A symbol has been developed by the
American Petroleum Institute (API)
to help you select the proper engine
oil. It will be included on the oil
container you purchase. The top
section of the symbol shows the oil
performance by the API designation. This should match the owner guide
recommendation. The center section will show the SAE viscosity grade

Changing the engine oil and oil filter

Your vehicle is equipped with an Intelligent Oil Life Monitor™ that
calculates the proper oil change service interval. When the message
center indicates: OIL CHANGE REQUIRED, change the engine oil and
oil filter. See the Message center section of the Instrument Cluster
chapter for more information.
Refer to Motorcraft part numbers later in this chapter for the engine oil
filter part number. This filter protects your engine by filtering harmful,
abrasive or sludge particles and particles significantly smaller than most
available "will-fit" filters.
