In general, to make max power, you want the lowest octane fuel that just barely keeps detonation away, and will lose power with any octane over that point. Detonation tends to start at lower RPMs and high loads, so you may be able to hear or feel it when cruising at a lower RPMs/speeds and opening the throttle significantly (heavy load).

I'm well aware of detonation. My Xc 250 detonates on most premium gas, but 93 octane from BP does not. I typically mix their 93 with some leaded 110 (VP).
