FORD 2013 Flex v.1 - Manual (Page 386)

Additives and Chemicals
Ford Motor Company recommended additives and chemicals are listed in
this book and in the Workshop Manual. Additional chemicals or additives
not approved by Ford and are not recommended as part of normal
maintenance. Please consult your Warranty Manual for complete 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, discolored fluids that also show signs of overheating
and/or foreign material contamination should be inspected immediately by a
qualified expert such as the factory-trained technicians at your dealership.
Your vehicle’s oils and fluids should be changed 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.
