Full Synthetic 15W-40 CK-4 Heavy Duty Motor Oil

Our Full Synthetic 15W-40 CK-4 Heavy Duty Motor Oil is engineered for the latest generation of high-output diesel engines, including those equipped with Exhaust Gas Recirculation (EGR), Diesel Particulate Filters (DPF), and Selective Catalytic Reduction (SCR) systems. Formulated with premium synthetic base oils and an advanced additive system, it provides outstanding wear protection, oxidation resistance, and deposit control under severe operating conditions.

The 15W-40 viscosity grade delivers rapid oil flow during cold starts while maintaining a strong protective film at high temperatures and under heavy loads. This ensures superior engine protection and consistent performance in both on-highway and off-highway applications.

Certified to API CK-4 standards, this oil meets or exceeds the requirements of modern diesel engines for durability, emissions compliance, and extended oil drain intervals. It effectively controls soot, minimizes viscosity increase, and helps maintain cleaner engines for optimal performance.

Key Benefits:

• Advanced wear protection for modern diesel engines

• Outstanding oxidation and thermal stability for long oil life

• Excellent soot control to reduce abrasive wear

• Compatible with EGR, DPF, and SCR emissions systems

• Ideal for severe service, high-load, and extended-drain applications

The ideal solution for fleets, construction, and industrial equipment requiring full synthetic 15W-40 CK-4 heavy-duty engine oil for superior performance and protection.
