I just read in May 2009 issue of Model Airplane News on P 14, Augusto (Gus) Agner of Brazil removes the ethanol from his 20% gasohol just by adding water to his gas, and then emptying the fuel from the bottom (with a tube/siphon, or faucent type tap like coolers have I assume).

He writes that since the alcohol is attracted to water, both will combine and then rise above the gas after mixing.

This seems like a neat trick. I'm assuming one would then add the 2 stroke oil as normal AFTER separating the water/alcohol from pure gas. I guess the hardest part is finding a large clear container to do the mix and siphoning so you can see when draining when to stop so as to not get the water in your purified fuel.

If the gas manufactuers are purposely adding the alcohol, might they also add something else that may actually HARM the engines if burned in our motors WITHOUT the alcohol being there?

Any opinions?
