Well it has happened. Local 100LL is $5.60/ gal and is not expected to
decrease. Is there anyone out there using Supreme MoGas in a Lycoming
0320
with 8.5:1 compression? If so what ignition timing changes were needed if
any?

thanks

I have an 0-320 clone from ECI 160hp with an Emag Pmag electronic
ignition. The ignition has a feature that allows me to switch between
maximum advance depending on the fuel being used. I believe it's a 4
degree difference but that's just from memory you might find some
usefull information poking around the emagair site. I haven't used any
mogas yet cuz I'm in a fuel co-op and right now 100LL is 7 cents a
litre cheaper than regular unleaded.
