We have a full range of multi-purpose lubricants. Lubricants form oil films on the surfaces of metal parts to lubricate and reduce friction, lower the friction coefficient, reduce component wear, and extend the service life of the engine; they fill the gap between the piston ring and the cylinder wall to form a sealing barrier, enhance the cylinder sealing, prevent gas leakage, ensure power output, and avoid oil burning and carbon deposits; they rely on cleaning dispersants to suspend metal debris, carbon deposits, sludge and other impurities generated during operation in the oil, which are filtered by the oil filter as they circulate, playing a cleaning and dispersing role; Form a protective film on the metal surface to isolate air and moisture, and neutralize the acidic substances produced by combustion, thereby preventing rust and corrosion and protecting engine equipment.
