STARTING AND OPERATING 309 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 "Malfunction Indicator Light" on • poor engine performance • poor cold start and cold drivability • increased risk for fuel system component corrosion To fix a Non-FFV vehicle inadvertently fueled once with E-85 perform the following: • drain the fuel tank (see your authorized dealer) • change the engine oil and oil filter • disconnect and reconnect the battery to reset the engine controller memory More extensive repairs will be required for prolonged exposure to E-85 fuel. MMT In Gasoline MMT is a manganese containing metallic additive that is blended into some gasoline to increase the octane number. Gasolines blended with MMT offer no performance advantage beyond gasolines of the same octane number without MMT. Gasolines blended with MMT have been shown to reduce spark plug life and reduce emission system performance in some vehicles. The manufacturer recommends using gasolines without MMT. Since the MMT content of gasoline may not be indicated on the pump, you should ask your gasoline retailer whether or not their gasoline contains MMT. 5
