specification WSL-M2C192-A, part number
XY-75W140-QL, 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 441).
Additional Axle Maintenance for Dual
Rear Wheels
Change rear axle fluid every
250,000 mi
(400,000 km) 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
60,000 mi
(96,000 km). In addition, follow this
60,000 mi (96,000 km) 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 3,000 mi (5,000 km).
If the available API SM or SN oils are not
available, then the oil change interval is
2,000 mi (3,000 km)
. 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
Over time, a slight amount of ash builds
up in the diesel particulate filter, which is
not removed during the regeneration
process. The filter may need to be replaced
with a new or remanufactured part at
approximately 250,000 mi (400,000 km).
Actual mileage varies depending on engine
and vehicle operating conditions.
In this case, 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.
