ENGINE OIL CHECK - 6.2L/6.8L
To check the engine oil level consistently
and accurately, do the following:
1. Make sure that your vehicle is on level ground. 2. Run engine until it reaches normal
operating temperature.
3. Make sure the parking brake is on. Make
sure the transmission is in park (P) or
neutral (N).
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.
5. Open the hood. See Opening and
Closing the Hood (page 329).
6. Remove the dipstick and wipe it with a clean, lint-free cloth. For 6.2L V8 See
Under Hood Overview (page 330). For
6.8L Triton
See Under Hood
Overview (page 333).
7. Replace the dipstick and remove it again to check the oil level. See
Engine Oil Dipstick
(page 334).
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
Capacities
and Specifications (page 419).
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.
Only use oils certified for gasoline engines
by the American Petroleum Institute (API).
An oil with this trademark symbol
conforms to the current engine and
emission system protection standards and
fuel economy requirements of the
International Lubricants Specification
Advisory Committee (ILSAC).
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. For 6.2L V8 See Under Hood Overview
(page 330). For 6.8L Triton See Under
Hood Overview
(page 333).
3. Add engine oil that meets Ford specifications. See
Capacities and
Specifications (page 419).
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.
