What are the consequences of not changing engine oil after exceeding 10,000 kilometers?
1 Answers
If the car is driven for more than 10,000 kilometers without changing the engine oil, it will lead to oil degradation and failure, increased engine wear, and reduced cooling performance. Oil degradation and failure: Prolonged failure to change the oil will cause it to degrade and fail, affecting the engine's heat dissipation and lubrication. In severe cases, it may even clog the oil passages, leading to engine damage or complete failure. Increased engine wear: The accumulation of impurities in the oil increases friction, accelerating engine wear and potentially causing issues like cylinder scoring. Reduced cooling performance: The decline in the oil's cooling function can severely impact certain car components. Over time, some parts may become damaged or even burn out completely. Functions of engine oil: lubrication, auxiliary cooling, rust and corrosion prevention, etc. Engine oil ensures smooth relative sliding between the piston and cylinder, as well as between the crankshaft and bearings, reducing wear between these parts. Since fuel combustion in the engine generates heat, the oil carries heat back to the oil pan during operation, where it dissipates into the air, assisting the radiator in cooling the engine—thereby serving an auxiliary cooling role. Additionally, the oil forms a protective film on parts, shielding them from water, air, acidic substances, and harmful gases.
