Ford WSS-M2C945-B1

The Ford specification WSS‑M2C945‑B1 defines the requirements for a synthetic motor oil 5W‑20 that must have high oxidation stability, low volatility, and excellent wear protection when operating across a wide temperature range. This standard is developed for modern Ford gasoline engines with direct injection and turbocharging (EcoBoost, 1.0‑L, 1.5‑L, 2.0‑L and others), as well as for hybrid powertrains where minimal deposit formation and compatibility with catalysts and gasoline particulate filters (GPF) are important. Oil that meets WSS‑M2C945‑B1 provides stable viscosity, corrosion protection and reduced fuel consumption, meeting the requirements of an economical operating mode. For automotive service technicians this means that using XENUM products approved to this standard guarantees compliance with Ford warranty conditions and extends engine service life without risking damage to the exhaust after‑treatment system. On the xenum.ua website, in the “Type” filter select “FORD”, and you will immediately see oils that have passed testing to WSS‑M2C945‑B1, including XENUM SEMIX 5W20 and XENUM ECO PRO DX1 5W20.
