Performance/Gas Miliage For Premium?

[Blazing_Firebird]

Hey everyone-

I gotta go fill up my gas tank tonight, and I was just wondering...does premium give better gas miliage on F-Bodies or does it really not make a whole lot of difference.

That, but also, does the car perform at a higher functioning with premium than say regular?

Any help would be appreciated, as I dunno if using regular is worth it or not anymore.

V6 you want regular gas.

V8 you want premium.

You won't gain anything out of running higher octane. The lower the octane the easier it burns so you will do a lot better using the lower octane. This has been discussed to death. Try searching in General Tech.

Thanks for the advice.

Also...

I've heard there are better gas companies to purchase gas from than others...they have better gas or something.

Does anyone have a recommended station list? Or stations to stay away from because of problems?

Just stay away from Wal-Mart brand gas lol. I try to keep with one company. All gas companies put their own additive into the gasoline, I try not to mix all those additives. I try to always go to BP when I can. If not BP then Shell.

my car always ran the best and the best MPG on Shell 92 octane... not 91, not 93 but 92 :D

i get significantly better gas mileage with higher octane than with 87, if that's what your looking for...

depends on the mods you have on it. mods that will let u run lower octane: exhaust(headers, cat, cat-back), cooling system(radiator, thermo, coolant, ect.), colder spark plugs, ECM tuning to 87 octance, higher altitude(less dense air/fuel mixture), cold air intakes, tb spacer, basicallt anything that will reduce temps inside and around your motor.
