What is the lifespan of domestic engines in kilometers?
2 Answers
Domestic engines typically have a lifespan ranging between 200,000 to 300,000 kilometers. Ways to extend engine lifespan: Perform regular maintenance, use high-quality engine oil and oil filters. Replace transmission oil periodically with quality spark plugs to prevent clogging. Regularly clean the fuel system, maintain the radiator, and use premium lubricants. Adhering to these practices can effectively prolong the engine's service life. Factors affecting engine lifespan: The actual lifespan of an engine depends on individual driving habits, maintenance routines, and environmental conditions among other comprehensive factors. Ensuring the engine operates at normal temperature is crucial for optimal performance in terms of operational resistance, wear and tear, and stability among components.
Having repaired cars for over a decade, I've handled quite a few domestic engines. Nowadays, mainstream models like Changan's Blue Core and Geely's Thor can easily clock 200,000 kilometers with proper maintenance. Just recently, I worked on a 2014 Haval H6 that was still running smoothly at nearly 380,000 kilometers on the odometer. The key is regular oil and filter changes every 5,000 km, periodic carbon deposit cleaning, and keeping the radiator clean. In cities with heavy traffic, I recommend shortening the maintenance intervals. I've seen many owners neglect coolant changes, resulting in cylinder scoring at just over 100,000 km. With proper care, 200,000 km is really just the starting point—I'm confident about that.
