recommended oil FORD SUPER DUTY 2008 2.G Diesel Supplement Manual

•On F-Super Duty vehicles (6.4L engine),a frame-mounted
Horizontal Fuel Conditioner Module (HFCM)
•an engine-mounted secondary fuel filter
•a unit injector for each cylinder
The FCM/HFCM acts as a primary fuel filter/water separator which
removes both water and impurities from the fuel. The engine-mounted
fuel filter and the FCM/HFCM filter should be changed at the
recommended service interval. Refer to thescheduled maintenance
informationin this supplement for more information.
The FCM/HFCM should be drained at regular intervals or when the
WATER IN FUEL light illuminates in the instrument cluster (E-Series) or
when the WATER IN FUEL message appears in the message center
(F-Super Duty).
The fuel injectors are located in the center of the combustion chambers
in the cylinder head between the rocker arm assemblies. The glow plug
system and fuel injection system are controlled through the Powertrain
Control Module (PCM) and Fuel Injection Control Module (FICM) (6.0L
engine only).
Fuel is drawn from the fuel tank by a frame-mounted electric fuel pump.
The fuel pump provides pressurized fuel to the engine and is
electronically controlled by the fuel pump PCM relay. The fuel pump
contains a pressure relief valve for overpressure protection in the event
of restricted flow.
Engine protection mode
Ford diesel engines are equipped with engine protection and emission
control systems. These systems monitor critical temperatures and
pressures and modify engine operation accordingly. These features are
intended to modify engine performance characteristics. If these modified
engine performance characteristics persist for an extended period or the
Check Engine (
) or Powertrain malfunction/Reduced
power/Electronic throttle control light (
) is illuminated, seek
service from your authorized dealer.
Lubrication system
Extended oil change intervals can negatively affect engine performance,
fuel economy and engine life. Refer to the engine oil specification chart
located underEngine oil specificationsin theMaintenance and
Specificationschapter of this supplement.

On E-Series vehicles (6.0L engine),it is important to change the
engine oil at the recommended service intervals, because oil viscosity is
important in maintaining the oil pressure required to actuate the fuel
injectors.
On F-Super Duty vehicles (6.4L engine),it is important to change
the engine oil at the recommended service intervals to maintain oil
viscosity with the addition of the Diesel Particulate Filter (DPF)
Fast start glow plug system
The glow plug system consists of:
•eight glow plugs
•the glow plug control module (GPCM)
•engine oil temperature (EOT) sensor
•barometric pressure (BARO) sensor
The glow plug system is
electronically controlled by the
PCM. The GPCM energizes the glow
plugs immediately after the ignition
is placed in the ON position, then determines how long the glow plugs
will be on according to the EOT and BARO sensors. The required time
for the glow plugs to be energized decreases as the engine oil
temperature and barometric pressure increase.
Engine cooling system
The engine cooling system contains an engine oil cooler which is
mounted in the center valley of the engine. The cooler’s function is to
regulate engine oil temperature.
Fuel and turbocharger cooling system (F-Super Duty only)
The fuel and turbocharger cooling system contains a cooler which is
mounted on the turbo interstage U-tube on the left side of the engine.
The cooler’s function is to regulate engine fuel temperature and cool the
electronics that support the turbocharger. You may hear the auxiliary
coolant pump running up to 10 minutes after the ignition is turned OFF
in hot weather or if you are towing heavy loads. This is to control the
temperature of the turbocharger.

STARTING THE ENGINE
Read all starting instructions carefully before you start your vehicle.
For temperatures below 32°F (0°C), the use of the correct grade engine
oil is essential for proper operation. Refer toEngine oil specifications
in theMaintenance and Specificationschapter for more information.
If your vehicle is equipped with a manual transmission,make sure
the parking brake is fully set before you turn the key. Depress the clutch
pedal and place the gearshift in the neutral position. The clutch must be
fully depressed in order to operate the starter. Do not press the
accelerator during starting.
If your vehicle is equipped with an automatic transmission,ensure
the gearshift lever is in P (Park) and the parking brake is fully set before
you turn the key. Do not press the accelerator during starting.
Engine-driven cooling fan (Fan clutch)
Your vehicle is equipped with an engine driven cooling fan drive (also
called a fan clutch). This fan drive changes the fan speed to match the
vehicle’s changing cooling air flow requirements. Fan speed, fan noise
level and fuel consumption all will increase based on the driving
conditions that include trailer towing, hill climbing, heavy loads, high
speed and high ambient temperature, individually or in combination. The
fan drive is designed to provide the minimum fan speed (and resulting
fan noise and fuel consumption) required to meet the ever changing
vehicle cooling air flow requirements. You will hear the amount of fan
noise increasing and decreasing as the engine power requirements and
vehicle driving conditions change as you drive. This is to be expected as
being normal to the operation of your vehicle. High levels of fan noise
might also be heard when your engine is first started, and should
normally decrease after driving for a short time.
Cold weather starting
It is recommended that the engine block heater be used for starting
when the temperature is -10°F (-23°C) or colder. Refer toUsing the
engine block heater (if equipped)in theDrivingchapter of the
Owner’s Guide.
When operating in cold weather, use a minimum of 45 Cetane Diesel fuel
or use Cetane improvers from a reputable manufacturer.
Do not crank the engine for more than 30 seconds as starter damage
may occur. If the engine fails to start, turn the key to 3 (OFF) and wait
30 seconds before trying again.

