Note: If the oil level is between the
maximum and minimum marks, the oil level
is acceptable. Do not add oil.
Note: The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km).
Adding Engine Oil
WARNING: Do not remove the
filler cap when the engine is running.
Do not use supplemental engine oil
additives because they are unnecessary
and could lead to engine damage that may
not be covered by the vehicle Warranty.
To top up the engine oil level do the
following:
1. Clean the area surrounding the engine
oil filler cap before you remove it.
2. Remove the engine oil filler cap. See
Under Hood Overview (page 331).
Turn it counterclockwise and remove
it.
3. Add engine oil of the proper viscosity
and grade that meets Ford
specifications. See Capacities and
Specifications (page 431). You may
have to use a funnel to pour the engine
oil into the opening.
4. Recheck the oil level.
5. If the oil level is correct, replace the
dipstick and make sure it is fully seated.
6. Replace the engine oil filler cap. Turn
it clockwise until you feel a strong
resistance.
Note: Do not add oil further than the
maximum mark. Oil levels above the
maximum mark may cause engine damage.
Note: Make sure you install the oil filler cap
correctly.
Note: Soak up any spillage with an
absorbent cloth immediately.
Engine lubrication for severe
service operation
The following conditions define severe
operation for which engine operation with
SAE 5W-40 oil which meets Ford
specification, WSS-M2C171-F1, is
recommended. Oil and oil filter change
intervals will be determined by the
Intelligent Oil Life Monitor™ as noted
previously.
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 421).
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.
