Also,your GM dealer has additives that will help correct andprevent most deposit-related problems.Gasolines containing oxygenates, such as ethers andethanol, and reformulated gasolines may be available inyour area. General Motors recommends that you usethese gasolines if they comply with the specificationsdescribed earlier. However, E85 (85% ethanol)and other fuels containing more than 10% ethanolmust not be used in vehicles that were not designedfor those fuels.Notice: Your vehicle was not designed for fuelthat contains methanol. Do not use fuel containingmethanol. It can corrode metal parts in your fuelsystem and also damage the plastic and rubberparts. That damage would not be covered underyour warranty.Some gasolines that are not reformulated for lowemissions may contain an octane-enhancing additivecalled methylcyclopentadienyl manganese tricarbonyl(MMT); ask the attendant where you buy gasolinewhether the fuel contains MMT. General Motorsrecommends against the use of such gasolines. Fuelscontaining MMT can reduce the life of spark plugsand the performance of the emission control systemmay be affected. The malfunction indicator lampmay turn on. If this occurs, return to your authorizedGM dealer for service.Fuels in Foreign CountriesIf you plan on driving in another country outside theUnited States or Canada, the proper fuel may be hardto find.
