You got me in a corner and ya'll are correct will not get rid of ethanol, but will keep the gas and ethanol bonded.encapsulating water thus not allowing phase separation which is what is killing motors.
"Encapsulating" water is what ethanol does. Ever heard of dry gas? Thing is we don't want gas and encapsulated water to burn in an engine. Ethanol attracts water. Get rid of ethanol and you get rid of the water along with the other problems that ethanol causes like corrosion and damage to rubber parts. I would assume that the only way to separate ethanol from gasoline is to distill it but I don't know how that will effect some of the other desirable components.
