Zhengzhou and the Run Trading Company (www.stockman.com.cn) is located in Shenzhen, Guangdong Province, Zhengzhou City, Garden Road, the whole way to spend a half years International Apartment, Contact: Li Klein's data show that Shell lubricants in the world occupies 13% share of the market, and continuous growth in the major growth-oriented national market share. 2008, the total lubricant demand in China is about 5.5 million tons, is the world's second largest after the United States oil market, while the share in which Shell has more than 10%. Shell Lubricants and compete globally dominant position of Exxon Mobil is also the focus of competition to the Chinese market. Data show that the current size of China's automobile market is about 100 billion yuan a year, to 2010, China's automotive aftermarket market will reach $ 23.017 billion, second only to Japan in Asia. It is reported that the dealer rebate, Shell, Mobil higher than about 1%. In addition, as a cleaning agent with Shell, Mobil will give each franchisee "Mobil 1 Car conservation" of the members of the shop offers decoration, hardware specifications, software upgrades and service management support. The viscosity of the lubricating oil in the normal operation of the engine is undoubtedly critical. In order to prevent contact between the surface of the wear of moving parts of the engine, the oil must have sufficient viscosity to be able to form a film between the moving parts of the engine in a variety of cleaning agents operating temperature, so that the smooth operation of the vehicle engine. However, the use of lubricating viscosity is too large there will be at least two levels of the state. First, the price of the catalytic cleaning agents, the viscosity is too large when the engine start is higher than the degree of the influence, it is likely to cause severe wear of the engine start-up. Since the lubricating oil viscosity is too large, slow-moving, hydraulic, although high, but by the amount of lubricating oil is not much, can not be added to the friction surface. The oil circulation rate has slowed down, the cooling and the cooling effect of the cleaning agent becomes poor, resulting in engine overheating. Due to slow oil circulation through the oil filter's frequency will become less, it is difficult to wear down in time to the late metal shavings, soot, dust cleaned out from the friction surface.
