Toyota Previa Turbo engine question?

This vehicle has a supercharger. It is not a "turbo engine", to clarify - you only have one engine; the supercharger just acts to force air into the engine to produce more power. A supercharger without oil is a serious problem, but does not produce more power and acceleration. If you do find that your supercharger needs more oil, you add it in the fill hole at the top. It takes a total of 130 cc's of oil - special to the supercharger.
