*reply deleted*in addendum: higher octane gas will make your car run richer, which, if your supposed to run lower octane, will actually rob you of power in theory
P.S. Just read through some of the posts. Your all fricken looney for going into that much depth about it.
Bottom line, unless your doing a full tune and checking every single ratio of shiznit in your car each fill up the choice is yours lol. Use it or don't use it. Overall for a stock vehicle imo i don't think premium is worth it.
P.S.S. Ya know what, to hell with it not getting sucked into another one of these debates no sir. Not while it's drinking hour!!!
