Exceptions
There are several exceptions to the Normal
Schedule:
Axle Maintenance
Change the axle fluid anytime an axle is
submerged in water. Rear axles and power take-off units with
synthetic fluid and light-duty trucks
equipped with Ford-design axles are
lubricated for life; do not check or change
fluid unless a leak is suspected, service is
required or the assembly has been
submerged in water. During long periods
of trailer towing with outside temperatures
above 70°F (21°C) and at wide-open
throttle for long periods above 45 mph (72
km/h), change non-synthetic rear axle fluid
every 3000 miles (4800 kilometers) or
three months, whichever comes first. This
interval can be waived if the axle is filled
with 75W140 synthetic gear fluid meeting
464
Super Duty (), enUSA Scheduled Maintenance

Ford specification WSL-M2C192-A, part
number F1TZ-19580-B, or equivalent. Add
friction modifier XL-3 (EST-M2C118-A) or
equivalent for complete refill of
Traction-Lok rear axles. See Capacities
and Specifications (page 301).
Additional Axle Maintenance for F-450
and F-550
Change rear axle fluid every 100000 miles
(160000 kilometers) under normal driving
conditions on all commercial applications.
When operating your vehicle at or near
maximum gross vehicle weights, change
the rear axle fluid every 50000 miles
(80000 kilometers). In addition, follow
this 50000-mile (80000-kilometer)
schedule when operating your vehicle
under the special operating conditions,
where noted.
California Fuel Filter Replacement
If you register your vehicle in California, the
California Air Resources Board has
determined that the failure to perform this
maintenance item does not nullify the
emission warranty or limit recall liability
before the completion of your vehicle's
useful life. Ford Motor Company, however,
urges you to have all recommended
maintenance services performed at the
specified intervals and to record all vehicle
service.
Hot Climate Oil Change Intervals
Vehicles operating in the Middle East,
North Africa, Sub-Saharan Africa or
locations with similar climates using an
American Petroleum Institute (API)
Certified for Gasoline Engines (Certification
mark) oil of SM or SN quality, the normal
oil change interval is 3000 miles (5000
kilometers). If the available API SM or SN oils are not
available, then the oil change interval is
1800 miles (3000 kilometers).
Engine Air Filter and Cabin Air Filter
Replacement
The life of the engine air filter and cabin air
filter is dependent on exposure to dusty
and dirty conditions. Vehicles operated in
these conditions require frequent
inspection and replacement of the engine
air filter and cabin air filter.
Diesel Particulate Filter
The filter may need to be removed for ash
cleaning at approximately 120000 miles
(192000 kilometers) or greater (actual
mileage can vary greatly depending upon
engine and vehicle operating conditions)
and replaced with a new or
re-manufactured (ash cleaned) part. The
filter may need to be replaced at
approximately 250000 miles (400000
kilometers) depending upon engine and
vehicle operating conditions. In both cases,
the engine control system sets a service
light (wrench icon) to inform you to bring
your vehicle to the dealer for service. If
there are any issues with the oxidation
catalyst or particulate filter system, a
service light (wrench or engine icon) sets
by the engine control system to inform you
to bring your vehicle into a dealer for
service.
