Full Synthetic 10W-40 CK-4 Heavy Duty Motor Oil

Our Full Synthetic 10W-40 CK-4 Heavy Duty Motor Oil is designed for demanding diesel engine applications that require superior protection and performance in extreme operating conditions. This premium formulation uses top-tier synthetic base oils and a cutting-edge additive system to provide unmatched wear protection, thermal stability, and deposit control.

The 10W-40 viscosity grade ensures reliable cold-weather performance while maintaining a robust oil film at elevated temperatures and heavy loads. It is an excellent choice for mixed fleets, off-road equipment, and industrial applications where high temperature protection and extended service intervals are critical.

Certified to API CK-4 standards, this oil is fully compatible with advanced emissions control technologies, including Diesel Particulate Filters (DPF), Exhaust Gas Recirculation (EGR), and Selective Catalytic Reduction (SCR). It offers excellent soot management, oxidation resistance, and shear stability for long-lasting engine protection and improved efficiency.

Key Benefits:

• Exceptional high-temperature protection and thermal stability

• Superior wear control for extended engine life

• Excellent soot dispersion to maintain engine cleanliness

• Advanced oxidation resistance for longer oil drain intervals

• Compatible with modern emissions systems (DPF, EGR, SCR)

Ideal for severe-duty diesel engines in trucks, construction, and industrial machinery requiring the premium protection of a full synthetic 10W-40 CK-4 oil.
