If the engine oil is used for a long time, it will reduce the viscosity of the engine oil, cause serious water sampling, and contain a large amount of metal debris and jelly, which will seriously affect the service life and stable operation of the Rock Button Bits engine.
        1. The cooling effect reduces the heat absorption and thermal conductivity of oil much higher than that of water. If the oil deteriorates seriously, the heat dissipation function will be greatly reduced.
        2. The sealing effect is reduced, and the proper viscosity of the oil can block the gap between the cylinder block and the piston to prevent gas leakage. If the oil is not replaced for a long time, the oil will become watery and lose its sealing effect.
        3. The cleaning effect reduces the friction between metal parts, which will produce debris, and combustion will produce impurities such as carbon deposits. If the oil is not replaced for a long time, these impurities will be deposited between the parts of the engine, causing harm to the operation of the engine.
        4. The lubrication effect of Water Well Drilling Tools is reduced, and the viscosity of the oil makes it have strong adhesion, which can form a protective film between gears and shafts and other parts to make it run smoothly and reduce wear. Deteriorated engine oil basically loses this effect.
