In fact, vehicles are now available on the market that run on varying mixtures of ethanol and gasoline. In addition, vehicles burning ethanol have slightly more power than those burning gasoline. A disadvantage is that ethanol is currently more expensive than most other alternative fuels. And, like methanol, it can cause difficulty in starting a cold engine unless chemicals are added. Methanol Also known as wood alcohol, methanol is made domestically from natural gas, coal, wood, or fermented agricultural wastes.
Methanol has the advantage of providing fleet operators with flexibility.
Few engine modifications are required for engines to run on low concentrations of methanol. Compared with gasoline, methanol also slightly increases the power available. On the other hand, methanol has the disadvantage of being toxic and corrosive. Fuel supply systems must be designed to prevent people from being exposed to it. Mechanics must be trained to properly handle methanol systems, because the flame is invisible to the human eye.
