Why Do Cars Easily Burn Engine Oil?

[DiHarrison]

The primary source of oil burning is the engine block. The contact surfaces within the cylinder—the cylinder walls and pistons—develop increased gaps and poor sealing due to various reasons, causing oil to seep into the combustion chamber and resulting in oil burning. Below are relevant details: 1. Function of Engine Oil: Engine oil, also known as engine lubricant, lubricates and reduces friction to ensure smooth operation of engine components. It also aids in cooling: during engine operation, high temperatures are generated. When the oil reaches the operating parts, it absorbs heat and carries it away, assisting in heat dissipation. 2. Maintenance Tips: Regularly maintaining the engine according to the recommended mileage will extend its lifespan. If the oil is too dirty, impurities in the oil can accelerate wear in the engine cylinders, necessitating timely oil replacement.
