Full Synthetic 5W-40 CK-4 Heavy Duty Motor Oil

Our Full Synthetic 5W-40 CK-4 Heavy Duty Motor Oil is engineered for high-performance diesel engines operating under the most demanding conditions. Using premium synthetic base oils and a cutting-edge additive system, it provides unmatched protection against wear, deposits, and oil breakdown, ensuring long-lasting performance and durability.

The 5W-40 viscosity grade delivers outstanding low-temperature fluidity for quick starts in extreme cold while maintaining robust oil film strength under heavy loads and high temperatures. This makes it the preferred choice for fleets, off-road equipment, and industrial machinery requiring reliable performance in all climates.

Certified to API CK-4 specifications, this oil is fully compatible with advanced emissions control systems, including Diesel Particulate Filters (DPF), Exhaust Gas Recirculation (EGR), and Selective Catalytic Reduction (SCR). Its superior oxidation resistance, soot control, and thermal stability allow for extended drain intervals, reducing downtime and maintenance costs.

Key Benefits:

• Maximum wear protection under extreme operating conditions

• Outstanding cold-weather performance for fast starts

• Exceptional oxidation stability for extended oil life

• Excellent soot handling and deposit control

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

Ideal for severe-service diesel engines in trucks, construction, and industrial applications that demand the premium performance of a full synthetic 5W-40 CK-4 oil.
