NASCAR does NOT run the same engines! But that aside.. I know for sure the teams don't give a flip what is advertised on the car... they all use whatever oil they wish. Then they don't talk about it much.. Unless you are on the oiling part of the team you will have no idea what is in the engine...or tranny or rear end.. even the wheel bearing grease is secret execpt for a priviliged few..
