[QUOTE="jason6488, post: 14089639, member: 155294"] So first of all Octane is a fuel, like butane. It has a certain laboratory resistance to detonation. Gasoline is compared to octane and thats where the number system comes from. I don't remember the actual equation but it's not very complicated, can be looked up if you're that interested and I think is listed on the pump sometimes. Second, I'm no expert on gas station tanks, but I do know MOST have 2 tanks, like mach828 stated. They probably do this for economical reasons. It's possible however that the particular station you mention has 3, or more tanks and is simply catering to customers who want fuel with or without ethanol. A few stations still offer ethanol free gas for a variety of reasons and maybe your station just wants to cover all the bases? Either way, to chime in with EVERYONE else here, a car tuned for 87 octane doesn't make any extra power on 91 or 93 or whatever else you have. I will say on a technical note I think higher octane fuels have very, very, very slightly less power per unit of fuel because of the additives blended to allow the higher rating, but I might be wrong. It's been a while since I read about octane ratings and such. [/QUOTE]
