The role of engine oil

Lubrication
The main function of engine oil is to reduce the friction between the moving parts of the engine, ensure the flexible operation of the engine, and improve the operation efficiency of the machine.
Cleaning effect
The flowing lubricating oil can take away the grinding shoulder of the moving surface and the residue generated by combustion (carbon deposit), the combustion product or oxidation product of the lubricating oil (low temperature sludge) and other stains, and settle to the bottom of the oil pan, or filter the above impurities through the oil filter to protect the metal surface.
Cooling effect
The engine oil is in direct contact with the working surface, which can assist in cooling the metal parts and take away the heat generated by combustion
Antirust action
Lubricating oil can prevent rust in the metal parts of the engine, which is due to the waterproof characteristics of lubricating oil, so that the oil can effectively play the role of engine rust prevention.
Sealing action
The lubricating oil film can enter the gap between the piston ring and the cylinder, effectively improve the tightness of the engine, prevent the cylinder from gas, ensure the effective power output of the engine, and improve the vehicle power performance
Buffering
The engine oil can withstand a certain impact load from the bearing transmission, play a buffer role, so as to eliminate the impact load between the bearing and other parts of the engine to a certain extent, and prevent the damage caused by dry friction
