Notes:
In 2016, with the introduction of the American Petroleum Institute (API) CK-4 standard, Ford superseded its original recommendation of WSS-M2C171-C with the new WSS-M2C171-F1 specification. Ford's official stance is to continue recommending motor oils meeting Ford's WSS-M2C171-F1 specification over standard CK-4 oils for its 3.2L, 6.7L, and older diesel engines (4.5L, 6.0L, 6.4L, and 7.3L). This is because testing on some CK-4 oils revealed inadequate wear protection compared to previous CJ-4 formulas. To address this, Ford's WSS-M2C171-F1 standard includes extra requirements for added wear protection. Similar to other diesel engine manufacturers, Ford advises using oils that meet its specific internal Original Equipment Manufacturer (OEM) standard, which is the Ford Material Engineering Specification WSS-M2C171-F1.
