I'm sure some of our chemists here can confirm this. I'm considering getting a separatory funnel and stand to do this. Since ethanol attracts water all one needs to do is mix in a cup or more of water to a half gallon of E-10 or E15 gas, shake to mix well, then just let it sit for several hours. The heavier water/ethanol mix will settle to the bottom, while the nearly pure lighter gasoline will remain at the top. Then, in my plan, I would just let the water/ethanol mix out the bottom of the separatory funnel until only the gasoline remained. There would be an easily visible line of separation. The only thing holding me up at this time is what to do with the water/ethanol mixture.

It is still flammable and I don't know how I would get rid of it yet.

30 years ago we would have poured it on fire ant mounds.

If you use enough water to dilute the alcohol, the mixture would not be flammable.

Several lawn-mower mechanics recommend it too, especially if your lawn-mowers "sit" over the winter.
They start right back up in the Spring when I leave ethanol-free gas in them over the winter. Not so much with ethanol gas--something about the ethanol separating over time and doing bad stuff to the carburetors. Costs more but well-worth it.

Hmmm, I still don't think I could just pour it down the sink or flush it though.

For me it depends on the time of day. Morning fill up? Who has the best coffee? Mid day fill up? Which place has the best hot dogs. Late afternoon? Who sells beer the cheapest.

Putting ethanol in gasoline is the biggest fraud perpetrated on us by the agri-business industry and should be stopped.

Thank you for the tip!
