The higher the gasoline's octane, the more additives it has so it does not combust cleaner than lower octane gasoline. Aviation gasolines have 104 or higher octane ratings. Tetraethyllead lead is still used in many aviation gasolines. Unless it is free, don't waste your money on expensive aviation gasoline for your Model A.

Have some fun with your Model A by running some of folklore fuels we hear about from the good old days. I ran my Coupe on home heating, alcohol and blends of both with gasoline. The heating oil made a stink, so my buddy Don would ride run behind me! Perhaps 151 Rum will work?