Do not use starting fluid, such as ether, in the air intake system
(see air filter decal). Such fluid could cause immediate explosive
damage to the engine and possible personal injury.
Do not add gasoline, gasohol or alcohol to diesel fuel. This
practice creates a serious fire hazard and causes engine
performance problems.
1. Turn the key to ON without turning the key to START.Do not start
the engineuntil the glow-plug pre-heat indicator
turns off.
2. When the glow plug pre-heat
indicator turns off, turn the key to
START, then release the key as soon
as the engine starts. The glow plugs
will continue to be activated for two minutes after the glow plug pre-heat
indicator
has turned off. If the engine is not started before the
glow plug activation time ends, the glow plugs will need to be reset by
turning the key to OFF.
3. After the engine starts, allow it to idle for about 15 seconds. Do not
increase engine speed until the oil pressure gauge indicates normal
pressure.
STOPPING THE ENGINE
Turn the ignition to 3 (OFF).
On E-Series vehicles:To prolong engine life (after extended high
speed or maximum GVW operation), it is recommended that a hot engine
be allowed to operate at low idle for about 7–10 minutes which would
allow sufficient time for the turbocharged engine to cool down.
On F-Super Duty vehicles:To prolong engine life (especially after
extended high speed, high ambient temperature, or high GVW/GCW
operation), it is recommended that a hot engine be idled for 3-5 minutes
which will allow the turbocharged engine to cool down.
COLD WEATHER OPERATION
Changing to a lighter grade engine oil also makes starting easier under
these conditions. Refer toEngine oil specificationsin theMaintenance
and Specificationschapter of this supplement.
At temperatures below 20°F (–7°C), Number 2–D diesel fuel may thicken
enough to clog the fuel filter. Your vehicle is equipped with either an

FCM (E-Series) or an HFCM (F-Super Duty) which acts as a fuel
filter/water separator to keep the wax melted which will help prevent
fuel filter clogging. However, if the engine starts but stalls after a short
time and will not restart, the fuel filter(s) may be clogged. For best
results in cold weather, use Number 1–D diesel fuel or “winterized”
Number 2–D diesel fuel which has an additive to minimize wax
formation.
Your vehicle is also equipped with a bypass relief valve, located on the
fuel control module, which provides fuel flow to the engine if the fuel
pickup should become plugged by ice or wax. To allow the bypass valve
to function and avoid engine fuel starvation, it is recommended that,
during cold weather operation 32°F (0°C) or below, the fuel level in your
tank should not be allowed to drop below
14full. This will help prevent
air from entering the fuel system and stalling the engine.
In cold weather below 32°F (0°C), the engine will slowly increase to a
higher idle speed if left idling in P (Park). As the engine warms-up, the
engine sound level will decrease due to the activation of PCM-controlled
sound reduction features.
If your vehicle is operated in a heavy snow storm or blowing snow
conditions, the engine air induction may become partially clogged with
snow and/or ice. If this occurs, the engine may experience a significant
reduction in power output. At the earliest opportunity, clear all the snow
and/or ice away from inside the air filter assembly. Take the top off the
assembly, leaving the air filter in, and remove any snow or ice.
In order to operate the engine in temperatures of 32°F (0°C) or lower,
read the following instructions:
•Make sure that the batteries are of sufficient size and are fully
charged. Check other electrical components to make sure they are in
optimum condition.
•Use Motorcraft Premium Gold Engine Coolant solution at the
concentration recommended to protect the engine against damage
from freezing.
•Try to keep the fuel tank full as much as possible at the end of
operation to prevent condensation in the fuel system.
•Make sure you use proper cold weather engine oil and that it is at its
proper level. Also, if necessary, make sure to follow the engine oil and
filter change schedule found under theSpecial Operating Conditions
section in theScheduled Maintenance Guidechapter.
•At temperatures of -10°F (-23°C) or below, it is recommended that
you use an engine block heater to improve cold engine starting.

