A common misconception that higher octane gives you more power. Octane is an ignition inhibitor that makes it harder to light gasoline on fire which is added to gasoline used in higher compression engines to prevent detonation (pre-ignition). Higher octane gas only helps if you have a higher compression engine (in the 13:1 range), so on a DLE-55, 92 octane is a waste unless the compression has been increased.
