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 vehicle’s 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.
