To help achieve acceptable engine performance and durability when
using biodiesel in your vehicle:
•Confirm the biodiesel content of the fuel to be B20 (20% biodiesel) or
less.
•Only use biodiesel fuel of good quality that complies with industry
standards.
•Follow the recommended service maintenance intervals section in the
Schedule Maintenancechapter.
•Do not store biodiesel fuel in the fuel tank for more than 1 month.
•Consider changing brands or reducing biodiesel content if you have
cold temperature fuel gelling issues or a frequentLOW FUEL
PRESSUREmessage appearing.
•Do NOT use raw oils, fats or waste cooking greases.
Use of biodiesel in concentrations greater than 20% may cause damage
to your vehicle, including engine and/or exhaust after-treatment
hardware (exhaust catalyst and particulate filter) failures. Concentrations
greater than 20% can also cause fuel filter restrictions that may result in
a lack of power and / or damage to fuel system components, including
fuel pump and fuel injector failures.
SAE 5W-40 or SAE 15W-40 oil is recommended for fuels with greater than
5% biodiesel (B5). Refer to theSpecial operating conditionssection
under theSchedule Maintenancechapter for more information about oil
change intervals and other maintenance when operating on biodiesel.
Look for a label on the fuel pump to confirm the amount of biodiesel
contained in a diesel fuel. Biodiesel content is often indicated with the
letter “B” followed by the percent of biodiesel in the fuel. For example,
B20 indicates a fuel containing 20% biodiesel. Ask the service station
attendant to confirm the biodiesel content of a diesel fuel if you do not
see a label on the fuel pump.
Biodiesel fuels degrade more easily than diesel fuels not containing
biodiesel and should not be stored in the fuel tank for more than 1 month.
If your vehicle will be parked or stored for more than 1 month, then your
vehicle fuel tank should be emptied of biodiesel fuel, filled with a pure
petroleum-based diesel fuel, and run for a minimum of 30 minutes.
Note:Degraded or oxidized biodiesel can damage fuel system seals and
plastics and corrode steel parts.
During cold weather, if you have problems operating on biodiesel, you
may need to use a diesel fuel with lower biodiesel content, try another
brand, or discontinue the use of biodiesel.

DIESEL FUEL ADDITIVES
It should not be necessary to add any aftermarket additives to your fuel
tank if you use a properly formulated diesel fuel. Aftermarket additives
can damage the injector system or engine.
Use Motorcraft® cetane booster or an equivalent cetane booster additive
if you suspect fuel has low cetane. Use Motorcraft® anti-gel &
performance improver or an equivalent additive if there is fuel gelling.
Do not use alcohol based additives to improve cetane quality, to prevent
fuel gelling or any other use. The use of alcohol additives may result in
damage to the fuel injectors/system. refer to theTechnical
specificationssection in theCapacities and Specificationschapter for
more information.
Repairs to correct the effects of using an aftermarket product that does
not meet Ford specifications in your fuel may not be covered by your
warranty.
Note:Ultra Low Sulfur Diesel fuel is designed to meet the emissions
standards for the 6.7L engine and is backward compatible as well (i.e.,
can be used in Ford 7.3L, 6.9L, 6.4L and 6.0L diesel engines in Ford
vehicles).
FUELING TIPS
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.
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. To
purge the air sooner: prior to engine start, prime the system by turning
the key to on for 30 seconds then to off. Repeat this several times. 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.

Care should be taken whenever diesel fuel is stored. Use only clean,
approved containers which will prevent the entry of dirt or water.
Diesel fuel must not be stored in a galvanized container. The fuel will
dissolve the zinc in a galvanized container. The zinc will then remain in
the solution until it is run through the engine where it will be deposited
in the fuel injectors causing expensive-to-repair damage.
Diesel fuel dispensing nozzle fill rate
This truck is equipped with a fuel fill pipe which is able to accept fuel up
to 20 gallons per minute from a 1
1 8fuel dispensing nozzle. Pumping fuel
at greater flow rates may result in premature nozzle shut-off or spitback.
Fuel filler cap
WARNING:The fuel system may be under pressure. If the fuel
filler cap is venting vapor or if you hear a hissing sound, wait
until it stops before completely removing the fuel filler cap. Otherwise,
fuel may spray out and injure you or others.
WARNING:If you do not use the proper fuel filler cap,
excessive pressure or vacuum in the fuel tank may damage the
fuel system or cause the fuel cap to disengage in a collision, which may
result in possible personal injury.
Note:If you must replace the fuel filler cap, replace it with a fuel filler
cap that is designed for your vehicle. The vehicle warranty may be void
for any damage to the fuel tank or fuel system if the correct genuine
Ford or Motorcraft® fuel filler cap is not used.
Your fuel tank filler cap has an indexed design with a 1/4 turn on/off feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise until it spins off.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with the notches on the
filler pipe.
5. Turn the filler cap clockwise 1/4 of a turn until it clicks at least once.

SELECTIVE CATALYTIC REDUCTION (SCR) SYSTEM
Your vehicle is equipped with a selective catalytic reduction (SCR)
system to help reduce emission levels of oxides of nitrogen from the
exhaust of the diesel engine. The system automatically injects diesel
exhaust fluid (DEF) into the exhaust system to enable proper SCR
function.
Importance of maintaining the DEF level
In order for the SCR system to operate properly, the DEF level must be
maintained. Generally, the DEF tank should be filled during the oil
change service interval. See thescheduled maintenance informationin
this supplement for more information. However, certain conditions or
driving styles, such as trailer towing or fast rates of acceleration, will
require the refilling of the DEF tank more often.
The engine control unit will monitor the amount of fluid available in the
DEF tank. Running a system check in the message center will indicate
whether the DEF level is ok or if it is less than 1/2 full. A message will
automatically be displayed in the message center when the DEF level is
low and needs to be refilled. When you see this message you should refill
your tank. See theInformation displayschapter of yourOwner’s
Manualfor information display functions. For instructions on refilling
your DEF tank, seeFilling the DEF tankin theFuel and Refueling
chapter.
DEF warning messages and vehicle operations
WARNING:Diesel Exhaust Fluid (DEF) must be refilled when
low or replaced when contaminated or the vehicle speed will be
speed limited to 50 mph (80 km/h). In these conditions, drive with
caution and refill DEF immediately. If the DEF becomes empty or
contaminated fluid is not replaced, the vehicle will become limited to
idle speed only once stopped. In these conditions, be cautious where
you stop the vehicle because you may not be able to drive long
distances and will not be able to maintain highway speeds until DEF is
refilled or replaced.
WARNING:Tampering or disabling your vehicle’s exhaust
aftertreatment system will result in severe vehicle performance
limitation including eventual speed limiting to 5 mph.
