Since you’re going to be hearing “alternative fuel” on an increasing basis as we move forward on our march toward environmental consciousness, following is a brief overview of some of the more common alternative fuel types (in no particular order).

• METHANOL (M85) is made mostly from natural gas, but methods to produce it via fermenting biomass are on the increase. One of the advantages to methanol is its virtual transparency to the end user with fuel systems of cars and trucks requiring only minor modification. A disadvantage to M85 is that it is more caustic than gasoline and as a result special oil additives are necessary to protect engines.
• ETHANOL (E85) is basically grain alcohol that is produced by fermenting biomass. The most commonly used biomass is corn, but other methods such as brewery waste are being tested. As an alternative fuel source for motor vehicles the typical blend-ratio is 85 ethanol and 15 unleaded gasoline. An advantage to ethanol is that the mixture can be used by most gasoline engines and retail outlets are becoming increasingly popular. A disadvantage to E85 is its cost as compared to gasoline.
