•An engine block heater must be used at temperatures below
–10°F (–23°C).
•Use the same engine oil and filter change intervals when using
synthetic engine oil.
•Heavier SAE 15W–40 and SAE 5W–40 engine oils are
recommended for temperature over 50°F (10°C) and must be
used for heavy duty driving and trailer towing.
A symbol has been developed by the
American Petroleum Institute (API)
to help you select the proper engine
oil. It will be included on the oil
container you purchase. The top
section of the symbol shows the oil
performance by the API designation.
This should match the owner guide recommendation. The center section
will show the SAE viscosity grade

Changing engine oil and filter
Change your oil and filter according to thescheduled maintenance
informationin this supplement. Change more frequently if your vehicle
operation includes extended periods of idling or low-speed operation,
driving for a long time in cold temperatures or driving short distances.
See the following sectionEngine lubrication for severe service
operationfor all severe duty restrictions.
Refer toMotorcraft part numberslater in this chapter for the engine oil
filter part number. This filter protects your engine by filtering harmful,
abrasive or sludge particles and particles significantly smaller than most
available “will-fit” filters.
To replace the filter,
1. Unscrew the oil filter cap and wait a few seconds for the oil to drain
through the built-in drain valve.Note:The filter should be changed
before reinstalling the oil pan drain plug.
2. Reinstall and tighten the oil filter cap.
WARNING:Do not handle a hot oil filter with bare hands.
WARNING:Continuous contact with USED motor oil has caused
cancer in laboratory mice. Protect your skin by washing with
soap and water.
Engine lubrication for severe service operation
The following severe service operating conditions require unique engine
maintenance procedures:
•frequent or extended idling (over 10 minutes per hour of normal
driving).
•if vehicle is operated in sustained ambient temperatures below -10°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.
•towing a trailer over 1,000 miles (1,600 km)
•sustained, high speed driving at Gross Vehicle Weight Rating
(maximum loaded weight for vehicle operation)

•use of biodiesel, up to and including 5% Biodiesel (B5)
•use of high sulfur diesel fuel
If you are operating your vehicle under any of these conditions, change
engine oil and filter every 5,000 miles (8,000 km).
AIR FILTER RESTRICTION GAUGE AND AIR FILTER
REPLACEMENT
Air filter restriction gauge:
The restriction gauge, located on
the upper housing of the air filter
assembly, measures the vacuum
inside the air filter. The more the air
filter is restricted (dirty, clogged),
the higher the vacuum reading
Check the air filter restriction gauge
whenever the hood is raised to
perform general engine maintenance
at least every 7,500 miles (12,000 km). If the vehicle is operated in
extremely dusty conditions, check and reset the gauge at least every
500 miles (800 km), or two weeks, whichever comes first.
Change the air filter when the gauge reads near the “change filter” line
and the chamber is filled with yellow. Engine performance and fuel
economy are adversely affected when the maximum restriction is
reached.
Blowing-out the air filter element with compressed air is not
recommended as the compressed air may damage the filter paper.
Note:It is not possible to determine the level of filter clogging by visual
appearance alone. A filter which appears to be dirty may actually have
several thousand miles (kilometers) of life remaining.
Always use the underhood air filter restriction gauge to
determine when the air filter element needs to be changed. The
warning light on the instrument cluster should not be used
exclusively for determining when the air filter element needs
changing.

If you experience difficult starting, rough idling, excessive exhaust
smoke, a decrease in engine performance or excess fuel consumption,
perform the following checks:
•a plugged air inlet system or engine air filter element.
•water in the fuel filter/water separator.
•a clogged fuel filter.
•contaminated fuel.
•air in the fuel system, due to loose connections.
•an open or pinched sensor hose.
•low engine oil level.
•wrong fuel or oil viscosity for climactic conditions.
If these checks do not help you correct the engine performance problem
you are experiencing, consult an authorized dealer.
FUELING
WARNING:Do not use starting fluid such as ether or gasoline
in the diesel air intake system. Such fluids can cause immediate
explosive damage to the engine and possible personal injury.
If you fuel your vehicle at a truck stop, you may notice that the fuel
nozzle may shut off every 5–10 seconds. This is due to the flow rates
being designed for larger heavy duty trucks. You may have to fuel at a
slower rate (don’t depress the nozzle trigger fully).
Do not run your diesel vehicle out of fuel as this will allow air to enter
the fuel system which will make restarting difficult. The engine is
designed to run roughly as the fuel tank nears Empty. This is a warning
to the driver to add fuel as soon as possible. Longer engine cranking
time may be required once air is in the fuel system. If air enters the fuel
system (either through running the fuel tank(s) empty or during a fuel
filter change), the engine will self-purge the trapped air once it starts
running. The engine may run roughly and produce white smoke while air
is in the fuel system; this is normal and should stop after a short time.
MINOR TROUBLESHOOTING GUIDE
Air purge procedure
Turn the key on for 30 seconds, then turn off. Repeat procedure four or
five times.

Your Ford dealer, or Ford Quality Care Center has factory trained
technicians who can perform the required maintenance using genuine
Ford parts. They are committed to meeting your service needs and to
assuring your continuing satisfaction.
Protecting your investment
Maintenance is an investment that will pay dividends in the form of
improved reliability, durability and resale value. To ensure the proper
performance of your vehicle and its emission control systems, it is
imperative that scheduled maintenance be completed at the designated
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’s why it’s
important to rely upon your Ford 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.
Ford strongly recommends the use of genuine Ford replacement parts.
Parts other than Ford, Motorcraft or Ford authorized remanufactured
parts that are used for maintenance replacement or for the service of
components affecting emission control must be equivalent to genuine
Ford Motor Company parts in performance and durability. It is the
owner’s responsibility to determine the equivalency of such parts. Please
consult yourCustomer Information Guidefor complete warranty
information.
Non-Ford approved chemicals or additives are not required for factory
recommended maintenance. In fact, Ford Motor Company recommends
against the use of such additive products unless specifically
recommended by Ford for a particular application.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic of
the chemical compound and may not necessarily demonstrate that a fluid
needs to be changed. Oils and fluids identified in this guide should be
changed at the specified interval or in conjunction with a repair. Flushing

WHICH MAINTENANCE SCHEDULE SHOULD YOU FOLLOW?
Owner Checks and Services
Refer to Mileage Intervals for Additional Checks and Services
Certain basic maintenance checks and inspections should be performed
by the owner or a service technician at the intervals indicated. Service
information and supporting specifications are provided in theOwner’s
Guide.
Any adverse condition should be brought to the attention of your dealer
or qualified service technician as soon as possible for the proper service
advice. The owner maintenance service checks are generally not covered
by warranties so you may be charged for labor, parts or lubricants used.
