• 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 intervals reduce, and the
message interval adjusts accordingly.
You can drive high performance vehicles
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, oil
consumption of approximately 1 quart per
500 miles (1 liter per 800 km) is possible.
As a result, you need to check the engine
oil level at every refueling and adjust to
maintain proper levels to avoid engine
damage.
Note: Oil level should not exceed the
maximum mark on the indicator. See
Engine Oil Check (page 39).
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.
If your information display resets
prematurely or becomes inoperative, you
should perform the oil change interval. See
Normal Scheduled Maintenance (page
74).
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.

Scheduled Maintenance
72
We recommend maintenance intervals for
various parts and component systems
based upon engineering testing. We rely
on 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
recommend 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 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.
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.
