Ford Motor Company API CK-4 / API FA-4 Ford Position Statement
API FA-4 Oils:
API FA-4 oils should not be used in any Ford diesel vehicles at this time due to its low viscosity.
API CK-4 Oils:
Ford also announced that it will not recommend the use of API CK-4 products in any Ford diesel
engines, new or old. Ford will now be recommending oils that meet its own OEM specification,
Ford Material Engineering Specification WSS-M2C171-F1.
Ford’s Basis for this Announcement:
Ford indicated that, based on its testing, some API CK-4 formulations showed inadequate wear protection.
Ford’s own 6.7 liter diesel engine durability testing with early prototype API CK-4 formulations revealed accelerated wear on
rocker arm fulcrums pads and push rod ends.
