Methanol is a very misunderstood alternative fuel. Many technicians and pseudo-automotive buffs equate methanol with ethanol. Another possible side effect of changing over to methanol blended fuels is the possible detergent action on an older vehicle's fuel tank and lines. In an extreme case, fuel filters could repeatedly clog until the system would be entirely cleansed of these contaminants. Presently, the manufacturing of methanol from natural gas is the most economic process.
Methanol has slightly more energy than ethanol.
Presently, this is the most common use of methanol. In this higher concentration level, special materials need to be used in a vehicle's fuel system to prevent deterioration of these parts. Like all alcohol, methanol will absorb water. New Transportation Fuels, American Petroleum Institute, Washington, D.C.-1991. The Automobile .
