Run _ and the maintenance car maintenance _ run by and for providing. We are Zhengzhou and the Run Trading Co., Ltd. (www.stockman.com.cn) located in: Shenzhen, Guangdong specializes in: small package oil, auto parts, textiles, automotive lubricants Stockman decorations originated in the second 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 and maintenance 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 long research vehicle maintenance costs, 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, was named Stockman synthetic lubricants. Become the beginning of synthetic oil. Emission control - advantages of using the wrong lubricant may indeed reduce exhaust exhaust systems, such as the life of diesel particulate filters, etc., and may have a serious impact on maintenance costs and fuel efficiency. Our test DPF suppliers and transport operators should be implemented jointly prove this point. Stockman can slow down the speed of DPF blockage affect the actual operation of our field testing has confirmed that the car maintenance, with traditional high-ash, long replacement intervals lubricants (usually meet ACEA E4 / MB 228.5) compared Stockman (Stockman) can slow the rate of DPF blockage. This means lower exhaust backpressure (see below), then DPF maintenance means lower impact costs and / or decrease of fuel economy.
