91 Octane
Where I live, the highest octane I can find is 91. Do any of you experts know if that is high enough or do I need to add some booster to each tank? The car seems to run fine but I don't know if higher octane gas would make a difference in the performance. Will octane booster hurt anything in the long run? Any thoughts would be appreciated.
