EPA backing off E15 fuel?

Engineering experts believe that sustained use of E15 could result in costly problems.


A AAA survey last year found that only 12 million out of the 240 million light duty vehicles on the roads were approved by manufacturers to use E15. Thirteen manufacturers stated that the use of E15 may void warranty coverage. AAA's automotive engineering experts believe that sustained use of E15 could result in costly problems such as accelerated engine wear and failure, fuel-system damage and false "check engine" lights in some cars. An overwhelming 95 percent of consumers surveyed by AAA were not familiar with E15, indicating a strong likelihood of consumer confusion leading to misfueling.

AAA believes that ethanol-blended fuels have the potential to provide motorists a clear choice at the pump that supports jobs, promotes energy independence and reduces fuel costs. Both E10 and E85 provide options for consumers at this point, and AAA would support a motorists' right to choose E15 once basic thresholds have been met regarding consumer protections. E85, which contains up to 85 percent ethanol, is designed for use by flex-fuel vehicles.
