C) SINCE VALVE TIMING CONTROL DYNAMIC CYLINDER PRESSURE, WE CAN USE THE CAMSHAFT TO LOWER THE OCTANE REQUIREMENT. ENGINE DAMAGING DETONATION TYPICALLY OCCURS AT LOW RPM. THIS IS BECAUSE OF THE COOLING EFFECT FROM INCREASED CYLINDER ACTIVITY ABOVE 2,800RPM. THIS IS WHY WE USE CAMS WITH 240+ DEGREES DURATION @ .050" ON 110 LOBE CENTERS WITH 2,400 TO 2,800 STALL CONVERTERS TO SUCESSFULLY RUN ENGINES ON PREMIUM PUMP FUEL AT 11.0:1 COMPRESSION.
What I meant is plane fuel does not go bad like pump gas not so much the octane since you said you don't drive it often.
