Another reason NOT to use E anything fuel.Also below 50F you can have a carburetor icing problem especially with ethanol fuel blends. I had my personal mower to freeze up @ 40F while mowing leaves one year. And I had much worst scare @70F when the small plane I was flying developed carb icing. Not fun when you over a large city with no place to land. Turn on the heater and hoped for the best as I work to the airport. Engine straighten out about two miles from the airport but I sit in the lounge for a while getting my nerves settled.
Might be but the aviation fuel I was using was non ethanol 100LL.Another reason NOT to use E anything fuel.
