To provide cleaner air, all gasolines in the United States are now required to contain additives that w i l l 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 help clean the air. General Motors recommends that you use these gasolines if they comply with the specifications described earlier. Fuels in Foreign Countries I f you plan on driving in another country outside the United States or Canada,the proper fuel may be hard to find. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel wouldn't be covered by your wa1-ranty. To check on fuel availability, ask an auto club, or contact a major oil company that does business in the country where you'll be driving.
