What happens if a vehicle is low on engine oil?

Insufficient engine oil in a vehicle can lead to cylinder scuffing, poor lubrication, and increased wear on engine components. The functions of engine oil are: 1. Lubrication to reduce wear; 2. Assisting the radiator in cooling the engine; 3. Flushing away dirt from engine parts; 4. Cushioning the load on connecting rods and crankshaft bearings; 5. Forming a seal between piston rings and pistons to reduce gas leakage and prevent the entry of external contaminants. The method for changing engine oil is: 1. Run the engine until it reaches operating temperature; 2. Place an old oil container under the oil pan and loosen the drain plug; 3. Move the oil container under the oil filter and unscrew the filter element; 4. Apply engine oil to the gasket of the filter element; 5. Pour the new oil into the oil pan.
Running low on engine oil is really frustrating. Engine oil is the lifeblood of your car's engine, responsible for lubricating all moving parts to reduce friction and prevent overheating. If you drive with insufficient oil, friction increases dramatically, accelerating component wear and causing the engine to overheat or even fail quickly. At best, you might hear strange noises and see blue smoke; at worst, the engine could seize entirely, with repairs costing upwards of ten thousand yuan. I once encountered this issue while helping a friend check his car—his old Ford had worn-out piston rings due to long-term neglect of oil changes, and it took ages to fix. To avoid such problems, I recommend checking the dipstick every 5,000 kilometers or three months to ensure the oil level stays between the min and max marks. Oil consumption speeds up in summer heat, so extra vigilance is needed.
