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 10°C
(50°F) 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 the scheduled maintenance guide.
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 section
Engine 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 1,600 km (1,000 miles)
•sustained, high speed driving at Gross Vehicle Weight Rating
(maximum loaded weight for vehicle operation during hot
weather-above 32°C [90°F]).
•frequent or extended idling (over 10 minutes per hour of normal
driving).
•operating in severe dust conditions.
•frequent, short trips of 16 km (10 miles) or less during freezing
weather
Maintenance and specifications

•Overloading or pulling heavy trailers during hot weather.
•Grill or radiator air blockage.
•Slipping or missing drive belt.
•Plugged or very dirty air cleaner element.
If fuses burn out
Burned-out or blown fuses usually indicate an electrical short-circuit,
although a fuse may occasionally burn out from vibration. Insert a second
fuse. If this fuse immediately burns out and you cannot locate the cause,
return your vehicle to your dealer for a circuit check.
Replacement fuses and circuit breakers must always be the same
rating as the original equipment shown. Never replace a fuse or
circuit breaker with one of a higher rating. Higher rated fuses or circuit
breakers could allow circuit overloading in the event of a circuit
malfunction, resulting in severe vehicle damage or personal injury due
to fire.
Refer to the“Owner Guide”for replacement of fuses.

GENERAL MAINTENANCE INFORMATION
Why maintain your vehicle?
This guide describes the scheduled maintenance required for your
vehicle. Carefully following this schedule helps protect against major
repair expenses resulting from neglect or inadequate maintenance and
may also help to increase the value of your vehicle when you sell or
trade it.
It is your responsibility to see that all scheduled maintenance is
performed and that the materials used meet Ford engineering
specifications. Failure to perform scheduled maintenance specific in this
guide will invalidate warranty coverage on parts affected by the lack of
maintenance. Be sure receipts for completed maintenance are kept with
the vehicle and confirmation of the work performed is always recorded in
this guide.
Your Ford or Lincoln Mercury dealer, or Ford or Lincoln Mercury Quality
Care Center has factory trained technicians who can perform the
required maintenance using genuine Ford parts. They are committed to
meeting your service needs and to assuring your continuing satisfaction.
Protecting your investment
Maintenance is an investment that will pay dividends in the form of
improved reliability, durability and resale value. To assure the proper

life. These lubricants are not to be checked or changed unless a leak is
suspected, service is required or the axle assembly has been submerged
in water. The axle and PTO lubricant should be changed anytime the
axle and PTO have been submerged in water. Non-synthetic rear axle
lubricants should be replaced every 3,000 miles or 3 months, whichever
occurs first, during extended trailer tow operation above 21 Celsius (70
degrees Fahrenheit) ambient and wide open throttle for extended
periods above 45 mph. The 3,000 mile lube change interval may be
waived if the axle was filled with 75W140 synthetic gear lubricant
meeting Ford specification WSL-M2C192-A, part number F1TZ-19580-B
or equivalent. Add four ounces of additive friction modifier
C8AZ-19B546-A (EST-M2C118-A) or equivalent for complete refill of
Traction-Lok rear axles. The axle lubricant should be changed anytime
an axle has been submerged in water.
F-450 and F-550 axle maintenance
Replace rear axle lubricant every 100,000 miles under normal driving
conditions on all F-450 and F-550 commercial applications. For F-450
and F-550 trucks operated at or near maximum Gross Vehicle Weights,
the rear axle lubricant should be replaced every 50,000 miles. In
addition, this 50,000 mile schedule should be observed when the vehicles
are operated under the Special Operating Conditions.
