There are a lot of " it depends" to answer that... An occasional can of
gasohol is not likely to do major damage if other gas in the tank is
diluting it... But, the best thing is to avoid the alky altogether.. Get a
glass column and test each time you get a fresh load from the station...
Easy and simple... Takes about two minutes... And if there is no change in
the height of the column of gas, then let the water settle out and carefully
decant most of the gas off the top and you won't be wasting but a teaspoon
of gas in doing the check..

My auto-fuel-stc says very clearly that one cannot use gasoline with
any type of alcohol in it. I understand that beyond the reg itself, the
main reason is that fuel lines can swell if they come into contact with
alcohol cutting of the flow of fuel to the engine.

I'm going to obey the reg (really. actually, honestly.). I'm just
curious.
How likely is alcohol to actually hurt or stop my engine or airplane?
