What are the benefits of changing engine oil?
1 Answers
The benefits of changing engine oil are as follows: 1. Lubrication and friction reduction: There is rapid relative sliding between pistons and cylinders, as well as between main shafts and bearing bushes. To prevent excessive wear of components, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the relatively sliding component surfaces, thereby achieving the purpose of reducing wear. 2. Cooling: Engine oil can carry heat back to the oil tank and then dissipate it into the air, helping the radiator cool the engine. 3. Cleaning: Good engine oil can circulate carbon deposits, sludge, and worn metal particles from engine components back to the oil tank. Through the flow of lubricating oil, it washes away dirt generated on the working surfaces of components. 4. Sealing and leak prevention: Engine oil can form a sealing ring between piston rings and pistons, reducing gas leakage and preventing external contaminants from entering. 5. Rust and corrosion prevention: Lubricating oil can adhere to component surfaces, preventing contact with water, air, acidic substances, and harmful gases. 6. Shock absorption: When the pressure at the engine cylinder port rises sharply, suddenly increasing the load on pistons, piston rings, connecting rods, and crankshaft bearings, this load is transmitted and lubricated through the bearings, cushioning the impact load.
