The stuff that is added to gasoline in winter for water problems is Methanol, while the chemical most recently foisted on the public for general use is Ethanol. Two different chemicals with very different properties!!

Methanol was once known as wood-alcohol, and is mostly derived from petroleum today. Ethanol is the "drinkable" stuff, if appropriately cleaned up. However it forms azeotropes with water and other chemicals and is difficult to keep moisture free. This is one of the reasons it has not been pipelined, but transported to mixing locations by rail car or truck. Another added expense when used as a fuel additive!
