time.






JK Valvoline 10-40 but I'm all stock.
