Fuels in Foreign Countries If you plan on drivingin another country outside the U.S. or Canada, unleaded fuel may be hard to find. Do not use leaded gasoline. If you use even one tankful, your emission controls won't work well or at all. With continuous use, spark plugs can get fouled, the exhaust system can corrode, and your engine oil can deteriorate quickly. Your vehicle's oxygen sensor will be damaged. All of that means costly repairs that wouldn't be covered by your warranty. To check on fuel availability, ask an auto club, orcontact a major oil company that doesbusiness in the country where you'll be driving. You can also write us at the following address for advice. Just tell us where you're going and give your Vehicle Identification Number (VIN).
