Servicing your vehicle Use of a specific oil is mandatory for proper operation of flexible fueled engines throughout the warranty period and for validation of the extended service agreement. Oil change intervals must be maintained at the recommended intervals. Refer to the "Service Guide" for the service interval schedules. SPARK PLUGS The spark plugs used in the flexible fuel vehicle are different than those used in the gasoline-powered vehicle. This is necessary to prevent engine damage due to pre-ignition. Standard spark plugs must never be installed on the FFV engine, because disabling and expensive engine damage may occur. Proper spark plugs may be purchased through your dealer. The FFV vehicle recommended Motorcraft spark plugs part number AGSF-22PP, which is installed as original equipment, must always be used for all types of fuels. LONG-TERM STORAGE Due to the small amounts of corrosive impurities that may be found in Ed85, it is recommended that the fuel be switched over to 100% high-quality unleaded gasoline prior to long-term storage of your FFV. 12
