[QUOTE="COBRA90GT, post: 10165655, member: 2348"] Plus or minus [b]ONE[/b] horsepower. LOL The difference between 91 and 93 octane in a near-stock 2001 engine won't be anything close to 10-20 horsepower. As mentioned above, unless you have advanced the timing/tune of the car, all you are doing is wasting money by purchasing the 93 octane fuel instead of the 91 octane fuel (provided your engine runs just fine on the 91 stuff). Generally speaking, one would want to run the [b]lowest[/b] octane fuel in your engine that does [b]NOT INDUCE[/b] any detonation/pinging/knocking/etc. YMMV [/QUOTE]
