Mix mo & av
Deej: In my 9A with an O-360, I mix av with unleaded, ethanol free 87 octane mo in my rite wing for takeoffs and landings. Once I am at altitude and below 65% power, I switch to unleaded, ethanol free mo (no av) w/o a problem.
I'm paying a buck a gallon less for the unleaded, ethanol free, 87 octane mo. I have learned that unleaded, ethanol free 91 octane mo is only 10 cents per gallon more. We buy it in 500 gallon lots and it can only be used in airplanes.
Is anyone running 87 Octane mogas with a 160hp O320-E2D? I know 87 octane is fine with the 150hp O320-E2D with the 7.0:1 compression ratio. However, if upgrading an O320-E2D to 160hp 8.5:1 compression pistons, can you still safely use 87 octane, or are you now in the 91 octane realm? Thanks, -Dj
