Has anyone looked at methods to get the ethanol back out of gas?  I'm thinking there must be some type of process. I know in making bio-diesel they 'wash' the fluid and then run it through seperators [or let it settle] to get the water back out. It sounds crazy but would it not be possible to do something similar w/ gas? I'm thinking some kind of little contained setup that a guy could dump is 5Gal can into, it runs through and seperates off the two. The ethanol could get disposed [I dunno.. in the lawn mower?] and the gas is off to the plane?  IIRC [not tested personally] we are the same in Central Canada in that the higher octane stuff doesn't have ethanol in it.

Would misting water into gasoline allow it to combine w/ the ethanol [I know it sounds totally crazy :) ] ??


I think the mechanism is that the ethanol helps the misted water MIX WITH the gasoline.  This is the chemical nature of mildly bi-polar molecules that makes the ethanol mixtures caustic to fiberglass tanks, where pure gasoline is just fine.

I think it would require a physical method to separate the two, probably distillation (and THAT is guaranteed to get your home insurance cancelled).
