About E15 Fuel

E15 Gasoline

AAA has always supported the development and use of alternative fuel sources including ethanol/gasoline fuel blends. However, not all ethanol blends are the same. After extensive testing, AAA supports the use of the now widely available E10 blend since ethanol is a renewable, homegrown fuel alternative that can help advance U.S. energy independence. It can also be produced in large quantities and it needs less technology and infrastructure development compared to other alternative fuels. This ethanol/gasoline fuel blend is available in the state of Colorado.

AAA has expressed concern with the ethanol/gasoline fuel blend E15. AAA feels the sale and use of E15 should be stopped until there is more extensive testing, better pump labels to safeguard consumers and more consumer education about potential hazards. Growing repair evidence shows that if owners of older (pre-2001 model year), non-approved vehicles inadvertently use E15, it can result in significant fuel system problems. Even in vehicles approved by the EPA to use E15, research indicates reduced engine durability. Five manufacturers (BMW, Chrysler, Nissan, Toyota and Volkswagen) are on record saying their warranties will not cover fuel-related claims caused by the use of E15. Seven additional automakers (Ford, Honda, Hyundai, Kia, Mazda, Mercedes-Benz and Volvo) have stated that the use of E15 does not comply with the fuel requirements specified in their owner’s manuals and may void warranty coverage.

The fuel blend E15 is currently available in only a limited number of states, and is currently NOT available in Colorado.
