Fiat Chrysler Automobiles (FCA) had approved the use of E15 (15 percent ethanol and 85 percent gasoline) in its model year 2016 Chrysler/Fiat, Jeep, Dodge and Ram vehicles.

According to the new owners manuals for the vehicles, “Non-Flex Fuel Vehicles (FFV) are compatible with gasoline containing up to 15% ethanol (E15).” The decision means that FCA joins General Motors and Ford in covering E15 in its warranty statements. GM started covering E15 with its MY 2012 vehicles, while Ford joined a year later with its MY 2013 vehicles. More than 12 percent of the vehicles sold so far in the United States in 2015 have been FCA vehicles.

“FCA’s decision to join GM and Ford provides clear evidence that the tide on E15 has turned,” said Renewable Fuels Association president and CEO Bob Dinneen. “FCA customers will be afforded a benefit that will likely lower their weekly motor fuel bill: the freedom to choose what fuel to put into their vehicles.”

RFA has been concerned about FCA’s reluctance to embrace E15 for the past three years, and Dinneen specifically called on Chrysler to approve E15 during his State of the Industry address at this year’s National Ethanol Conference.
