I guess I might push my crankshafts harder that others do.
I do not think I have ever heard on a synthetic oil for my favorite Nitro Fuel dragster at 7000hp, Wonder why?
Thank you for you compleytly pointless rant
Nitro Fuel drag racers do use synthetic oil. 75w oil mostly, about 5 gallons in a dry sump system that gets changed when they rebuild the motor after every run.
