Quote:It is a tuned turbo and yes it will run on reg but not well and will backfire a lot. High compression engines really do need premium. Imo gasoline manufacturers should just drop the three blends and just make a 91 octane everyone can use. You would be suprised the amount of vehicles that need premium now.
Your oil makes more of a difference than the fuel.
