after talking to a friend about oil changes, he suggest royal purple as its fully synthetic, wikipedia says its a group I oil unlike Mobil 1 which is a group III
not sure what that means, but the way wiki had it worded sounded like group one is better. It was only a brief paragraph on royal purple oil and its written by non pro's.
i was jus wondering if anyone else has had an experience w. royal purple
