Does compression ratio effect octane requirements?

Yes, the higher the compression ratio, the more octane the fuel has to be. Anything over 10.0:1 has to be 91 or higher. However, if performance is not an issue, than you can use any type of fuel you want, but car will not accelerate fast and its torque curve will be very bad. Using low octane fuel in a high compression engine will also cause knocking (pinging, pinking). This will cause damage if continued.
