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 is desired. Advanced API CK-4 additive technology is fully backwards compatible with, and replaces, service categories CJ-4, CI-4 Plus, and previous.

KLONDIKE SAE 10W-30 CK-4 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.

KLONDIKE SAE 10W-30 CK-4 Synthetic Blend Heavy Duty Engine Oil meets the stringent requirements of API Service Category CK-4 for heavy duty diesel engines running on Ultra Low Sulfur Diesel (ULSD) and equipped with after treatment devices. Exceeds all requirements of current emission control systems such as Exhaust Gas Recirculation (EGR), Diesel Particulate Filter (DPF), or Selective Catalytic Reduction (SCR) technologies.

KLONDIKE SAE 10W-30 CK-4 Synthetic Blend Heavy Duty Engine Oil has gone through rigorous testing and has demonstrated it meets the thorough specifications of the engines manufactured by Detroit Diesel, Ford, Volvo, Mack, and Renault.
