Ethanol producers want five percent increase in gasoline

Ethanol producers want to boost the amount of ethanol that can be blended with gasoline.

They are asking the Environment Protection Agency to raise the ceiling on ethanol content from 10 to 15 percent.

But automakers say an increase could damage engines, fuel lines and emission controls.

Some even say the operation of everything from lawnmowers to motorcycles could be affected.

The the ethanol producers say it would not be harmful to cars, and lifting the cap would spur demand and help an industry reeling in bad economic times.
