Bingo. Hence why I said too much octane will cause a power loss. You only want to run as much octane as you need to keep knock away.

For instance, my sister in law's G5 is designed to run on 87 octane. If she were to put 93 octane in then the car would not be able to burn the fuel at the correct rate and therefor lose power.

The other myth about octane that annoys me is "93 octane burns cleaner" and along the same lines "It's good for the car and cleans it out to run a tank of 93 through it occasionally"
