STARTING AND OPERATING 165 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 without MMT. Gasolines blended with MMT have shown to reduce spark plug life and reduce emission system performance in some vehicles. DaimlerChrysler Corporation 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 his/her gasoline contains MMT. MMT is prohibited in both Federal and California reformulated gasolines. In Canada, MMT can be used at levels higher than those allowed in the United States. For this reason, it is even more important to look for gasolines without MMT in Canada. 5
