Don’t come crying to me when you need to drop your tank and replace your fuel pump. And your injectors. And lots of other things. Obama did enough damage to those of us who like older cars with Cash for Clunkers, and now this crap.

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 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.
