Formulations aside, my big concern with buying mogas from a podunk airport
tank is that the gas could be old and contaminated. This would be due to the
small number of planes that are actually set up to burn mogas. With 100LL,
you can feel a bit more assured that the fuel has a had a decent "turnover"
rate and the fuel is fresher and cleaner.

From a podunk airport all bets are off for any type of gas. My
mechanic is the manager of just such an airport. He installed a 12,000
gallon 100LL above ground self fueling setup a few years ago. He
sometimes doesn't buy gas for 7-8 months.
