ENGINE OIL CHECK - 6.7L
DIESEL

To check the engine oil level consistently
and accurately, do the following:

1.

Make sure the parking brake is on. Make
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.

5. Open the hood. See Opening and

Closing the Hood (page 186).

6. Remove the dipstick and wipe it with

a clean, lint-free cloth. See Under
Hood Overview (page 188).

7.

Replace the dipstick and remove it
again to check the oil level. See
Engine Oil Dipstick (page 190).

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 261).

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 188).
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 261). 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.
