I put Octane 94 in my RCF (no ethanol) and definitely I feel a difference in throttle response and midrange torque delivery compared to Octane 91. It also makes sense considering the very high compression of the engine, higher Octane resists heat better than lower Octane fuel upon compression in the cylinders.
