Alternative Fuels And Fuel Additives

Alternative fuels are substantially non-petroleum based fuels, such as biofuels, which include ethanol blends and biodiesel. Federal mandates requiring a significant increase in biofuels production and use have spurred an increase in the number of retail facilities storing and dispensing renewable fuels such as ethanol and biodiesel.

Methyl tertiary-butyl ether (MTBE) and other oxygenates are types of fuel additives. Although widely used beginning in the 1980s through 2005, MTBE is generally no longer used. Fuel additives are added to gasoline during the refining process. MTBE and other oxygenates raise the oxygen content of gasoline and can enhance octane quality and combustion while reducing exhaust emissions.
