A spokesman for Ford Motor Co. replied to EPM’s inquiry, saying, “We have approved E15 for use in all 2013 Ford vehicles including hybrids and Ecoboost.” Richard Truett added, “We are not retesting any older vehicles to see if they are compatible with E15 and we’re not commenting on the performance of E15.”
Basel referred to earlier testing done on E15 as part of an industry group in her comments: “GM as part of an industry group has performed a multitude of tests on 2001 and newer vehicles that are included in the EPA regulations for E15 and have found that damage to the vehicle's engines resulted. For model-year 2011 or earlier vehicles, we strongly recommend that GM customers refer to their owners manuals for the proper fuel designation for their vehicles. In fact, we recommend this across the board.”
