KEY: PP = based on plans or projections.
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 Includes a very small amount of other ethers, primarily tertiary-amyl-methyl-ether and ethyl-tertiary-butyl-ether.
d Gasoline consumption includes ethanol in gasohol and methyl-tertiary-butyl-ether.
NOTE
Numbers may not add to totals due to rounding.
