Does the FAA allow ethanol in aviation gasoline?

Ethanol might be the cause of sealer failure.

The last time I heard ethanol is NOT allowed in aviation gasoline.

I wonder if Aviation gas has all of the Guberment (sic) mandated chemical makeup and junk that standard pump gas has..

That might be why there seems to be no problems with tank sealers in airplanes!

Just saying ...
