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, make sure
you have scheduled maintenance performed at the designated 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.
