2006 FORD SUPER DUTY maintenance

Engine oil specifications
To help achieve proper engine performance and durability, it is important
that only engine lubricating oils of the proper quality are used in your
diesel engine and that the engine oil is changedno laterthan the
recommended interval. Diesel engines require specially formulated oil to
resist contamination. Proper quality oils also provide maximum efficiency
of the crankcase ventilating system which reduces air pollution.
For normal or severe service, use Motorcraft oil or an equivalent oil
conforming to Ford Specification WSS-M2C171–D or API Service
categories CI-4, CI-4/SL or DHD-1. If CI-4 oil is not available, CH-4 is
acceptable.
Engine oils with improved fuel economy properties (energy conserving)
are currently available. If you use an energy conserving oil, be sure it
meets the recommended Ford Specification,APIservice categories and
SAE viscosity grades listed in the Lubricant and Maintenance Materials
Specifications chart. Some energy conserving oilsdo notmeet the
requirements necessary for your diesel engine.
* Heavy duty trailer towing with ambient temperatures above 50°F
(10°C) requires 15W-40 engine oil.
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.

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. The lower section will state energy
conserving if the oil has proven fuel saving capabilities.
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.
Use Ford Engine Oil Filter Part No. 3C3Z-6731–AA (FL–2016) or
equivalent. These filters protect your engine by filtering harmful,
abrasive or sludge particles. The FL–2016 filters 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.
Do not handle a hot oil filter with bare hands.
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:
•towing a trailer over 1,000 miles (1,600 km)

•frequent or extended idling (over 10 minutes per hour of normal
driving).
•operating in severe dust conditions.
•frequent, short trips of 10 miles (16 km) or less during freezing
weather
If you are operating your vehicle under any of these conditions, observe
the following service procedures:
•Change engine oil and filter every 5,000 miles (8,000 km).
•Use Motorcraft oil or an equivalent oil conforming to Ford
Specification WSS-M2C171–D or API categories CI-4, CI–4/SL, CI-4
PLUS or DHD-1. If CI-4 oil is not available, CH-4 is acceptable.

6. Installation is reverse of removal.
When servicing the air filter, always be sure that the auxiliary
hose is not kinked or obstructed and that it is placed back into
the hole in the front cowl near the back of the headlamp. Check
all hose and wiring positions. Failure to do so may result in
severe engine damage when driving through deep water and/or
encountering unusually heavy precipitation conditions.
EMISSION CONTROL SYSTEM(S) LAWS
Federal law prohibits vehicle manufacturers, dealers and other persons
engaged in the business of repairing, servicing, selling, leasing or trading
motor vehicles as well as fleet operations from unknowingly removing or
rendering emission control system(s) inoperative. Further, modifications
of the emission control system(s) could create liability on the part of the
individual owners under the laws of some states. In Canada,
modifications of the emission control system(s) could create liability
under applicable Federal or Provincial laws.
Do not remove or alter the original equipment floor covering or
insulation between it and the metal floor of the vehicle. The floor
covering and insulation protect occupants of the vehicle from the engine
and exhaust system heat and noise. On vehicles with no original
equipment floor covering insulation, do not carry passengers in a manner
that permits prolonged skin contact with the metal floor. Provide
adequate insulation.
NOISE EMISSIONS WARRANTY, PROHIBITED TAMPERING ACTS
AND MAINTENANCE
On January 1, 1978, Federal regulation became effective governing the
noise emission on trucks over 10,000 lbs. (4,536 kg) GVWR (Gross
Vehicle Weight Rating). The following statements concerning prohibited
tampering acts and maintenance, and the noise warranty found in the
Warranty Facts Booklet, are applicable to complete chassis cabs over
10,000 lbs. (4,536 kg) GVWR.

Tampering with noise control system prohibited
Federal law prohibits the following acts or the causing thereof: (1) The
removal or rendering inoperative by any person other than for purposes
of maintenance, repair or replacement of any device or element of design
incorporated into any new vehicle for the purpose of noise control prior
to its sale or delivery to the ultimate purchaser or while it is in use, or
(2) the use of the vehicle after such device or element of design has
been removed or rendered inoperative by any person.
Among those acts which the U.S. Environmental Protection Agency may
presume to constitute tampering are the acts listed below:
•Removal of hood blanket, fender apron absorbers, fender apron
barriers, underbody noise shields or acoustically absorptive material.
•Tampering or rendering inoperative the engine speed governor, so as
to allow engine speed to exceed manufacturer’s specifications.
The complexity of the diesel engine makes it so the owner is discouraged
from attempting to perform maintenance other than the services
described in this supplement.
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
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. 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
If the engine won’t crank
Turn on the headlights. If the lights are dim, do not go on at all or if
when the ignition is turned to 5 (START) the lights become dim or go
out, the battery connections may be loose or corroded, or the battery
may be discharged. If there is a clicking or stuttering sound coming from
the engine compartment when you turn the key to 5 (START), this may
also indicate a loose or corroded battery connection.
Check the battery connections at the battery posts, cable connection to
the engine grounding point and at the starter connection.
If a discharged battery is suspected, have it checked and corrected.
Battery posts, terminals and related accessories contain lead and
lead compounds.Wash hands after handling.
•For vehicles with manual transmissions,the clutch pedalmustbe
fully depressed in order for the starter to operate.
•For vehicles with automatic transmissions,the gearshift lever
must be in P (Park) or N (Neutral) in order for the starter to operate.
•Try operating the starter switch several times. Should the switch be
corroded, this operation may clean the contacts or make the switch
temporarily operable until you can reach the dealer.
•If all electrical connections are tight and you need assistance to start,
refer toJump startingin theRoadside Emergencieschapter of your
Owner’s Guide(F-Super Duty ) or refer to theJump starting
section in theRoadside Emergencieschapter of this supplement
(E-Series).
