Outstanding Protection for Ford* Powerstroke* Engines

Outstanding Protection for Ford* Powerstroke* Engines
Posted: November 10, 2016 - Tech Update


Ford Motor Company recently released its position on the upcoming new API CK-4 and FA-4 diesel oil specifications, claiming it will only recommend diesel oils that meet the Ford WSS-M2C171-F1 specification or oils formulated specifically for the previous API CJ-4 specification.

Questions have arisen regarding why Ford would condemn use of CK-4 and FA-4 products in its Powerstroke engines. According to Ford Service Lubricant Technical Expert Ron Romano, “6.7L engines tested on CK-4 and FA-4 formulations had experienced valve train wear not encountered with CJ-4 formulations. The CJ-4 formulations in question contained more than 1,000 parts per million phosphorus, an effective antiwear ingredient, while the CK-4 and FA-4 formulations were below that threshold. As a result, Ford declared that it has wear concerns about the use of CK-4 and FA-4 formulations with less than 1,000 ppm phosphorus in new and older Ford engines.”

All current AMSOIL synthetic diesel oils contain a boosted level of wear protection above the requirements set by the Ford specification. The new AMSOIL Signature Series Max-Duty Synthetic Diesel Oil and Heavy-Duty Synthetic Diesel Oil formulations launching in February will also contain boosted levels of wear protection, and they will carry the Ford WSS-M2C171-F1 specification. AMSOIL Dealers and customers can be well-assured that all Ford Powerstroke engines, no matter the model year, are well-protected when using AMSOIL synthetic diesel oils.
