A federal appeals court Friday threw out a challenge by automakers and other groups to a new fuel with a higher blend of ethanol that could damage engines.

The U.S. Court of Appeals in a 2-1 decision rejected a suit brought by Alliance of Automobile Manufacturers, Global Automakers, the Grocery Manufacturers Association, the oil industry and other groups that sought to overturn the Enviromental Protection Agency’s approval of E15 -a fuel that includes 15 percent ethanol.
