Engine Oil

I wish they had zinc/phos specs listed for Castrol Syntec 10w-40 since that's what I put in last May on the dyno. I've only driven the car a couple thousand miles since then, I'll probably change it again in spring just for giggles. I think 20w-50 might be a bit much for my car, though according to FP I have a race engine since I make 100bhp/liter lol.

They actually said anything that makes 100hp per piston is in race engine territory.
