Foreign oil companies value the promotion of these two seasons very much. In the fall, they introduced multi-level plutonium and antifreeze with low pour point, low viscosity grade, and sent gifts to reflect winter features along with promotions; at the turn of spring and summer, they also promoted oils with high viscosity grades. Summer features. Lubricants are high-tech products. The average user is often ignorant of its complex technical performance and does not know how to use it for various brands. For this reason, foreign oil companies often use deep knowledge of marketing to hold technical exchange meetings, disseminate easy-to-understand oil instructions, and answer questions in return.
