The only vehicles currently approved by automakers to use E15 are flex-fuel models, 2001 model-year and newer Porsches, 2012 model-year and newer GM vehicles and 2013 model-year Ford vehicles. These approvals extend only to cars, light-duty trucks and medium-duty passenger vehicles (SUVs). The use of E15 is expressly prohibited in heavy-duty vehicles, boats, motorcycles, power equipment, lawn mowers and off-road vehicles."The sale and use of E15 should be suspended until additional gas pump labeling and consumer education efforts are implemented to mitigate problems for motorists and their vehicles," continued Bakewell. "Consumers should carefully read pump labels and know their auto manufacturer's recommendations to help prevent any problems from E15." AAA urges fuel producers and regulators to do a better job of educating consumers about potential dangers before selling E15 gasoline. This outreach should include a consumer education campaign and more effective pump labels, among other potential safeguards to protect consumers and their vehicles. AAA also recommends additional testing to conclusively determine the impact of E15 use on vehicle engines and fuel system components. At least eight gas stations currently sell E15 and that number is expected to grow, which means now is the time to suspend sales before more retailers begin offering the fuel. The EPA in June officially approved the sale of E15 after receiving a waiver request from producers interested in expanding the use of corn-based ethanol. Despite objections by auto manufacturers, the EPA approved the use of E15 gasoline in flex-fuel vehicles and 2001 model year and newer cars, light-duty trucks and medium-duty passenger vehicles and SUVs. This means that nearly half (112 million) of the vehicles on the road today are not approved by either the EPA or manufacturers to use E15. AAA urges consumers to follow the recommendations of manufacturers to truly protect themselves from voided warranties or potential damage.
