So what can you use ethanol for? You can make BD with it, if you've got a decent way to remove it from the water... if not, you'll have to find a way to measure what the content of water and ethanol mixed is, and add in an amount equivalent to 100% of the ethanol that would be required to make the fuel. Later on, the water will wash out after you perform the glycerine exchange.

Ethanol will also run your lawn mower, if you mix in some lubricant, like 3 in 1 oil or even mineral oil. You'll have to retune the carb, though.

Hell, you could even re-brew the ethanol with some lubricant additives and set up a second carb to run the metro on it... you can change a carb in an hour, so when you get a full tank's worth of ethanol/lube mix, swap carbs and burn it up!

At 10%, you get a free tank for every 10 tanks, and it keeps you from throwing away $2.50 worth of usable fuel (plus other costs) for only the cost of retuning another carb and swapping it, plus extracting costs for the fuel.

How many miles to a tank of straight ethanol do you think you'd get if your engine was properly tuned for it?
