E-85 Usage In Non-Flex Fuel Vehicles

Non-FFV vehicles are compatible with gasoline containing 10% Ethanol (E10). Gasoline with higher Ethanol content may void the vehicles warranty.

If a Non-FFV vehicle is inadvertently fueled with E-85 fuel, the engine will have some or all of these symptoms:

operate in a lean mode
OBD II check engine light on
poor engine performance
poor cold start and cold driveability
increased risk for fuel system component corrosion

To recover from a Non-FFV vehicle inadvertently fueled once with E-85 perform the following: drain the fuel tank
change the engine oil
replace the fuel filter and oil filter
disconnect the battery to reset the engine controller long term adaptive memory

More extensive repairs will be required for prolonged exposure to E-85 fuel.
