According to the function, it can be divided into: cleaning, protection, lifting, leakage prevention, repair and so on. 1. cleaning products: when added to oil, a system (such as cooling system and lubrication system) or components (such as transmission) can be cleaned without disassembly. 2. Protective articles: Adding these articles to the oil can clean, prevent corrosion and prevent the assembly and parts from rusting, and prolong the service life of the assembly and parts. 3.
