Did you know: if you mix a quart or so of water in to each gallon of ethanol containing gasoline, the water and alcohol will separate leaving the gasoline alcohol free and dryer than when you started? You lose a couple octane numbers in the process, but now you have real gasoline. Adding a fuel stabilizer will give you a good end of season storage fuel.

"...if you mix a quart or so of water in to each gallon of ethanol containing gasoline..." Water doesn't compress.😎
