Octane rating measures only ONE thing, the resistance to pre-ignition or 'knock'
or 'ping'. Nothing more!!! It is measured in a test engine with a screw adjustable
piston in the top of the cylinder. The piston is screwed in, increasing the
engine's compression ratio, until knock occurs. Anything more than you need is
simply enriching the oil companies. The octane rating can be increased with
additives BTW.
