Octane rating DOES NOT equal power. Cars with aggressive compression and/or boost just need it to prevent detonation. Your Prelude falls into neither of these categories.

You'll actually get MORE performance out of the lowest octane rating you can run (since it is less resistant to ignition). So save some money, make some power, and just run good ol' regular 87.

While this is true for the most part, there are cars that relize you are running a higher octane and actually advance the timing automaticly.
