Changing the Engine Oil and the Oil Filter Change the engine oil and oil filter per the following, whichever occurs first. NOTE: Ford production and aftermarket (Motorcraft) oil filters are designed for added engine protection and long life. If a replacement oil filter is used that does not meet Ford material and design specifications, startup engine noises or knock may be experienced. It is recommended you use the appropriate "Motorcraft" oil filter (or another brand meeting Ford specifications) for your engine application. Refer to the Maintenance Schedule booklet for additional information. NOTE: Always dispose of used automotive fluids in a responsible manner. Follow your community's standards for disposing of these types of fluids. Call your local recycling center to find out about recycling automotive fluids. 219
