The only reason to run high octane fuel is to prevent detonation (knocking,
pinging, pinking...).
Put some regular gas in and listen while accelerating in fourth from low
RPM. If you don't hear any detonation, O.K.
If you hear detonation, try retarding the timing a little until it goes
away. If you can live with the loss of performance, O.K.
