AvGas is available at X price
MoGas is available at 3/4X price
Cost to re-refine MoGas Y (why is a good choice of letter)
Cost to repair damaged engine (each) $20,000.

Cost to repair damaged fuel tanks, plumbing, pumps and

Cost of FAA violation of regulations, certificate
suspension, a lot
Cost of uninsured aircraft when your insurance is cancelled,
priceless.

There is also the issue of performance. As I understand it, alcohol
doesn't produce as much horsepower per volume as does avgas. If I use a
mogas that has alcohol in it, I don't have the "Get up and GO" that I used
to have. On that hot day at high altitude, over an obstacle, which takeoff
performance chart do I use?
