Servicing your vehicle required. Motorcraft engine oil (part number XO-5W30-QSP or XO-10W30-QSP or equivalent) is the recommended engine oil for these vehicles. Oil change intervals must be maintained at the recommended 8,000 km (5,000 miles) with either oil usage. If the vehicle is occasionally driven using methanol/ethanol blended fuels, the FFV engine oil (XO-10W30-FFV) MUST be used. The FFV vehicle recommended Motorcraft spark plugs stock number AWSFA-12C installed as original equipment MUST continue to be used for ALL types of fuels. 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. Ask for Motorcraft part number AWSFA-12C. At the time of this writing, no equivalent is available. For additional information, contact your dealer. FUEL FILTER The fuel filter used on flexible fuel vehicles is specifically designed using materials that are methanol compatible. Refer to the Service Guide for recommended intervals. When your fuel filter requires servicing, your FFV trained Ford dealer can install the proper replacement (Motorcraft part number FG-877). LONG-TERM STORAGE Due to the small amounts of corrosive impurities that may be found in M85 and Ed85, it is recommended that the fuel be switched over to 100% high-quality unleaded gasoline prior to long-term storage of your FFV. 18
