The technicality, complexity and particularity of lubricant products fully reflect the necessity of lubricant technical service work and are embodied in the following aspects: Lubricating oil is a product with high technological content. Its product research and application research involves petrochemistry and machinery. Professional and other multi-disciplinary fields, cross-professional, cross-industry proficiency in lubricants professional knowledge is not easy; any mechanical design must be a reasonable lubrication design, application of any one oil is difficult to solve. However, there is a wide range of lubricants in the market, and there are many types of user industries. Users are in a state of dispersal. It is necessary to establish a large number of expert service teams with a large number of lubricants. The variety of lubricants is complex and the specifications and specifications are complex.
According to international standards, China formulates lubricant classification standards and divides lubricants into 19 categories depending on the application. Each type of oil is divided into several types. For example, E-type engine oils include gasoline engine oil, diesel engine oil, railway engine oil, and marine cylinder oil. , medium-speed tubular diesel engine oil, two-stroke gasoline engine oil, etc. There are also single-stage oils, multi-stage oils, and general-purpose oils in internal combustion engine oils. This sort of combination has nearly 100 brands. There is no certain knowledge of lubricants business, and it is difficult to select suitable lubricants; due to advances in automobile manufacturing technology. And environmental protection indicators have become increasingly stringent. Lubricants, especially internal combustion engine oils, have become the fastest-growing products in the petrochemical industry. China's oil grades differ significantly from developed countries. The level of demand for lubricants in developed countries is very small. The United States only has 2 grades of lubricants coexisting. In Europe, only 3 grades of lubricants coexist. In China, for example, gasoline engine oil has the highest grade of SL gasoline engine oil. SC even SA, SB gasoline engine oil, a difference of seven or eight grades. Due to the lack of enforcement of national oil quality grades and users’ lack of understanding of basic knowledge of upgrading existing products in place of existing oil products, it is difficult to promote new product upgrades and it is not possible to develop basic oil and oil products as in industrialized countries.
