RE: How to remove water from fuel
Ross is right, water will not seperate from alcohol, even at freezing temperatures. In fact we have all done this experment when we put windshield washer fluid in our cars. It is a mixture of methanol, water, and soap. It will not freeze, unless maybe you drive to the Arctic. If you found a solid in a freezing cold jug of fuel, is was likely a mixture of oil and water. Castor oil will disolve a bit of water and the two will make a hard gel at the bottom of the jug. It turns into a whiteish color as well.
