My local airport fuel service sells 101 octane low-lead fuel. This fuel has no ethanol. I have purchased it in my own 5 gal. jug for use in my hit and miss old time engines. I have also tried it in my 428 FE engine. It seemed to work perfectly. One thing I did notice is that the exhaust pipe outlet became a light gray color vs the typical black color it exhibits with unleaded. I do not use the av gas in the Cobra as a normal fuel. I am fortunate to be able to get 93 octane Sunoco here so the added cost and risk to tote fuel is not worth the effort. The airport will NOT pump the av gas into a car. And 5 gal. is the max they will sell at any time. As I recall the av gas was a very pale blue color and had a great odor.
