What are the reasons for excessive engine oil consumption in cars?
1 Answers
Excessive engine oil consumption in cars can be attributed to the following reasons: 1. Oil leakage; 2. Clogged crankcase ventilation pipes; 3. Wear between the valve stem and valve guide; 4. Worn or damaged valve stem seals; 5. Incorrect installation of piston rings during maintenance, causing oil to enter the combustion chamber; 6. Piston rings stuck due to gumming or severely worn; 7. Improper selection of lubricating oil with excessively low viscosity; 8. Overfilling of lubricating oil. Engine oil is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. It is used for lubricating internal combustion engines.
