Not to mention, that jerrycan refilling is a bit of a mess, and potential safety hazard. A lot of airfields even prohibit jerrycan refuelling on the ramp.
I agree. Unless mogas becomes directly available on the airfields, mogas isn't really a viable option. I see mogas as a great "fallback option", ie. if you're stuck somewhere w/no avgas options for hundreds of miles.
Mogas is available everywhere.
So is diesel btw. (good for the SMA's/Thielert-Centurion and probably the Austro as well)
