SCHEDULED MAINTENANCE
The Scheduled Maintenance Services in the Service Guide are required
because they are considered essential to the life and performance of
your vehicle.
Use only recommended fuel, lubricants, fluids and service parts
conforming to Ford specifications. Motorcraft parts are designed and
built for best performance in your vehicle.
WASHING THE DIESEL ENGINE
Never wash the engine when it is warm, hot or running. Spraying water
or other cleaning fluids on a warm engine can seriously damage the
engine's fuel system. When washing the engine, the air cleaner must be
in place to prevent water from splashing into the engine.
FUEL REQUIREMENTS
The engine is designed to use low sulfur number 1±D or 2±D diesel fuel
only. At temperatures below -7ÉC (20ÉF), number 1±D or winter blend
number 2±D fuel is recommended. (See ªCold Weather Operationº in the
Startingchapter.)
Do not use fuel intended for agricultural use (agricultural fuel is
dyed red), home heating oil or any diesel fuel not intended for
highway use. Damage to the fuel injection system or engine 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.
It should not be necessary to add any aftermarket additives to your fuel
tank if you use a properly formulated diesel fuel that meets the ASTM D
975 industry specification. Aftermarket additives can damage the injector
system or engine.
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.
Do not crank the engine for more than 30 seconds at a time as
damage to the starter motor may result.
If the engine fails to start in 30 seconds, turn the key to the OFF
position and wait 30 seconds before trying again.

Engine lubrication for severe service operation
The following severe service operating conditions require unique engine
maintenance procedures:
²towing a trailer over 1 600 km (1 000 miles)
²sustained, high speed driving at Gross Vehicle Weight Rating
(maximum loaded weight for vehicle operation during hot
weather-above 32ÉC [90ÉF]).
²frequent or extended idling (over 10 minutes per hour of normal
driving).
²operating in severe dust conditions.
²frequent, short trips of 16 km (10 miles) or less during freezing
weather
If you are operating your vehicle under any of these conditions, observe
the following service procedures:
²Change engine oil and filter every 5 000 km (3 000 miles).
²Use Motorcraft oil or an equivalent oil conforming to Ford
Specification ESR-M2C171±C or API categories CG-4/SH. Do not use
oils labeled withonlyone of the following category designations, SG,
SH, CE, CF-4 or CG-4, as they could cause engine damage.
For more information refer theSevere Duty Maintenance Schedulein
the ªService Guideº.
REPLACING AIR CLEANER
When replacing the air cleaner, use a Motorcraft filter or its equivalent.
Refer toLubricant and Maintenance Materials Specificationsin this
supplement.
Failure to use the correct filter may result in severe engine
damage when driving through deep water and/or encountering
unusually heavy precipitation conditions.
1. Remove air cleaner, taking care to prevent dirt from falling into the
engine air intake.
2. Clean the air cleaner tray and cover to ensure good sealing.

VEHICLE EMISSIONS CONTROL INFORMATION (VECI)
Emissions information appears on
the VECI decal on the engine valve
cover. This decal identifies engine
displacement and provides certain
engine specifications.
SCHEDULED MAINTENANCE SERVICES
Refer to your ªService Guideº for details of maintenance on your vehicle.
If you are using your vehicle in a manner in which it will remain
stationary (door to door service, taxi, etc.), then it is recommended that
you change the engine oil every 200 engine hours as opposed to a
mileage limit. Since most vehicles are not equipped with hourmeters, it
may be necessary for you to approximate your time and plan engine oil
and filter changes accordingly.
Any modification of the emissions control system could create liability
under federal law (U.S.) if made prior to sale and registration, under the
laws of some states if made thereafter. Further, 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 knowingly removing or rendering an
emissions control system inoperative after sale and delivery to an
ultimate purchaser. In Canada, modifications of the emissions control
system could create liability under applicable federal or provincial laws.
