91 octane will do NOTHING for your cars that are tuned for 87.

And anyways.... why would you guys WANT to pay more for gas?!!? I drive an SVT, with a REQUIREMENT to get 91+ and it friggin sucks! Paying 10 cents more at the pump than everyone else blows chunks!

All that advertising bulls*** "run your engine cleaner and get more power, bla bla" is a buncha crap!

Octane rating is basicaly just the fuels ability to delay detonation.

Put low octane gas in a high compression engine, the heat of the compression with make the gas detonate prior to spark due to its LOW octane (low ability to delay detonation) versus putting higher octane gas in a high compression engine. The gas will be able to withstand the heat generated by the high compression in the engine due to its HIGH octane (high ability to delay detonation).

Read up what octane ratings are and stop listening to bulls*** advertising. All the gas stations want to do is f*** you anyways, why listen to them? ;)

Here is wikipedias definition:

Quote:The octane rating is a measure of the autoignition resistance of gasoline and other fuels used in spark-ignition internal combustion engines. It is a measure of anti-detonation of a gasoline or fuel.

So why put a slow burning fuel, in a car that needs a fast burning fuel? logic people.... logic!!
