A: Hello, thank you for your question. Here is the information that we received from the vendor: Yes, Ultra1Plus SAE 0W-20 Synthetic Motor Oil formulated to meet API SP and ILSAC GF-6A standards is compatible with and meets the technical performance requirements of Ford specification WSS-M2C962-A1. Explanation: Ford WSS-M2C962-A1 is an OEM specification that aligns with the ILSAC GF-6A standard and API SP category. This specification applies to gasoline engines requiring 0W-20 viscosity and is designed to ensure performance in areas such as: Low-speed pre-ignition (LSPI) protection Timing chain wear protection Improved fuel economy Enhanced sludge and varnish control Excellent piston cleanliness Oxidation stability The ILSAC GF-6A standard was developed jointly by OEMs including Ford, and its requirements form the foundation of the WSS-M2C962-A1 specification. Therefore, a motor oil meeting API SP and ILSAC GF-6A is functionally compliant with Ford’s WSS-M2C962-A1 specification, provided it passes the required bench and engine tests outlined in SAE J183 and ASTM protocols. Note: While Ford does not operate a public licensing program like API, the WSS-M2C962-A1 specification does not require additional proprietary testing beyond API SP / GF-6A for aftermarket oils, unless otherwise stated for factory fill or special OEM approvals.
