This is my two cents in responce to JAM1775's post. I was under the understanding, like a lot of people I think, for a long time that that higher octane=more power. I've seen a lot of discussion on this on some other boards that I visit, and this is what I've learned from people who seem to know what they are talking about. The octane rating is only the measure of the fuels resistance to pre-detonation. AND THAT IS IT. You actually will make more power running the LOWEST possible octane that your engine will tolerate without "pinging" on. So in other words if you are spending money on high octane gas or booster to get your octane up to 95 or 100 when your engine runs fine on 91 you are spending extra money for less performance. It must have to do with the way all of those octane boosters and high octane gas are marketed or something because A LOT of people associate high octane with more power.
