It probably is just a fluke, but there is a noticeable difference. It's primarily just slightly better throttle responsiveness, not an increase in horsepower.

Re: Octane Overkill
> Less energy is available per pound of gasoline run through the engine.
thanks. measure it any way you want. gasoline has the same energy regardless of octane. (and where on earth is gasoline measured by the pound?) this is perhaps the most fundamental constant in petroleum study. i will point this out once more for you Mr Shagnasty in case you are bitter at being told you are just wrong. all gasoline has the same energy per volume. always. period. octane is not a measure of energy. if you are unaware of this basic fact, you should not be posting advice about octane, rather you should sit in your chair, stare at your computer, and learn. now go, go. go away and play video games until mom calls you for dinner.

Quit top-posting. Do you dispute this sentence: "A gasoline with a higher octane rating will produce less BTUs when burned than a lower octane gasoline." If you do, then I *know* you're an idiot.

Gasoline is a mixture of a large number of components, and the mixture varies from grade to grade, station to station, week to week and from place to place. One example is that the winter formula with extra oxygenates contain several percent less energy pr gallon than the summer variety. Adding ethanol to gasoline will increase the octane rating and decrease the energy content. > > octane is not a measure of energy. if you are unaware of this basic fact, > you should not be posting advice about octane, rather you should sit in your > chair, stare at your computer, and learn. now go, go. go away and play > video games until mom calls you for dinner. > > "Elmo P.
