In the increasingly stringent requirements of energy saving and environmental protection, driven by oil production technology has been improved and developed. Since the development of low viscosity multi-level energy-saving oil, not only allows the engine to save fuel 2-6%, and extended oil drain intervals to 15,000 km or more, Zhengzhou automotive lubricants, but also allows the amount of sewage into fold reduction. Therefore, the United States, gasoline engine oil, by 1972 the SE level, the development of today's SJ, SK level, to further the development in SJ / GF-2 mainly by the CC grade diesel oil development to CD, CE, GG-2 级and so on. Western Europe, Japan and other developed countries, are also developing a multi-stage low-viscosity grade of engine oil. Currently, Japan's multi-level gasoline engine oil, the market share of almost 100%, also in Europe and America more than 80%, which require a viscosity index of 95-140 base oil, and a viscosity index greater than 100 base oil, if using conventional solvent process, the paraffin-based crude oil production is very difficult, with intermediate base crude oil production is impossible. And now paraffin-based crude oil and less and less over the years, the traditional solvent-based process despite constant innovation to improve, but that the use of paraffin-based crude oil to produce a viscosity index greater than 130 base oil, lubricants Zhengzhou wholesale prices, it is very difficult . Lubricants lubricant pour point is an important indicator of quality cold flow properties. For the production, transportation and use are important. High pour point lubricating oil can not be used at low temperatures. Conversely, at higher temperatures it is not necessary to use regional low pour point oil. Lubricants lubricant pour point is an important indicator of quality cold flow properties. For the production, transportation and use are important. High pour point lubricating oil can not be used at low temperatures. On the contrary, lubricating oil wholesale market in Zhengzhou, in high temperatures areas is not necessary to use a low pour point oil. Because the lower the pour point of lubricating oil, the higher the cost of production, resulting in unnecessary waste. In general, the pour point of lubricating oil should be higher than the minimum ambient temperature is low 5 ~ 7 ℃. But particularly also mention that in the selection of the low temperature of the lubricating oil, the oil should be combined pour point, low viscosity and viscosity-temperature characteristics fully into account. Because the low pour point of the oil, its low viscosity and viscosity-temperature characteristics also may not meet the requirements. Pour point and pour point oil cold flow properties are indicators, Zhengzhou oil, both unprincipled difference, just a slightly different measurement methods. The same oil pour point and the pour point is not entirely equal, generally pour point higher than the pour point 2 ~ 3 ℃, but there are exceptions.
