The reasons for high oil consumption include: 1. Oil leakage; 2. Clogged crankcase ventilation pipes; 3. Wear of valve stems and valve guides; 4. Wear or damage of valve stem oil seals; 5. Incorrect installation of piston rings during maintenance, causing oil to enter the combustion chamber; 6. Piston rings stuck in the ring grooves due to gumming or severe wear; 7. Improper selection of lubricating oil with too low viscosity; 8. Excessive addition of lubricating oil. The functions of engine oil are: lubrication, auxiliary cooling, cleaning, sealing and leak prevention, rust and corrosion prevention, shock absorption, and anti-wear. Engine oils are categorized into mineral oil, semi-synthetic oil, and full synthetic oil.
