Stockman lubricants originated during World War II. Before World War II engine structure is simple, using a simple method by physical refining to meet most of the normal operation of the engine under the prevailing conditions, but can not meet during the war frequently wear military machinery and equipment. So, by George Carteret Marshall proposed by the district in fifty-one created a specially established for military activities Research Group. Responsible for the improvement and development of military equipment, and maintenance, including a man named Stockman's research staff responsible for the development of new anti-wear lubricants to extend the operational life of machinery. Under the leadership of Stockman after a long period of research, on the basis of previous lubricant additives such as increased wear, compared with the product of oil mineral oil, extreme pressure resistance, oxidation resistance stronger lubrication Oil knowledge, was named Stockman synthetic lubricants. Become the beginning of synthetic oil. Modern high output, low emissions diesel soot produced higher operating temperature than the older style naturally aspirated engine is higher, thus the high performance requirements of the engine oil significantly increased. Popular compact design reduces the oil consumption of the engine, and thus supplement the lack of new oil additive consumed. Furthermore, the higher the position of the top piston ring lubricating oil film closer to the high-temperature combustion chamber, lubricating oil is subjected to a corresponding increase in thermal stress. Improved fuel injection pressure and injection cycle delay can effectively control emissions, but also improve the operating temperature and the amount of soot exhaust gas recirculation engines. Stockman Black Edition 15W-40 at high temperatures can still provide excellent lubricating effect. This product is also fully compatible with conventional oils. The main advantages are as follows: ■ Help lasting engine life and extended oil change intervals ■ Enhanced antioxidant capacity oil company, the control piston coke and extend oil life ■ excellent soot dispersion capacity, protect the engine wear and carbon ■ excellent control engine cleanliness helps save fuel ■ ■ meet ■ Global DHD-1 specification excellent low temperature properties, cold start is more convenient to control engine wear and damage ■ suitable for mixed fleet of gasoline and diesel, specifically designed for long-lasting engine life and the Run, lubricating oil, lubricating oil and the run by.
