a Includes a very small amount of other ethers, primarily tertiary-amyl-methyl-ether and ethyl-tertiary-butyl-ether.
b Gasoline consumption includes ethanol in gasohol and MTBE.
c Total fuel consumption is the sum of alternative fuels and traditional fuels. Oxygenate consumption is included in gasoline consumption.
KEY: MTBE = methyl-tertiary-buytl-ether; P = preliminary.
NOTE: Totals may not equal sum due to rounding.
