change is due by displaying a message in
the information display.
The following table provides examples of
vehicle use and its impact on oil change
intervals. It is a guideline only. Actual oil
change intervals depend on several factors
and generally decrease with severity of
use.When to Expect the OIL CHANGE REQUIRED Message

Axle(s) and transfer case, four-wheel drive
vehicles, fluid changes or level checks are
not required unless a leak is suspected, or
the assembly has been submerged in
water. Contact an authorized dealer for
service. 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
For vehicles operating in the Middle East,
North Africa, Sub-Saharan Africa or
locations with similar climates using an oil
that meets our specification or has an
American Petroleum Institute (API)
Certified for Gasoline Engines (Certification
mark) oil, the normal oil change interval is
3,000 mi (4,800 km)
.

F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Scheduled Maintenance

Engine Air Filter Replacement
The life of the engine 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.
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, a 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, the engine control system sets a
service light, a wrench or engine icon, to
inform you to bring your vehicle to the
dealer for service.
