FORD 2013 F-150 v.3 - Manual (Page 434)

EXCEPTIONS
Normal vehicle axle maintenance: 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),
non-synthetic rear axle fluids should be changed 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 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 Technical specifications in the Capacities and
Specifications chapter for details).
Police/Taxi/Livery vehicle axle maintenance: Change rear axle fluid
every 100000 miles (160000 km). Rear axle fluid change may be waived
if the axle was filled with 75W140 synthetic gear fluid meeting Ford
specification WSL-M2C192-A, part number FITZ-19580-B or equivalent.
Add four ounces (118 mL) of additive friction modifier XL-3
(EST-M2C118-A) or equivalent for complete refill of Traction-Lok rear
axles. The axle fluid should be changed anytime the axle has been
submerged in water.
California fuel filter replacement: If the vehicle is registered in
California, the California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify the emission
warranty or limit recall liability prior to the completion of the 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 5000 miles (8000 kilometers).
If the available API SM or SN oils are not available, then the oil change
service interval is 3000 miles (4800 kilometers).
Engine air filter replacement: Engine air filter life is dependent on
exposure to dusty and dirty conditions. Vehicles operated in these conditions
require frequent inspection and replacement of the engine air filter.
