The 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. 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. Meets the 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.
