EPA has waived a limitation on selling gasoline that contains more than 10 percent ethanol for model year 2001 through 2006 passenger vehicles, including cars, SUVs and light pickup trucks. The waiver, announced January 21, 2011, applies to fuel that contains up to 15 percent ethanol, known as E15.

On October 13, 2010, the agency approved a waiver allowing the use of E15 for model year 2007 and newer cars and light trucks, but postponed its decision on model year 2001-2006 cars and light trucks until additional testing was completed. The agency has now completed that testing and has decided to issue the waiver for those model years. EPA also announced that no waiver is being granted for E15 use in any motorcycles, heavy-duty vehicles or non-road engines because current testing data do not support such a waiver.
