The technicality, complexity and particularity of lubricating oil products fully reflect the necessity of lubricating oil technical service work, which is embodied in the following aspects: Lubricating oil is a product with high technical content, and its product development and application research involve petrochemicals and machinery. Professional and other multi-disciplinary fields, cross-professional, cross-industry proficiency in lubricant expertise is not easy; any mechanical design must carry out a reasonable lubrication design, and any application of any kind of oil has problems. However, the lubricating oil market is wide-ranging, with many types of user industries, and users are in a state of dissociation and dispersal. It is necessary to establish a large number of expert service teams; there are many varieties of lubricating oils, and the specifications and grades are complex.
China has formulated lubricating oil classification standards with reference to international standards. Lubricants are divided into 19 categories according to application occasions. Each category 1 oil product is divided into several varieties. For example, E category internal combustion engine oil includes gasoline engine oil, diesel engine oil, railway internal combustion engine oil, and marine cylinder oil. , Medium-speed cylindrical diesel engine oil, two-stroke gasoline engine oil, etc. In the internal combustion engine oil, there are single-grade oil, multi-grade oil, and general-purpose oil. There are about a hundred brands in such a combination. Without certain lubricant business knowledge, it is difficult to choose suitable lubricants; due to the advancement of automobile manufacturing technology And environmental protection indicators are becoming more and more stringent. Lubricants, especially internal combustion engine oil, have become the fastest replacement products in the petrochemical industry. Compared with developed countries, China’s oil grade is quite different. The demand for lubricants in developed countries has a very small span. Only two grades of lubricants coexist in the United States, and only three grades of lubricants coexist in Europe. Taking gasoline engine oil as an example, China has the highest grade SL grade gasoline engine oil. There are also SC and even SA and SB grade gasoline engine oils, with a difference of seven or eight grades. Due to the country’s insufficient enforcement of oil quality grades and users do not understand the basic knowledge that upgraded products can replace original oil products, it is difficult to promote new upgraded products and cannot use oil and oil products as in industrialized developed countries.
