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 meet the World-wide Fuel Charter should be used when
available. Ask your fuel supplier about fuel that meet the World-Wide
Fuel Charter.
Running out of fuel
Avoid running out of fuel as this will allow air to enter the fuel system,
which will make restarting the vehicle difficult.
If you have run out of fuel:
•If your vehicle is equipped with dual fuel tanks,add at least 4–5
gallons (15–19 liters) of fuel to each tank before attempting to restart
the engine.
•If your vehicle is equipped with a Caterpillar engine,the fuel
system must be primed before attempting to restart the engine. Refer
to the engine operator’s manual for instructions on priming the engine.
•Use caution not to overheat and damage the starterby cranking
the engine for an excessive period of time. You may need to crank the
engine for a longer time than normal. If the engine fails to start in 30
seconds, turn the ignition to the OFF position and wait for two
minutes before cranking the engine again.
•Any remaining trapped air will self-purge from the fuel system once
the engine starts running.
•
The engine may run rough and produce white smoke while air is in the
fuel system. This is normal and should stop after a short period of time.
Fuel filter/water separator
Do not drain water separator while engine is running. Fuel may
ignite if separator is drained while engine is running or vehicle is
moving.
The fuel filter/water separator removes any contaminated particles
and/or water from the fuel before the fuel enters the engine.
The fuel filter/water separator should be drained as recommended in the
general maintenance information section.

2. Locate the module and place an
appropriate container under the
drain plug (see illustration).
3. Remove the drain plug by turning it counterclockwise. Allow to drain
for approximately 25 seconds or until clean fuel is observed. Install the
drain plug by turning it clockwise until it is firmly seated.
4. Verify that the drain plug is closed and sealed, then remove the
container from under the vehicle.
5. Restart the engine and check WATER IN FUEL indicator light; it
should be illuminated. If it continues to illuminate, have the fuel system
checked and repaired.

2. Remove and discard the old fuel
filter element.
3. Carefully clean the mating
surfaces.
Installation-both
The engine will not run properly if the fuel filter is not installed
in housing.
1. Install new fuel filter into the fuel filter housing.
2. Tighten cap onto fuel filter housing slowly, allowing fuel to soak into
the fuel filter element. Tighten cap until it contacts the housing.
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.
Using a fuel which has more than average impurities may require
the fuel filter to be replaced more frequently than the service
interval specifies.

Refer to your engine operator’s manual for service intervals and
procedures.
FUEL CONSUMPTION IMPROVEMENT MEASURES
There are two important factors you can control to improve fuel
economy: the mechanical condition of your vehicle and how you drive it.
A properly maintained vehicle will deliver better performance than a
neglected vehicle. Always follow your maintenance schedule to keep your
vehicle in top operating condition.

SCHEDULED MAINTENANCE SERVICES
Maintenance service adjustments must conform to specifications
contained in this manual, and those shown on the Important Engine
Information Decal. The following services are to be performed at
scheduled intervals because they are considered essential to the life and
performance of your vehicle. Ford recommends that you perform
maintenance on all designated items to achieve best vehicle operation.
Scheduled maintenance beyond 100,000 miles (161,000 km) should be
continued as before 100,000 miles (161,000 km).
SPECIAL OPERATING CONDITIONS
If your driving habitsfrequentlyinclude one or more the following
conditions:
•Short trips oflessthan 10 miles (16 km) when outside temperatures
remain below freezing.
•Operating duringhot weatherin stop-and-go“rush hour”traffic.
•Operating in severe dust conditions.
•Extensive idling, or low speed operation such as door-to-door delivery
service.
•High speed operation with a fully loaded vehicle (maximum GVW).
•Snowplowing.
Perform the following:
•Change engine oil and oil filter every three months, 5,000 miles (8,000
km) or 125 hours of engine service.
•If operating in severe dust conditions, replace the air cleaner filter
more often than regular intervals as determined by the air filter
restriction indicator. Make sure that the air filter restriction indicator
is in good working order.
•Lube the manual transmission and the rear axle every 30,000 miles
(48,279 km) or six months, whichever comes first.
•See the Allison, Cummins and Caterpillar Operator’s Manual.
AIR BRAKE ADJUSTMENT
Failure to maintain proper air brake adjustment can result in
reduction or loss of braking ability.
Air brake inspection and adjustment should be performed by a qualified
service technician in accordance with the instructions in the Ford Truck
Service Manual.
