If your vehicle is certified to meet California Emission Standards (indicated on the underhood tune-up label), it is designed to operateon fuels that meet California specifications. If such fuels are not available in states adopting California emissions standards, your vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be affected. The malfunction indicator lamp on your instrument panel may turn on and/or your vehicle may fail a smog-check test. If this occurs, return to your authorized Oldsmobile retailer for diagnosis to determine the cause of failure. In the event it is determined that the cause of the condition is the type offuels used, repairs may not be covered by your warranty. In Canada, some gasolines contain an octane-enhancing additive calledMMT. If you use such fuels, your emission control system performance may deteriorate and the malfunction indicator lamp on your instrument panel may turn on. If this happens, return to your authorized Oldsmobile retailer for service. To provide cleaner air, all gasolines are now required to contain additives that will help prevent deposits from forming in your engine and fuel system, allowing your emission control system to function properly. Therefore, you should not have to add anything to the fuel. In addition, gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area to helpclean the air. General Motors recommends that you use these gasolines if they comply with the specifications described earlier. I NOTICE: Your vehicle was not designedfor fuel that contains methanol. Don't use it. It can corrode metal parts in your fuel system andalso damage plastic and rubber parts. That damage wouldn't be covered under your warranty.
