Moly, HP additives, Lucas, teflon, X90, Any of these things you have used? Raising or lowering gear oil vis for a race? Engine oil viscosity, how far would you go? Do you think we could get by with a 5w-20 synthetic for the duration? 0w20? 0w15? Or do we play it safe since we really don't know much about the engine? I know teflon is a joke. The additive X90(I think that was what it was called[snake oil maybe]) seemed promising. What have you heard of or used?
