CJ-4 15W-40 Diesel Engine Oil Meets the Energy-saving and Environmental Protection Requirements of BPT

In response to the energy-saving and environmental protection requirements of Beijing, Beijing Public Transport Holdings, Ltd. (BPT) requires the all-round upgrading for its diesel engine oil used by the buses, that is, replacing the CI-4 15W-40 diesel engine oil with CJ-4 15W-40 diesel engine oil. Meanwhile, BPT expects Sinopec Lubricant Company to provide CJ-4 15W-40 diesel engine oil, in order to ensure its engines and vehicle that adopt the new technologies (EGR or DPF) can meet the strict requirements on lubrication and emission and assist engines in satisfying the Europe IV/V emission requirements.

We have developed CJ-4 15W-40 products and  Passed the API certification and conducted the road test by cooperation with BPT.

Five buses of BPT (originally use CI-4 15W-40 diesel engine oil, with an oil change period of 15,000km) complete the road test of nearly 50,000km without oil change. The five buses finally complete an average test mileage of 48,525km and the longest test mileage of 50,340km. During test, five test buses operate normally and maintain the lower level of emission, showing the excellent comprehensive performance of the test oil. The buses that use CJ-4 15W-40 diesel engine oil not only extend the oil change period but also improved the fuel economy by nearly 3%, compared with the buses that use CI-4 15W-40 diesel engine oil. Data shows that CJ-4 15W-40 diesel engine oil can obviously improve the energy-saving and emission reduction of the public transportation industry.

The products meet the requirements of customers. For more than three years, BPT has always used CJ-4 15W-40 diesel engine oil.

CJ-4 15W-40 diesel engine oil can not only satisfy the increasingly strict emission regulations of the country, improve the efficiency of EGR and reduce emission but also can properly extend the service life of EGR and the oil change period, decrease the oil change times and vehicle maintenance cost and reduce the environmental pollution caused by used oil.
