WSS-M2C214-B1 Diesel Motor Oil

What is WSS-M2C214-B1?

WSS-M2C214-B1 is a Ford Motor Company specification designed for diesel motor oil that meets API FA-4 standards. This low viscosity oil improves fuel economy, engine protection, and the performance of modern diesel engines.

Using the correct oil is critical for Ford diesel vehicles, commercial vehicles, and heavy-duty diesel engines to prevent excessive wear, increased emissions, and system failures.

Why WSS-M2C214-B1 is the Best Choice of Oil for Diesel Engines

1. Low Viscosity Oil for Fuel Efficiency

This SAE 5W-30 diesel motor oil is formulated for fuel savings while maintaining high engine performance. Lower internal friction leads to:

✔ Better fuel economy for Ford F-150, Super Duty, and commercial vehicles

✔ Enhanced performance in Cummins CES, MACK EOS-5, JOHN DEERE, and Euro VI engines

✔ Reduced oil consumption, lowering maintenance costs over time

2. Excellent Protection Against Wear & Deposits

Engines operate under extreme conditions, generating soot, deposits, and high temperatures. This oil provides excellent protection by meeting ASTM D2896 and ASTM D874 standards for:

✔ Wear protection for cylinder heads, fuel filters, and timing belts

✔ Resistance to high-temperature oxidation, preventing sludge formation

✔ Extended oil drain intervals, reducing downtime and labor costs

3. Compatibility with Exhaust Aftertreatment Systems

Modern diesel engines rely on exhaust gas aftertreatment systems like Diesel Particulate Filters (DPF) and Selective Catalytic Reduction (SCR) to meet emissions regulations.

This WSS-M2C214-B1 diesel oil ensures:

✔ Extended lifespan of aftertreatment systems

✔ Soot control for cleaner engine operation

✔ Compliance with API FA-4 and API FA emissions standards

4. Cold-Weather Performance & Viscosity Stability

Cold starts are a major concern for diesel engines, especially in winter conditions. WSS-M2C214-B1 diesel motor oil provides:

✔ Smooth cold starts in temperatures as low as -20°F (-29°C)

✔ Stable viscosity grade, preventing oil thickening

✔ Reduced oil consumption in extreme cold
