Ford Super Duty (2018 year). Manual - part 83

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.

E142732

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 421).

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 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 329).

6. Remove the dipstick and wipe it with

a clean, lint-free cloth.  See Under
Hood Overview (page 331).

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 433).

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.

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 433). 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.

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

WARNINGS

Do not handle a hot oil filter with
bare hands.

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 114).

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 423).

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

Capacities and Specifications (page
433).

5. For diesel engines, you need to reset

the Intelligent Oil Life Monitor™.  See
Information Displays (page 114).

Engine lubrication for severe
service operation

The following conditions define severe
operation for which engine operation with
SAE 5W-40 API CJ-4 is recommended. Oil
and oil filter change intervals will be
determined by the Intelligent Oil Life
Monitor™ as noted previously.

•

Frequent or extended idling (over 10
minutes per hour of normal driving).

•

Low-speed operation/stationary use.

•

If vehicle is operated in sustained
ambient temperatures below -9°F
(-23°C) or above 100°F (38°C).

•

Frequent low-speed operation,
consistent heavy traffic less than
25 mph (40 km/h).

•

Operating in severe dust conditions.

•

Operating the vehicle off road.

•

Towing a trailer over 1,000 mi
(1,600 km).

•

Sustained, high-speed driving at Gross
Vehicle Weight Rating (maximum
loaded weight for vehicle operation).

•

Equipped)

WARNING

Do not dispose of engine oil or oil
filters in the household refuse or the
public sewage system. Use an

authorized waste disposal facility.

Do not clean or recondition the filter
element.

We recommend that you demand the use
of genuine Ford and Motorcraft® parts
whenever your vehicle requires scheduled
maintenance or repair. Use the correct
specification filter element.  See
Capacities and Specifications (page
433).

Note: Operating your vehicle without a filter
element or with an unapproved filter
element may result in damage to the turbo
charger or exchanger and could lead to
engine damage that may not be covered by
the vehicle Warranty.
