2011 FORD SUPER DUTY service interval

WARNINGS
Throughout this guide, you will find warnings identified by the
symbol
. Warnings remind you to be especially careful to reduce the
risk of personal injury.
NEW VEHICLE BREAK-IN
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,000 miles (1,600 km) of
new vehicle operation. Vary your speed to allow parts to adjust
themselves to other parts.
Drive your new vehicle at least 500 miles (800 km) before towing a
trailer. Make sure you use the specified engine oil by checking the engine
oil specification chart underEngine oilin theMaintenance and
Specificationschapter.
Do not add friction modifier compounds or special break-in oils during
the first few thousand miles (kilometers) of operation, since these
additives may prevent piston ring seating. SeeEngine oilin the
Maintenance and Specificationschapter of this supplement for more
information on oil usage.
DIESEL ENGINE INFORMATION
The diesel engine fuel system is a pressurized two-stage filtration system
and consists of:
•a frame-mounted diesel fuel conditioner module (DFCM) with an
electric fuel pump and water drain,
•an engine-mounted secondary fuel filter,
•a fuel injector for each cylinder (8 total),
•a high-pressure fuel pump,
•a high-pressure fuel rail for each cylinder bank (2 total) and
•numerous high-pressure pipes from the high-pressure pump to the
rails, and rails to the injectors.
The DFCM acts as a primary fuel filter/water separator which removes
both water and impurities from the fuel. The engine mounted filter filters
finer impurities from the diesel fuel. The engine-mounted fuel filter and
the DFCM filter should be changed at the recommended service interval
or when indicated by the message centerLOW FUEL PRESSURE
message. Refer to thescheduled maintenance informationin this
supplement for more information.

The DFCM should be drained at regular intervals or when indicated by
the message center message and water in fuel indicator light. SeeFuel
filter/water separatorin theMaintenance and Specificationschapter.
The fuel injection system is controlled through the powertrain control
module (PCM).
Fuel is drawn from the fuel tank by a frame-mounted electric fuel pump
located inside the DFCM and provides pressurized fuel to the engine.
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
service engine soon
or powertrain malfunction/reduced
power/electronic throttle control light
is illuminated, seek service
from your authorized dealer.
Lubrication system
It is important to change the engine oil at the recommended service
intervals to maintain oil viscosity. Extending the oil and filter change
interval beyond the recommended interval can negatively affect engine
performance, fuel economy and engine life. Refer toEngine oilin the
Maintenance and Specificationschapter.
Fast start glow plug system
The diesel engine glow system consists of:
•eight glow plugs (one per cylinder)
•the glow plug control module (GPCM)
•engine coolant temperature (ECT) sensor
•barometric pressure (BARO) sensor
•environmental temperature sensor

engine designed to use only Ultra Low Sulfur Diesel fuel may
result in damage to engine emission control devices and the
aftertreatment system, potentially rendering the vehicle
inoperable. Engine damage from using the improper type of fuel
is not covered under your warranty.
Vehicles with engines configured for use with high sulfur diesel fuel will
only be made available for sale in countries where ULSD fuel is generally
not available or mandated by the government. Vehicles originally sold in
a ULSD fuel market that are subsequently exported to non-ULSD fuel
markets will need to be retrofitted (at the customer’s expense) in order
to be reliably operated on non-ULSD fuel.
Diesel fuel is adjusted seasonally for cold temperature. For best results
at temperatures below 20°F (-7°C), it is recommended to use a diesel
fuel which has been seasonally adjusted for the ambient temperature.
SeeCold weather operationin theDrivingchapter of this supplement.
BIODIESEL
This vehicle may be operated on diesel fuels containing up to 20%
biodiesel, also known as B20.
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
•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.

5W-40 or 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.
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
NOTbe used.
WARNING: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 quality
It should not be necessary to add any aftermarket additives to your fuel
tank if you use a properly formulated diesel fuel that meets either the
ASTM D 975 diesel or the ASTM D7467 B6-B20 biodiesel industry
specifications. Outside of North America, use fuels meeting EN590 or
equivalent local market standard. Aftermarket additives can damage the
injector system or engine. Repairs to correct the effects of using an
aftermarket product in your fuel may not be covered by your warranty.

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. SeeMessage centerin theInstrument Clusterchapter of
yourOwner’s Guidefor message center functions. For instructions on
refilling your DEF tank, seeFilling the DEF tanklater in this section.
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 55 mph (89 km/h) and then 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.
Your vehicle’s message center will display a series of messages regarding
the amount of DEF available. A systems check will display messages
indicating the amount of DEF available (OK or under
12full) or will
produce a warning message that displays the mileage (kilometers)
remaining as the fluid in the DEF tank nears empty. For more
information on warning messages, see theMessage centersection in the
Instrument Clusterchapter of yourOwner’s Guide.

3. Reconnect both fuel lines.
Using a fuel which has more than average impurities may require
the fuel filter to be replaced more frequently than the service
interval specifies.
The system will need to be purged of air after removal/changing of the
filter. SeePurging air from the fuel system after DFCM and
engine-mounted fuel filter replacementfollowing.
Purging air from the fuel system after DFCM and engine mounted
fuel filter replacement
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.
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 is tight.
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. it is best to maintain the oil level
within the crosshatch area on the
dipstick by adding oil as required.
The lower hole is the minimum oil
level and the upper hole is the
maximum oil level. Do not overfill.
The distance from the lower hole
(oil minimum) to the upper
crosshatch area on the dipstick represents 1.0 quart (.95L).
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 Motorcraftoil or an equivalent oil conforming to
Ford specifications as listed in theMaintenance product specifications
and capacitiessection in this chapter 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 chart.
Maintenance and Specifications
41
2011 Econoline(eco)
Supplement, 1st Printing

1For severe duty usage, use SAE 5W-40 API CJ-4.
2For biodiesel (grades B5-B20) usage, use SAE 5W-40 or SAE
15W-40 API CJ-4.
An engine block heater is recommended at temperatures below –10°F
(–23°C).
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 the engine oil and oil filter
Your vehicle is equipped with an Intelligent Oil Life Monitor™ that
calculates the proper oil change service interval. When the message
center indicates:OIL CHANGE REQUIRED, change the engine oil and
oil filter. See theMessage centersection of theInstrument Cluster
chapter for more information.
Refer toMotorcraft part numberslater in this chapter for the engine oil
