KEY: N = data do not exist; R = revised.

a Total fuel consumption is the sum of alternative fuels, gasoline, and diesel. Oxygenate consumption is included in gasoline consumption.

b The remaining portion of 85% methanol, 85% ethanol, and 95% ethanol fuels is gasoline. Consumption data include the gasoline portion of the fuel.

c Excludes gasoline-electric hybrids.

d Includes a very small amount of other ethers, primarily tertiary-amyl-methyl-ether and ethyl-tertiary-butyl-ether.

e Gasoline consumption includes ethanol in gasohol and methyl-tertiary-butyl-ether.

f Diesel includes biodiesel

NOTES

Numbers may not add to totals due to rounding.

Beginning with 2003 data, the methodology used to develop the estimates of alternative fueled vehicles (AFVs) in use and alternate transportation fuel consumption were changed.The data reflect this new methodology.
