Topic: what oil are you guys using?
We've been using Rotella T6 for the cooler races and it gets pretty thin. For the hot stuff, I'm thinking we'll need something a little more robust. Cheap is key since it's going in a $500 car after all. Really don't want my oil bill to exceed the price of the car. Valvoline VR1 20w50? Tree sap? WD40?
