Debate lingers over 15 percent ethanol gas blend

WASHINGTON - It's a dilemma for drivers: Do they choose a gasoline that's cheaper and cleaner even if, as opponents say, it could damage older cars and motorcycles?

That's the peril and promise of a high-ethanol blend of gasoline known as E15. The fuel contains 15 percent ethanol, well above the current 10 percent norm sold at most U.S. gas stations.

The higher ethanol blend is currently sold in just fewer than two dozen stations in the Midwest but could spread to other regions as the Obama administration considers whether to require more ethanol in gasoline.

As a result, there's a feverish lobbying campaign by both oil and ethanol interests that has spread from Congress to the White House and the Supreme Court.

On Monday, the Supreme Court rejected a challenge by the American Petroleum Institute, the oil industry's chief lobbying group, to block sales of E15. The justices left in place a federal appeals court ruling that dismissed challenges by the oil industry group and trade associations representing food producers, restaurants and others.

Tom Buis, CEO of Growth Energy, an ethanol industry group, hailed the decision as victory for U.S. consumers.

"Now that the final word has been issued, I hope that oil companies will begin to work with biofuel producers to help bring new blends into the marketplace that allow for consumer choice and savings," Buis said.

The API had argued that E15 was dangerous for older cars.

Putting fuel with up to 15 percent ethanol into older cars and trucks "could leave millions of consumers with broken-down cars and high repair bills," said Bob Greco, a senior API official who has met with the White House on ethanol issues.

The ethanol industry counters that there have been no documented cases of engine breakdowns caused by the high-ethanol blend since limited sales of E15 began last year.

"This is another example of oil companies unnecessarily scaring people, and it's just flat-out wrong," said Bob Dinneen, president of the Renewable Fuels Association.

The dispute over E15 is the latest flashpoint in a battle over the Renewable Fuel Standard, approved by Congress in 2005. The law requires refiners to blend increasing amounts of ethanol into gasoline each year as a way to decrease reliance on fossil fuels and lower greenhouse gas emissions that contribute to global warming.

An EPA official told Congress earlier this month that the agency does not require use of E15 but believes it is safe for cars built since 2001. -- AP
