What is the function of engine oil maintenance?
2 Answers
The functions of engine oil maintenance are: 1. Lubrication, enabling smooth sliding between pistons and cylinders, and between main shafts and bearing bushes to prevent part wear; 2. Assisting in cooling and temperature reduction; 3. Cleaning carbon deposits and sludge from engine parts; 4. Sealing to prevent leakage, avoiding gas leakage and the entry of external pollutants; 5. Rust and corrosion prevention; 6. Shock absorption and cushioning; 7. Anti-wear. The steps for changing engine oil are: 1. Lift the car, remove the protective plate, and place a container with a capacity of about 10 liters under the oil drain plug; 2. Unscrew the oil drain plug, use an air gun to blow for two minutes at the oil filler port, tighten the oil drain plug after draining, and wipe with a tissue to check for oil leakage; 3. Reinstall the protective plate, lower the car, and use a funnel to align with the oil filler port to add engine oil.
Having driven for fifteen years, my deepest realization is how crucial engine oil maintenance is. Those metal components in the engine spin thousands of times per minute, relying entirely on the oil for lubrication and cooling. Old oil becomes viscous and accumulates sludge, essentially making parts grind against each other like sandpaper. Once, I forgot to change the oil, and the engine started rattling like a tractor—when I opened it up, the bearings had worn grooves. Fresh oil carries away metal shavings and carbon deposits while forming a sealing layer around the pistons to reduce blow-by. Now, I strictly follow the odometer for maintenance. Spending a few hundred on an oil change beats shelling out tens of thousands for engine repairs. Oh, and during cold winter starts, quality oil spares the engine unnecessary strain—something seasoned drivers value most.
