CHANGING THE ENGINE OIL
AND OIL FILTER
WARNING: Do not handle a hot
oil filter with bare hands.
WARNING: Continuous contact
with used motor oil has caused cancer
in laboratory mice. Protect your skin by
washing with soap and water.
If your vehicle is equipped with a diesel
engine, an Intelligent Oil Life Monitor
calculates the proper oil change service
interval. When the information display
indicates: OIL CHANGE REQUIRED, change
the engine oil and oil filter. See
Information Displays (page 112).
The engine oil filter protects your engine
by filtering harmful, abrasive or sludge
particles and particles significantly smaller
than most available will-fit filters. See
Motorcraft Parts (page 436).
1. Unscrew the oil filter and oil pan drain
plug and wait for the oil to drain.
2. Replace the filter.
3. Reinstall the oil pan drain plug.
4. Refill the engine with new oil. See
Engine Specifications (page 434).
5. For diesel engines, you need to reset
the Intelligent Oil Life Monitor. See
Information Displays (page 112).
