Full Synthetic 10W-30 CK-4 Heavy Duty Motor Oil

Our Full Synthetic 10W-30 CK-4 Heavy Duty Motor Oil is designed to meet the demanding needs of modern diesel engines operating under severe service conditions. Formulated with premium synthetic base stocks and an advanced additive system, this oil offers maximum protection against wear, deposits, and oil breakdown, ensuring long engine life and reduced maintenance costs.

The 10W-30 viscosity grade provides exceptional low-temperature performance for easier starts while maintaining a durable oil film under high operating temperatures and heavy loads. Compared to traditional 15W-40 oils, this grade improves fuel economy while still delivering heavy-duty protection.

Certified to API CK-4 specifications, this oil is fully compatible with engines equipped with Diesel Particulate Filters (DPF), Exhaust Gas Recirculation (EGR), and Selective Catalytic Reduction (SCR) systems. Its advanced formula ensures excellent soot handling and oxidation stability, enabling longer drain intervals and cleaner engine performance.

Key Benefits:

• Superior wear protection for high-output diesel engines

• Improved fuel efficiency compared to higher-viscosity oils

• Excellent cold-start performance and all-weather reliability

• Advanced oxidation and thermal stability for extended oil life

• Fully compatible with modern emissions control systems

Ideal for fleets, construction equipment, and industrial machinery requiring a full synthetic 10W-30 CK-4 oil for maximum performance and durability under tough conditions.
