According to an analysis conducted by the Renewable Fuels Association (RFA) of 2016 model year (MY) warranty statements and owners manuals, auto makers are approving E15 use in more than 70 percent of new vehicles. This is an increase from MY 2015 when a little over 60 percent of vehicles were approved to use E15.

RFA’s analysis shows that, for the first time, Fiat Chrysler Automobiles (FCA Group) has approved the use of E15 in its MY 2016 Chrysler/Fiat, Jeep, Dodge, and Ram vehicles. FCA’s decision means it joins the other members of the “Detroit Three” (General Motors and Ford) in unequivocally allowing E15. Other key points from RFA’s analysis include:

• GM started approving the use of E15 with its MY 2012 vehicles, while Ford joined a year later with its MY 2013 vehicles.
• More than 45 percent of the vehicles sold in the United States this year have been produced by the Detroit Three, according to industry data.
• Other automakers offering explicit approval of E15 in MY 2016 vehicles include Toyota/Lexus, Audi/Porsche/Volkswagen, Honda/Acura, Jaguar, and Land Rover. Together with the Detroit Three, these manufactures have produced approximately 72 percent of the vehicles sold in 2015.
• When flex-fuel vehicles (FFVs) produced by Nissan and Mercedes-Benz are included, RFA estimates the percentage of MY 2016 automobiles explicitly approved by manufacturers to use E15 is even larger (FFVs are approved to use up to 85 percent ethanol blends).
• With a U.S. market share of 8.5 percent, Nissan Motor Company is the largest “hold-out” when it comes to approving the use of E15 in its vehicles. Nissan even goes as far as suggesting that “E-15 fuel will adversely affect the emission control devices and systems of the vehicle,” which raises questions about why Nissan is not able to provide the same quality of technology as automakers approving the use of E15. Curiously, Nissan also warns drivers that oxygenates like ethanol “can cause paint damage.”
• Hyundai, Kia, and Subaru also continue to exclude E15 from their fuel recommendations. Together, these three foreign automakers account for about 11 percent of U.S. auto sales. While Subaru recommends that gasoline used in its vehicles contain “no more than 10% ethanol,” it allows the use of gasoline containing 15% MTBE—a toxic substance banned in dozens of states because of groundwater pollution concerns.
• Interestingly, BMW’s MINI Hardtop appears to allow the use of 25% ethanol blends. The manufacturer states, “Fuels with a maximum ethanol content of 25%, i.e., E10 or E25, may be used for refueling.”

“This analysis should open some eyes and finally lay to rest the ridiculous myth that automakers do not allow the use of E15 in their vehicles,” said RFA President and CEO Bob Dinneen. “In fact, 2016 will be the fifth year in a row in which some auto manufacturers have explicitly included E15 in owners’ manuals and warranty statements as an approved fuel. With each passing year, more and more vehicles sold in the U.S. carry the manufacturer’s unequivocal approval for E15; and with each passing year, the auto warranty misinformation campaign undertaken by AAA and Big Oil fades further into irrelevance.”

Dinneen also noted the utter hypocrisy of statements made by AAA and the oil industry that using E15 may void auto warranties. “Ironically, not a single automaker approves the use of 85 octane gasoline, and the Department of Energy (DOE) warns that using such fuel may void warranties,” he said. “Yet, 85 octane gasoline continues to be sold all across the Rocky Mountain region and refiners are fighting tooth and nail to keep this inferior gasoline in the marketplace.”

While automakers began approving the use of E15 in their vehicles in 2012, approximately 6 million miles’ worth of testing by DOE and the Environmental Protection Agency (EPA) shows that the use of E15 is safe in all vehicles built since 2001. E15 waivers issued by EPA in 2010 and 2011 effectively approve the use of E15 in all vehicles built since 2001; this means more than 85 percent of the total current U.S. vehicle fleet can safely and legally run on E15.
