John,
My experience is that on engines that have 8:1 or less compression,
regulat (87 octane) fuel seems to be ok. As the compression goes up,
however, octane requirement increases to the point where "pinging" will
occur. at this point it is mandatory to increase the octane of the fuel
so that the engine performs properly and is not damaged.
Octane can be increased by upgrading the fuel or adding octane boosters.
