What are the consequences of not changing the engine oil for 10,000 kilometers?
2 Answers
Hazards of not changing engine oil regularly: engine damage and reduced engine lifespan. Engine damage: If the engine oil is not changed for a long time, once it deteriorates and its performance declines, the lubrication performance of the bearings and the lubrication and cooling functions of the mechanical transmission components will be lost, thereby damaging the engine. Reduced engine lifespan: During the use of engine oil, it minimizes friction between gears and cleans small debris generated by friction. At the same time, engine oil in contact with air will also undergo oxidation. If the engine oil is not changed for a long time, the lubrication effect of the oil will be reduced, and small debris inside the engine cannot be discharged with the oil. This will cause scoring on the friction parts inside the engine, affecting the engine's power output and severely reducing its service life.
I once experienced delaying an oil change until 10,000 km as a regular car owner, and the vehicle's condition deteriorated significantly. The engine noise became noticeably louder, acceleration felt sluggish when pressing the gas pedal, and fuel consumption skyrocketed. After inspection at the repair shop, they said the oil had completely degraded, resembling sludge with extremely poor lubricity, causing severe wear on internal pistons and bearings. The repair cost nearly 3,000 yuan, almost requiring an engine replacement. The lesson is that delayed oil changes allow impurities to accumulate, impairing cooling efficiency. Prolonged neglect could lead to complete engine failure. Regular maintenance is fundamental investment in protecting your beloved car—don't follow my lazy example.
