Application of CK-4 5W-40 Engine Oil on DPF Light Trucks
With upgrading of national emission regulations for light trucks in the logistics and transportation industry,the light truck vehicles applying technologies such as diesel particulate filter(DPF)and exhaust gas recirculation(EGR)are in-creasing gradually.Application of engine post-treatment systems requires high performances of engine lubricant.In this study,the bench performance requirements of API CK-4 lubricant and the differences with Cl-4 lubricant performance were introduced,and application of CK-4 5W-40 diesel engine oil in light trucks was studied.The results show that CK-4 5W-40 on light truck vehicles installed with DPF can run 30,000 km when it uses CK-4 5W-40 diesel engine oil,which reduces vehicle operation and maintenance costs effectively in the logistics and transportation industry.
