What is the general service life of a car?

Different types of vehicles have different service lives. Small cars generally last for eight years, while large or heavy-duty vehicles typically have a service life of ten years. Methods to extend a car's lifespan and factors affecting its longevity are as follows: Methods to prolong a car's lifespan: Regularly change the engine oil. Maintain cleanliness and dryness inside the vehicle. Timely rust-proof maintenance for brakes, fuel supply, and other chassis components. Regularly wash the car to prevent corrosion in unclean areas. Promptly touch up scratches with paint. Ensure all necessary lubricants are sufficient and clean. Factors affecting a car's lifespan: Normal wear and tear during vehicle use is unavoidable. However, when wear and corrosion become severe, it leads to improper fitting between internal parts, resulting in poor sealing. In serious cases, it can cause issues like water leakage, oil leakage, vibration, and noise, severely impacting the performance of various car components and leading to damage that prevents normal operation. Non-metallic parts such as rubber and plastic in the car may experience varying degrees of aging over prolonged use or due to temperature effects, reducing material strength and causing cracking or fragmentation. Particularly when electrical components age, the car's electrical system may malfunction, significantly affecting normal vehicle operation.
When it comes to the service life of a car, I have deep personal experience after driving for over twenty years. The key lies in how you maintain and service it – my old Jialing motorcycle ran smoothly even after ten years. Generally, the designed lifespan is around 10 to 15 years, but it can actually exceed this with proper care: regular oil changes, checking tire wear, brake pad conditions, etc. Environmental factors play a big role – humid southern regions are prone to rust, while northern winters require antifreeze to protect the engine. Technological advancements are rapid, with newer models being more fuel-efficient and equipped with better safety features, prompting many to upgrade early. The scrappage policy has loosened; previously, cars were forcibly retired at 15 years, but now annual inspections determine their fate – with good maintenance, you can save money for several more years. Also, consider component aging, like belt breakage or suspension rust – replacing parts can extend its life. In short, take good care of your car, and its lifespan can be prolonged, saving money and being eco-friendly.
When I first bought a car, I was particularly concerned about this issue. Research showed that the average lifespan of a car is 10 to 15 years. Designers set overall lifespan targets, such as running 200,000 kilometers. However, the actual duration depends on driving habits: steady highway speeds reduce engine wear, while city traffic congestion accelerates deterioration. Proper maintenance, like frequent car washing and timely air filter replacements, can extend usage. Technological advancements give new cars a clear advantage; the emergence of electric vehicles has caused older fuel cars to depreciate rapidly. From an economic perspective, a new car loses half its value in the first two years, after which repair costs rise—it becomes cost-effective to replace the car when maintenance expenses exceed the monthly payments for a new one. The rise of the used car market makes maintenance records and mileage key factors when buying older cars. Environmental factors, such as salt corrosion in coastal areas, can shorten a car's lifespan. In summary, with good maintenance strategies, a car can last longer.
