sure the transmission is in park (P) or
neutral (N).
2. Run engine until it reaches normal operating temperature.
3. Make sure that your vehicle is on level ground.
4. Switch the engine off and wait 15 minutes for the oil to drain into the oil
pan. Checking the engine oil level too
soon after you switch the engine off
may result in an inaccurate reading.

Under
Hood Overview (page 349).
7. Replace the dipstick and remove it again to check the oil level. See
Engine Oil Dipstick
(page 352).
8. Make sure that the oil level is between
the maximum and minimum marks. If
the oil level is at the minimum mark,
add oil immediately. See
Engine Oil
Capacity and Specification (page
449).
9. If the oil level is correct, replace the dipstick and make sure it is fully seated.
Note: Do not remove the dipstick when the
engine is running.
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 349).
Turn it counterclockwise and remove
it.
3. Add engine oil of the proper viscosity and grade that meets Ford
specifications. See
Engine Oil
Capacity and Specification (page
450). 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.
