Synthetic Blend 15W-40 CJ-4 Heavy Duty Motor Oil

Our Synthetic Blend 15W-40 CJ-4 Heavy Duty Motor Oil is designed for the latest generation of diesel engines, including those equipped with Exhaust Gas Recirculation (EGR), Diesel Particulate Filters (DPF), and Selective Catalytic Reduction (SCR) systems. By blending high-quality base oils with advanced synthetic components, this oil delivers superior thermal stability, extended oil life, and improved protection over conventional oils.

The 15W-40 multi-grade viscosity provides excellent low-temperature performance for easier cold starts while maintaining strong oil film protection under high-temperature and heavy-load conditions. This makes it ideal for severe-duty on-highway and off-highway applications.

Certified to API CJ-4 standards, this oil is specifically formulated to reduce ash, phosphorus, and sulfur levels to protect advanced emission control systems. It offers exceptional soot dispersion, helping prevent viscosity increase and abrasive wear, while maintaining engine cleanliness and durability.

Key Benefits:

• Advanced wear protection for extended engine life

• Outstanding thermal stability and oxidation resistance

• Excellent soot and deposit control to keep engines clean

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

• Ideal for severe service and extended drain intervals

A great choice for fleets, construction, and industrial equipment that demand the performance of a synthetic blend oil in a 15W-40 CJ-4 formulation.
