Part Description: 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.
