Automakers Seek Delay in Raising Ethanol Blend in Gasoline.

WASHINGTON -- Citing new test data, the auto industry says the federal government's plan to raise the amount of ethanol mixed into gasoline will damage cars and increase the amount of pollution they emit. The Environmental Protection Agency is expected to issue a rule in the next few weeks that would permit oil companies to increase the percentage of ethanol in automotive fuel to 15 percent, up from the current level of 10 percent, so they can meet E.P.A. quotas for renewable fuels.
