API Diesel Engine Automotive Marine Premium Blue E
Product Description:
Premium Blue E is a high-performance high-quality heavy-duty diesel engine lubricant that meets and complies with the latest specifications and standards of the United States, Europe and Cummins.
Premium Blue E can effectively protect the valve system from abrasion and greatly reduce the piston carbon deposit and the filter blockage related to smoke caused by high temperature.
Premium Blue E is certified by Cummins and has excellent performance in various automotive, marine and industrial applications.
Premium Blue E is particularly suitable for use in modern low-emission diesel engines operating under various operating conditions. These engines include engines with a cooling exhaust gas recirculation system (EGR) designed and produced in 2002 and later.
Product advantages:
- The premium class II base oil and the unique DPT polymer differentiation technology provide excellent smoke idling control and cold start protection.
- Excellent valve protection, effectively reducing the blockage of the oil filter under high smoke idling conditions.
- Improved high temperature deposit control, and wear protection of piston rings/bearing bushes.
- The higher total base number ensures the long-term operation of the engine and effectively extends the oil drain period.
- Extensive testing of Cummins cooled exhaust gas recirculation (EGR) engines has been passed in the laboratory and on the road.
- Premiun Blue E 20W-50 is suitable for use in hot climates and can effectively solve the problem of low oil pressure caused by rising temperature.
Recommended application scenarios:
- Applicable to all heavy-duty vehicles driven by various imported diesel engines using exhaust gas recirculation (EGR).
-
At the same time, it is also suitable for various imported or domestic diesel engine-driven vehicles that are not equipped with EGR.
-
It is suitable for high-speed four-stroke diesel engines that adopt other new technologies and meet Euro IV emission regulations.
-
It can completely replace API CH-4, CG-4, CF-4, and has better performance.
