Notes: I was under the impression that per seat mile, fuel consumption of modern aircraft high bypass engines was competitive to cars. 747 aircraft claimed 20seat mpg with 40 year old engines.

Having a STC for auto fuel in my 50 Piper Pacer, preignition was the most detrimental hazard followed by alcohol eating the rubber hoses. The difficulty with auto fuel is the variable octane batch to batch and the mass of odd chemicals added to the base fuel all of which is not posted on the pump. With a $30,000 USD replacement cost, you get careful really fast.
