Important role of engine oil

01Reduce friction

When the engine is running，It can reduce the friction of each part.，To prevent wear due to contact of metal parts.。

02Clean and disperse

Carbides on various parts of the engine are、Oil sludge、Worn metal particles are recycled back to the sump，Dirt generated on the working surface of each component is washed by the flow of lubricating oil。

03Cooling

Bring the heat from the running engine back to the oil tank，And then into the air.，This helps the water tank cool the engine。

04Sealing effectPrevent gas leakage from the combustion chamber，And that phenomenon of oil bur is reduced。
05Prevent corrosionPrevent corrosion of various parts of the engine due to combustion residues such as acid and water。
