Use the search feature. Plenty of threads on this... use Oil Weight or if you are trying to decide between synthetic and standard oil, search Synthetic Oil... those should give you the info you are looking for.

run anything you want, as long as it is oily.
Does that mean I can actualy put Mike's sheets right into the fill neck and the engine will run?
