Do not blend used engine oil with diesel fuel under any
circumstances.Blending used oil with the fuel will significantly increase
your vehicle’s exhaust emissions and reduce engine life due to increased
internal wear.
Many of the world’s automakers approved the World-wide Fuel Charter
that recommends diesel fuel specifications to provide improved
performance and emission control system protection for your vehicle.
Diesel fuel that meets the World-wide Fuel Charter should be used when
available. Ask your fuel supplier about fuel that meets the World-wide
Fuel Charter.
Diesel fuel conditioner
Additives that will improve fuel cetane numbers may be used to
verify/enhance fuel quality. Use Motorcraft Cetane Booster &
Performance Improver, PM-22-A (U.S.) / PM-22-B (Canada) or
equivalent. The customer warranty may be void from using additives that
do not meet or exceed Ford specifications.
Do not use alcohol based additives to correct fuel gelling. This may
result in damage to the fuel injectors/system. Use Motorcraft Anti-Gel &
Performance Improver, PM-23-A (U.S.) / PM-23-B (Canada) or
equivalent. The customer warranty may be void from using additives that
do not meet or exceed Ford specifications.
Note:This ultra-low sulfur formulation is designed to meet the emissions
standards for the 6.4L engine and is backward compatible as well (i.e.,
can be used in Ford 6.9L, 7.3L, and 6.0L diesel engines).
Fueling tips
If the engine fails to start in 30 seconds, turn the key to the off position
and wait 30 seconds before trying again.
Truck stops have pumps and nozzles designed for larger, heavy-duty
trucks. When refueling at truck stops: if the nozzle shuts off repeatedly
when refueling, wait 5–10 seconds; then use a slower rate of flow (don’t
depress the nozzle trigger as far).
If air is allowed to enter the fuel system (during fuel filter change or if
you run out of fuel) the engine will purge the trapped air as it runs. The
engine may run rough and produce white smoke while air is in the
system. This is normal and should correct itself in a short time.
An engine that suddenly becomes noisy or operates poorly after a fuel fill
could be using substandard fuel (i.e., high water content, low cetane
rating or gasoline in the fuel). Diesel fuel should be purchased from a
reputable station which sells a large amount of diesel fuel.

FUEL FILTER/WATER SEPARATOR
Fuel Conditioner Module (FCM - E-Series)
The vehicle is equipped with a Fuel Conditioning Module (FCM) located
on the driver-side of the vehicle next to the transmission case.
Water should be drained from the
module assembly whenever the
warning light comes on. The WATER
IN FUEL light will come on when
approximately 0.2 pints (100 ml) of water accumulates in the module. If
water level is allowed to exceed this level, the water may be passed
through to the engine and may cause FIE (Fuel Injection Equipment)
damage.
Horizontal Fuel Conditioner Module (HFCM - F-Super Duty)
The vehicle is equipped with a Horizontal Fuel Conditioning Module
(HFCM) located on the frame-rail under the driver-side floorboard near
the transmission
Water should be drained from the
module assembly whenever the
warning light comes on. The WATER
IN FUEL light will come on when
approximately 0.13–0.16 pints (60–75 ml) of water accumulates in the
module. If water level is allowed to exceed this level, the water may be
passed through to the engine and may cause FIE (Fuel Injection
Equipment) damage.
DRAINING THE HFCM AND CHANGING THE ENGINE AND
VEHICLE FUEL FILTERS
Your vehicle is equipped with two fuel filters; one is mounted on top of
the engine.On F-Super Duty,the second filter, inside the HFCM, is
mounted inside the frame rail under the driver-side floorboard near the
transmission.On E-Series,the second filter, inside the FCM, is mounted
on the driver-side of the vehicle next to the transmission case.On all
vehicles,both filters should be replaced at the same time. 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/or fuel injection system damage. Refer to theScheduled
maintenance guidechapter of this supplement for more information.
Refer toMotorcraft part numberslater in this chapter for the fuel filter
replacement part number. This part number includes filters and seals for
both the engine-mounted and frame-mounted filters.

Installation - both
The engine will not run properly if the fuel filter is not installed
in housing.
1. Install the new fuel filter and cap seal into the fuel filter housing.
Refer toMotorcraft part numberslater in this chapter for the fuel filter
part number.
2. Tighten cap onto fuel filter housing slowly, allowing fuel to soak into
the fuel filter element. Tighten cap until it contacts the housing.
Turn the ignition key to on for 30 seconds, then turn it to off. Do this a
total of six times in a row to purge any trapped air from the fuel system.
Replace the filter bowl O-ring with new seal (included in filter kit) every
time you service the filter.
After filter service, a no start or rough running engine may indicate that
air is entering the system through the filter bowl seal or drain. Make sure
the drain lever is pointing rearward and stowed against the HFCM case.
Using a fuel which has more than average impurities may require
the fuel filter to be replaced more frequently than the service
interval specifies.
ENGINE OIL
Checking the engine oil level
Because it is normal to add some oil between oil changes, check your
engine oil level each time you stop for fuel. To check the engine oil level
consistently and accurately, the following procedure is recommended:
1. Have engine at normal operating temperature (at least into the
NORMAL range on the engine coolant temperature gauge).
2. Park the vehicle on a level surface, then turn off the engine and open
the hood.
3. Allow at least20 minutesafter engine shutdown to ensure that the
oil contained in the upper parts of the engine has returned to the oil
pan.
4. Protecting yourself from engine heat, pull out the dipstick, wipe it
clean and reinsert fully.

•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.
