Damned if I know what would be considred high compression. Most indepth articles I read mentioned very little about a direct correlation between compression and octane. The focus was more targeted at what it takes for certain engines to fully utilize the energies of such fuels. The exception being race engines...
Wunna the best articles I read on this was in Motorcycle Consumer News. They ran DYNO tests with exhaust analyzers to determine what, if any advantage would be obtained by running high octane fuels in engines designed to run lower octane fuels...
The answer was suprisingly simple: No advantage unless you're engine was designed to burn the higher octane fuels. In some instances, horsepower had actually dropped by 1 or 2. They even went so far as to say that running high octane fuels in engines other than those designed for it could be depremental...
