150 STARTING AND OPERATING fuel properties necessary to deliver enhanced emissions, engine performance, and durability for your vehicle. DaimlerChrysler Corporation recommends the use of gasolines that meet the WWFC specifications if they are available. Reformulated Gasoline Many areas of the country require the use of cleaner burning fuel, referred to as "Reformulated Gasoline". Reformulated gasolines contain oxygenates and are specially blended to reduce vehicle emissions and improve air quality. DaimlerChrysler Corporation supports the use of reformulated gasolines. Properly blended reformulated gasolines will provide excellent performance and durability of engine and fuel system components. Gasoline/Oxygenate Blends Some fuel suppliers blend unleaded gasoline with materials called 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. CAUTION! DO NOT use gasolines containing Methanol. Use of these blends may result in starting and drivability problems and may damage critical fuel system components. Problems that result from using methanol/gasoline blends are not the responsibility of DaimlerChrysler Corporation and may not be covered by the Limited Warranty. While MTBE is an oxygenate made from Methanol, it does not have the negative effects of Methanol. MMT in Gasoline MMT is a manganese containing metallic additive that is blended into some gasolines to increase the octane number. Gasolines blended with MMT offer no performance advantage beyond gasolines of the same octane number
