a The remaining portion of 85-percent ethanol is gasoline. Consumption data include the gasoline portion of the fuel.
b May include P-Series fuel or any other fuel designated by the Secretary of Energy as an alternative fuel in accordance with the Energy Policy Act of 1995.
c Estimates for 2003, 2004, and 2005 are revised.
d Includes a very small amount of other ethers, primarily Tertiary Amyl Methyl Ether (TAME) and Ethyl Tertiary Butyl Ether (ETBE). Values are rounded to the nearest 100,000 gasoline-equivalent gallons.
e A replacement fuel is the portion of any motor fuel that is methanol, ethanol, or other alcohols, natural gas, liquefied petroleum gases, hydrogen, coal-derived liquid fuels, electricity (including electricity from solar energy), ethers, biodiesel, or any other fuel the Secretary of Energy determines, by rule, is substantially not petroleum and would yield substantial energy security benefits and substantial environmental benefits.
f Gasoline consumption includes ethanol in gasohol and MTBE. Diesel includes biodiesel. Gasoline and diesel values are rounded to the nearest million gasoline-equivalent gallons.
Notes: Fuel quantities are expressed in a common base unit of gasoline-equivalent gallons to allow comparisons of different fuel types. Gasoline-equivalent gallons do not represent gasoline displacement. The estimated consumption of neat methanol (M100), 85-percent methanol (M85), and 95-percent ethanol (E95) is zero for all years included in this table. Therefore, those fuels are not shown. Totals may not equal sum of components due to independent rounding.

Traditional Fuel Consumption: Energy Information Administration, Petroleum Supply Annual, Volume 1 (September 2007). Highway use of gasoline was estimated as 98.8 percent of consumption, based on data in the Transportation Energy Data Book: Edition 26, prepared by Oak Ridge National Laboratory for the U.S. Department of Energy (May 2007). Diesel consumption was adjusted for highway use by multiplying by .61 derived from Energy Information Administration, Fuel Oil and Kerosene Sales 2005 (December 2007). Diesel consumption was converted to gasoline-equivalent-gallons using heating values from the Energy Information Administration, Monthly Energy Review, (February 2008), Appendix A.