•The engine contains a unique “Cold Weather - Idle up feature”
calibration strategy within the PCM. Under the appropriate conditions,
the strategy will automatically elevate the engine idle speed after 130
seconds of idling in cold ambient temperatures. For this feature to be
activated, the truck must be in P (Park) (for automatic transmission),
in neutral (for manual transmission) with the parking brake applied
and engine oil temperature below 158°F (70°C). This strategy raises
the rpm to a level that reduces the potential to produce “coking” or
“wet stacking”, which is common to all diesel engines when idling for
extended periods during cold ambient temperatures.
•On F-Super Duty vehicles,a factory option for Stationary Elevated
Idle Control (SEIC) through dash-mounted Upfitter switches will allow
the operator to elevate the idle rpm for extended idle periods, as well
as aftermarket equipment such as PTO operation. This feature must
be configured even if ordered from the factory. See your authorized
dealer for required upfitting.
Operation in snow
Vehicle operation in heavy snowfall or in dry loose snow that may swirl
around the front of the vehicle may feed excessive amounts of snow into
the air intake system. This could plug the air filter with snow and cause
the engine to stall and/or lose power.
Refer toAir filter and restriction gaugein theMaintenance and
Specificationschapter of this supplement for more information.
Operation in standing water
Ingestion of water into the diesel engine can result in immediate and
severe damage to the engine. If driving through water, slow down to
avoid splashing water into the intake. If the engine stalls, and ingestion
of water into the engine is suspected, do not try to restart the engine.
Consult your dealer for service immediately.
Engine block heater (if equipped)
Refer to theDrivingchapter in theOwner’s Guide.
Rapid Heat supplemental heating system (if equipped)
The optional Rapid Heat feature is an electrically powered device that is
designed to provide supplemental heat during engine warm up. For
maximum effectiveness mid to low blower speed is recommended during
initial warm up. When operating in automatic mode (when equipped) the
climate control unit will determine the appropriate blower speed for
existing conditions.

than 5% biodiesel may be used. Use of biodiesel in concentrations
greater than 5% may cause damage to your vehicles fuel system
components such as fuel tank, fuel lines, fuel pump, fuel sender and fuel
injectors. Concentrations greater than 5% can also cause fuel filter
restrictions that may result in a lack of power and or fuel pump and fuel
injector failure.
Biodiesel fuel is a product that has been converted from renewable fuel
sources, including vegetable oil, animal fat and cooking oil. Raw or
refined vegetable oil, animal fat, cooking oil or recycled greases should
not be used.
Do not use home heating oil, agricultural fuel or any diesel fuel
not intended for highway use. Damage to the fuel injection
system, engine and exhaust catalyst can occur if an improper fuel
is used. Do not add gasoline, gasohol or alcohol to diesel fuel.
This practice creates a serious fire hazard and engine
performance problems.
FUEL REQUIREMENTS - CHOOSING THE RIGHT FUEL: VEHICLES
OPERATED WHERE ULTRA LOW SULFUR DIESEL FUEL IS NOT
REQUIRED
For a 6.4L engine to operate reliably on low sulfur or high sulfur diesel
fuel, the 6.4L engine must be a high sulfur configured engine or a ULSD
fuel-configured engine that has been retrofitted for high sulfur diesel fuel
use.
Use only a 6.4L diesel engine that has been configured for use
with high sulfur diesel fuel in markets with diesel fuel that has
sulfur content greater than 15 ppm. Using low sulfur diesel fuel
(16–500 ppm) or high sulfur diesel fuel (greater than 500 ppm) in
a 6.4L diesel engine designed to use only Ultra Low Sulfur Diesel
fuel increases the likelihood of engine oil dilution with fuel which
may lead to major engine damage. Engine damage from using the
improper type of fuel is not covered under your warranty.
Vehicles equipped with a 6.0L engine that are operated in a market that
does not require ULSD fuel may be operated on higher sulfur fuel
without any engine fuel system or emissions-related concerns.
Number 1-D or winter blend number 2-D fuel is recommended at
temperatures below 20°F (-7°C) (seeCold weather operationin the
Drivingchapter of this supplement). Diesel fuel containing no more
than 5% biodiesel may be used. Use of biodiesel in concentrations
greater than 5% may cause damage to your vehicles fuel system

On E-Series vehicles:After replacing the fuel filter, the engine will
purge the trapped air as it runs. The engine may run roughly and smoke
until the air is completely eliminated.
On F-Super Duty vehicles: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.
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.
5. Read oil level on both sides of dipstick and use highest level (reading)
for the actual engine oil level.
6. Maintain the oil level between MIN and MAX or the ADD and
OPERATING RANGE on the dipstick by adding oil as required. The
distance from MIN to MAX or ADD to OPERATING RANGE on the
dipstick represents 2.0 quarts (1.9L). Do not overfill. If the oil level
exceeds MAX or OPERATING RANGE, oil consumption may result.
Engine oil specifications
To help achieve acceptable engine performance and durability, it is
important that only engine oils of good quality are used in your diesel
engine and it is changed at the recommended interval. For normal or
severe service, use Motorcraft oil or an equivalent oil conforming to Ford
specification WSS-M2C171–E or API service categories CJ-4 or CJ-4/SM.

It is important to use these oils because they are compatible with the
emission control equipment of your vehicle to meet the more stringent
emission standards.
The use of correct oil viscosities for diesel engines is important for
satisfactory operation. Determine which oil viscosity best suits the
temperature range you expect to encounter for the next service interval
from the following SAE viscosity grade charts. The charts are separated
by vehicle/engine type due to different engine oil viscosity requirements
at different temperatures.
