Auto fuel is just good enough to do the job. Amoco's "crystal clear purity" is an interesting claim obviously targeted to the same gullible people who buy bottled water (and pay more than gasoline prices for it) thinking it is better for their health. "Pure what?" would be my question. Gasoline is a blend of hydrocarbons so it cannot be pure anything. My wife's horses generate "Pure" horseshit, which is what comes to mind at the moment. Amoco's slogan is not false in a Clinton sense, just meaningless. My "insights" came from several sources, one of them being a chemist at Chevron and the other the president of Daeco (specialty fuels). According to them, autogas is unsuitable for aircraft use due to variations in composition (and therefor combustion and evaporation properties) and the lack of controls on the distribution infrastructure. Automobiles are not littering the highway shoulders because they have good fuel filters, they have good mixture control (and sometimes knock sensors), they rarely operate at more than 50% of their rated power and are not operated above about 6 feet AGL. Think about when an automobile engine is likely to be detonating and then think about an airplane engine at takeoff. Thinking about the same thing?? Aircraft fuel does not travel in pipelines. There isn't enough of it going to a single place to warrant it. MoGas is not automobile gas from your corner service station without the road tax. It is handled just like aviation fuel from the time it leaves refinery. Any road tax savings is made up by this special handling and by liability costs. If you go to your local gas station to fill a drum with fuel and then use that fuel in your airplane, you are playing Russian Roulette, and eventually, you will loose. Can it be done? Sure. Is it a good idea? No way. I believe that the worst pilot is still an above average person in the general population so loosing a pilot is like gaining a politician. Pay a couple of extra bucks and live to tell stories to your grand children.
