In the highly competitive Chinese lubricants market, foreign brands have occupied a dominant position for a long time, but domestic brands have also achieved certain development in recent years. In order to stabilize the hard-won market, Sinopec took the lead in relying on lubricants subsidiaries and established the Sinopec Automotive Industry Technical Cooperation Center. Recently, Sinopec has repeatedly made efforts to cooperate with commercial vehicle manufacturers such as Shifeng Group, CNHTC Group, Dongfeng Nissan, and Foton Motor to expand the competition to the upper reaches of automobile manufacturing. The competition for lubricants has thus been upgraded. Sinopec's lubricant loading rate for vehicle manufacturers in China has reached 65%. However, it is clear that Sinopec’s ambitions do not stop there. Through the direct development of technologies for plastics and rubber and other petrochemical products with commercial vehicle manufacturing companies, the company then assigns or recommends petrochemical raw material suppliers to its component manufacturers. Or clarify the technical indicators of raw materials, it is undoubtedly extend the tentacles to the vehicle manufacturers raw material suppliers. Song Yunchang, general manager of Sinopec Lubricant Subsidiary, said that through cooperation with major auto manufacturing customers, it will enhance the application range and technological level of lubricants in automotive companies, and will also take advantage of Sinopec’s resources to support the extension of automotive industry. The development of the project led to the upgrading of Sinopec's products and the improvement of its services.
