Ford Mustang (2018 year). Manual - part 108

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

NORMAL SCHEDULED
MAINTENANCE

Intelligent Oil-Life Monitor™

Your vehicle is equipped with an Intelligent
Oil-Life Monitor that determines when you
should change the engine oil based on how
your vehicle is used. 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.

This means you do not have to remember
to change the oil on a mileage-based
schedule. Your vehicle lets you know when
an oil 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 message prompting you to change your oil
