10W-30 CK-4 Synthetic Blend

KLONDIKE SAE 10W-30 CK-4 Synthetic Blend Heavy Duty Engine Oil is specifically engineered for modern diesel engines operating under severe service in a wide range of climatic conditions and ambient temperatures.

An ideal mixed fleet engine oil designed for naturally aspirated and turbocharged heavy-duty diesel engines in mobile and stationary equipment where the API CK-4 service category and SAE 10W-30 viscosity grade are specified.

KLONDIKE SAE 10W-30 CK-4 Synthetic Blend Heavy Duty Engine Oil is typically used in the same applications as SAE 15W-40 CK-4 but where greater fuel economy potential and superior cold start performance are desired. Advanced API CK-4 additive technology is fully backwards compatible with and replaces service categories CJ-4, CI-4 Plus, and previous.

This Synthetic Blend Heavy Duty Engine Oil contains field-proven additive technology delivering maximum control on engine wear, outstanding engine cleanliness, and high TBN retention for outstanding lubricant life.

This product is highly shear stable and retains OEM-mandated HTHS (high temperature, high shear) viscosity under the most extreme conditions in the engine, offering outstanding engine durability. Metal anti-wear protection exceeds API CK-4 standards and tough OEM specifications.
