336 STARTING AND OPERATING Gasoline/Oxygenate Blends Some fuel suppliers blend unleaded gasoline with oxygenates such as 10% ethanol, MTBE, and ETBE. Oxygenates are required in some areas of the country during the winter months to reduce carbon monoxide emissions. Fuels blended with these oxygenates may be used in your vehicle. E85 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 E85 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 driveability • increased risk for fuel system component corrosion CAUTION! DO NOT use gasoline containing Methanol or E85 Ethanol. Use of these blends may result in starting and driveability problems and may damage critical fuel system components. Problems that result from using methanol/gasoline To fix a Non-FFV vehicle inadvertently fueled once with blends are not the responsibility of the manufacturer. E85 perform the following: While MTBE is an oxygenate made from Methanol, it • drain the fuel tank (see your authorized dealer) does not have the negative effects of Methanol. • change the engine oil and oil filter
