5. For diesel engines, you need to reset the Intelligent Oil Life Monitor™. See
Information Displays
(page 113).
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).
• Use of fuels with sulfur content other
than ultra-low sulfur diesel (ULSD).
• Use of high-sulfur diesel fuel. CHANGING THE CRANKCASE
VENT FILTER ELEMENT
(If
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
432).
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.

Operating your vehicle in heavy snowfall
or extreme rain conditions may allow
excessive amounts of snow or water into
the air intake system. This could restrict air
flow and cause the engine to lose power
or shut down.
After installing a new air filter element, you
must reset the gauge by pressing the reset
button.
After operating your vehicle during heavy
snowfall or extreme rain, do the following:
•
Snow: At the earliest opportunity, open
the hood and clear any snow and ice
from the air filter housing inlet and
reset the air filter restriction gauge.
• Extreme rain: The air filter element
dries out after approximately 15– 30
minutes of driving at highway speeds.
At the earliest opportunity, open the
hood and reset the air filter restriction
gauge.
Note: Do not remove the foam filter.
CHANGING THE ENGINE-
MOUNTED AND DIESEL FUEL
CONDITIONER MODULE FUEL
FILTERS - 6.7L DIESEL WARNING
Do not dispose of fuel in the
household refuse or the public
sewage system. Use an authorized
waste disposal facility. Your vehicle has two fuel filters. The first
filter mounts on top of the engine on the
left-hand side. The second filter is inside
the diesel fuel conditioner module. The
module is attached to the fuel tank in
different locations depending on the
configuration of your truck. See table
below for configurations.
Note:
The module is at the front of the fuel
tank or at the front of the aft-axle fuel tank
on some models.
Regular fuel filter changes are an
important part of engine maintenance;
failing to keep with the scheduled
maintenance could lead to engine
performance issues and fuel injection
system damage. See Scheduled
Maintenance (page 581).
Use only recommended service parts
conforming to specifications. See
Motorcraft Parts
(page 422).
Note: Using fuel that has high levels of
impurities may require more frequent filter
replacements than the service interval
specifies.

When the oil change message appears in
the information display, it is time for an oil
change. Make sure you perform the oil
change within two weeks or 500 mi
(800 km) of the message appearing. Make
sure you reset the Intelligent Oil-Life
Monitor after each oil change. See
Oil
Change Indicator Reset (page 337).
If your information display resets
prematurely or becomes inoperative, you
should perform the oil change interval at
six months or
5,000 mi (8,000 km) from
your last oil change. Never exceed one year
or
10,000 mi (16,000 km) between oil
change intervals.
Your vehicle is very sophisticated and built
with multiple, complex, performance
systems. Every manufacturer develops
these systems using different
specifications and performance features.
That is why it is important to rely upon your
dealership to properly diagnose and repair
your vehicle.
Ford Motor Company has recommended
maintenance intervals for various parts
and component systems based upon
engineering testing. Ford Motor Company
relies upon this testing to determine the
most appropriate mileage for replacement
of oils and fluids to protect your vehicle at
the lowest overall cost to you and
recommends against maintenance
schedules that deviate from the scheduled
maintenance information.
We strongly recommend the use of only
genuine Ford, Motorcraft or
Ford-authorized re-manufactured
replacement parts engineered for your
vehicle. Additives and Chemicals
This owner's manual and the Ford
Workshop Manual list the recommended
additives and chemicals for your vehicle.
We do not recommend using chemicals or
additives not approved by us as part of
your vehicle
’s normal maintenance. Please
consult your warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a
normal operating characteristic and, by
itself, does not necessarily indicate a
concern or that the fluid needs to be
changed. However, a qualified expert, such
as the factory-trained technicians at your
dealership, should inspect discolored fluids
that also show signs of overheating or
foreign material contamination
immediately.
Make sure to change your vehicle ’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a
viable way to change fluid for many vehicle
sub-systems during scheduled
maintenance. It is critical that systems are
flushed only with new fluid that is the same
as that required to fill and operate the
system or using a Ford-approved flushing
chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals.
