Has anyone read about the engineering that when into the engine cycling? I have always been told that the worst thing you can do to an internal combustion engine is to start it since there is no oil pressure to lubricate the parts. The Prius does this so many more times per drive than any other car. When the engine shuts off there is no low oil pressure light, would the light come on if there was a problem with the engine running? Does the engine have a conventional oil pump or an electric one?
