Scheduled Maintenance 415
Protecting Your Investment
Maintenance is an investment that pays dividends in the form of improved
reliability, durability and resale value. To maintain the proper performance of
your vehicle and its emission control systems, it is imperative that scheduled
maintenance be completed at the designated intervals.
Vehicles with a 3.5L, 3.7L or 5.0L engine, are equipped with the
Intelligent Oil-Life Monitor (IOLM) system which shows a message in the
information display at the proper oil change service interval. This interval
may be up to one year or 10000 miles (16000 kilometers). When ENGINE
OIL CHANGE DUE or OIL CHANGE REQUIRED appears in the information
display, it's time for an oil change; the oil change must be done within two
weeks or 500 miles (800 kilometers) of the ENGINE OIL CHANGE DUE or
OIL CHANGE REQUIRED message appearing. The Intelligent Oil-Life
Monitor must be reset after each oil change. See the Information Displays
chapter.
If your information display is prematurely reset or becomes inoperative,
you should perform the oil change interval at six months or 5000 miles
(8000 kilometers) from your last oil change. Never exceed one year or
10000 miles (16000 kilometers) between oil change intervals.
Vehicles with a 6.2L engine, do not have an IOLM system. See the
7500 mile (12000 kilometers) maintenance schedule for oil change
service 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.
Ford strongly recommends using only genuine Ford, Motorcraft or
Ford-authorized remanufactured replacement parts because they are
engineered for your vehicle.
