•
Under normal operating conditions, a
message appears in the information
display to indicate the regular oil
change interval.
• Under severe operating conditions, the
oil change interval may reduce, and the
message interval may adjust.
High performance vehicles can be driven
in such a way that may lead to higher oil
consumption (this includes extended time
at high engine speeds, high loads, engine
braking, hard cornering maneuvers, and
track use). Under these conditions, the
engine oil level needs to be checked at
every refueling and adjusted to maintain
proper level to avoid engine damage.
Note: Oil level should not exceed the
maximum mark on the indicator. See
Engine Oil Check (page 237).
When the oil change message appears in
the information display, it is time for an oil
change. Make sure you perform the oil
change within two weeks or
500 mi
(800 km) of the message appearing. Make
sure you reset the Intelligent Oil-Life
Monitor after each oil change. See
Oil
Change Indicator Reset (page 238).
If your information display resets
prematurely or becomes inoperative, you
should perform the oil change interval at
six months or
5,000 mi (8,000 km) from
your last oil change. Never exceed one year
or
10,000 mi (16,000 km) between oil
change intervals.
Your vehicle is very sophisticated and built
with multiple, complex, performance
systems. Every manufacturer develops
these systems using different
specifications and performance features.
That is why it is important to rely upon your
dealership to properly diagnose and repair
your vehicle. Ford Motor Company has recommended
maintenance intervals for various parts
and component systems based upon
engineering testing. Ford Motor Company
relies upon this testing to determine the
most appropriate mileage for replacement
of oils and fluids to protect your vehicle at
the lowest overall cost to you and
recommends against maintenance
schedules that deviate from the scheduled
maintenance information.
We strongly recommend the use of only
genuine Ford, Motorcraft or
Ford-authorized re-manufactured
replacement parts engineered for your
vehicle.
Additives and Chemicals
This owner's manual and the Ford
Workshop Manual list the recommended
additives and chemicals for your vehicle.
We do not recommend using chemicals or
additives not approved by us as part of
your vehicle
’s normal maintenance. Please
consult your warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a
normal operating characteristic and, by
itself, does not necessarily indicate a
concern or that the fluid needs to be
changed. However, a qualified expert, such
as the factory-trained technicians at your
dealership, should inspect discolored fluids
that also show signs of overheating or
foreign material contamination
immediately.
401
Mustang (CZG) Canada/United States of America, Vehicles Built From: 15-07-2019, enUSA, Edition date: 201906, Second-Printing Scheduled Maintenance

Make sure to change your vehicle
’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a
viable way to change fluid for many vehicle
sub-systems during scheduled
maintenance. It is critical that systems are
flushed only with new fluid that is the same
as that required to fill and operate the system or using a Ford-approved flushing
chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals.Check every month
Engine oil level.
For severe use, high engine speed and engine loads, engine braking and track use, check engine oil level every fuel fill-up.
Function of all interior and exterior lights.

Multi-Point Inspection
In order to keep your vehicle running right,
it is important to have the systems on your
vehicle checked regularly. This can help
identify potential issues and prevent major
problems. We recommend having the

at every scheduled maintenance interval
to help make sure your vehicle keeps
running great.Multi-Point inspection

Be sure to ask your dealership service
advisor or technician about the multi-point
vehicle inspection. It is a comprehensive
way to perform a thorough inspection of
your vehicle. Your checklist gives you
immediate feedback on the overall
condition of your vehicle. NORMAL SCHEDULED
MAINTENANCE
Intelligent Oil-Life Monitor™
Your vehicle has an Intelligent Oil-Life
Monitor that determines when you should
change the engine oil based on how you
use your vehicle. By using several
important factors in its calculations, the
monitor helps reduce the cost of owning
your vehicle and reduces environmental
waste at the same time.

Mustang (CZG) Canada/United States of America, Vehicles Built From: 15-07-2019, enUSA, Edition date: 201906, Second-Printing Scheduled Maintenance

Exceptions
There are several exceptions to the Normal
Schedule:
Rear Axle Maintenance
Axle fluid changes or level checks are not
required unless a leak is suspected or the
assembly has been submerged in water.
Have the axle checked as soon as possible.
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 (4,800 km).
If the available API SM or SN oils are not
available, then the oil change interval is
1,800 mi (2,900 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.
