I understand that it may help if you run out of oil, but how many people with high performance vehicles or people that take care of their vehicles, run out of oil? I would be more inclined to by an oil that protects against slug and friction and what not then one that will help if you run out of oil. RP does not offer the best protection and like the review (I think we are thinking of the same one) says it does not provide the best protection. Therefore, to me, it is over rated.
