With the development of China's auto industry and the increase in market demand caused by the growth of imported cars, China's auto engine lubricants have rapidly developed in variety and quality. However, due to the development of China's auto industry and social and economic imbalances, compared with developed countries, there are still low-end and high-grade oil co-exist, and low-grade oil still accounts for a considerable proportion of the situation. The gap between high-grade oil and the international advanced level is not large, but there is a large gap between the overall level. To improve the quality grade of automotive engine lubricants in China, it is necessary to strengthen the cooperation between automobile manufacturers and lubricant manufacturers. China's demand for automotive engine lubricants Market demand for automotive engine lubricants depends on the production conditions of the automotive industry. According to statistics, China's auto production has reached 10,000 vehicles in 9 years, and its output growth ranks ninth in the world. The output of agricultural vehicles reached 10,000, and the number of vehicles held was about 10,000. Automotive engine oil will be more demanding than industrial lubricants. It is estimated that annual total demand for engine lubricants and motor vehicles for agricultural vehicles will account for approximately 5% of total lubricants. The annual production of cars in China will reach 570,000 units, accounting for an increase in the total output of automobiles. As China’s passenger cars use gasoline engines, their Demand determines the development of gasoline engine oil in China. At present, in China’s passenger car market, grade-class vehicles are mainly made in China, and the number of grade-class vehicles is mainly imported vehicles (as the Shanghai GM Buick Guangzhou Honda Accord and FAW-VW Audi have successively put on the market and the output has continuously risen. The proportion of domestic cars will gradually increase. The grade cars mainly include Jetta Fukang Xiali Otto and other brands, which mainly use grade oils. The grade cars mainly include Santana Cherokee and Guangzhou Peugeot, using grade oil. The class-built cars made in China include Shanghai GM Buick Guangzhou Honda Accord and FAW-Volkswagen Audi and imported limousines that make or grade oil. From the perspective of market demand, mainly grade oil, grade oil growth is rapid, while the proportion of grade oil is very small. It is reported that Fukang Jetta and other manufacturers are considering the upgrading of oil and recommended service oils as grade oils. Mini cars occupy an important position in our country.
