Maintenance recommendations Oil change interval The engine oil should be changed every three months or 5,000 km (3,000 miles), whichever occurs first. If the engine oil is not changed as recommended, inaccurate oil readings and engine damage may occur. Oil filter change Use only an approved engine oil filter such as the Motorcraft Long Life type or an equivalent filter meeting Ford specification ES-E4EE-6714AA. Install a new oil filter at each oil change. Fuel filter To prolong the life of the fuel pump and ensure dependable fuel system performance, the fuel filter should be changed every 96,000 km (60,000 miles). This operation is not required, but is recommended for California certified vehicles. 11
