Ford F150-F250-F350-F450-F550 2012 Maintenance & User Manual
Ford strongly recommends the use of genuine Ford replacement parts. Parts other than Ford, Motorcraft or Ford-authorized remanufactured parts that are used for maintenance replacement or for the service of components affecting emission control must be equivalent to genuine Ford Motor Company parts in performance and durability.
It is the owner’s responsibility to determine the equivalency of such parts. Please consult your Warranty Guide for complete warranty information. Chemicals or additives not approved by Ford are not required for factory recommended maintenance. In fact, Ford Motor Company recommends against the use of such additive products unless specifically recommended by Ford for a particular application.
