PREMIUM FUEL?

All i have is header, intake, & exhaust. Does it benefit me to put premium fuel in my car over regular?

no not really. all the higher octane fuel does is resist detonation. u need it for forced induction only. u will not see any increase in performance or fuel economy with ur mods. save your money and get the regular.

My car actually does worst with premium. I don't know why. I tried it once and it seemed like it was slower and less responsive.

I know. It was always the good stuff, chevron, never costco, albertsons, or fred meyers. I hated the days when premium was $4+ gallon.

ummmmm Costco gas does = Shell gas

well it all depends on what your local suppliers are.
in most cases there are only 2 or 3 distributors of gas in your area...in which most cases your getting the same gas regardless of where you go.

its because premium/higher octane gas takes a lil more time to burn than lower octane gas.. Higher octane requirements on some cars are seen usually on higher performance cars or high output engines, its coz due higher compression or aggressive power output it makes the car more prone to knock/detonation.. As mentioned higher octane gas reduces chances of knock coz they burn a bit slower, reducing chance of preignition or uncontrolled combustion..

and oh premium gas usually have more additive that helps clean up your injectors/fuel system.. I say shell FTW
