How Many Years Can a Private Car Be Used?

There is no usage limit for small private cars, but they will be guided to scrap after reaching 600,000 kilometers. Below are the national scrapping regulations: First, whether a car is scrapped is related to annual inspections: Before 2013, vehicles over 15 years old were mandatorily scrapped. After 2013, although there is no mandatory scrapping, vehicles over 15 years old must undergo inspections twice a year, and those over 20 years old must undergo inspections four times a year. If they fail to pass, they will be forced to scrap. Second, the state restricts the driving of over-limit motor vehicles through environmental regulations: The state also uses environmental regulations to limit the driving of over-limit motor vehicles. For example, if a vehicle fails the annual exhaust test, it will be mandatorily scrapped. Additionally, there are restrictions on vehicles with low emission standards. For instance, in major cities like Beijing and Shanghai, vehicles with National I and National II emissions are not allowed to drive in urban areas. As emission standards become stricter, these restrictions will become more stringent. Even National IV and National V vehicles today may only be allowed to drive in suburban areas decades later.

I've specifically looked up the policies before. Currently, there's no mandatory scrapping age for private cars, but vehicles reaching 600,000 kilometers will be guided toward retirement. Realistically speaking, it's rare to see sedans on the road that are over 15 years old. A friend of mine has a car that's 12 years old, and it's getting harder to pass the annual inspections each year—the emissions test feels like going through hell, with the catalytic converter replaced several times. After 10 years, many parts start aging; cracked rubber chassis components and transmission oil leaks are common. New cars nowadays generally aren't as durable as older models, with more plastic parts prone to rattles. If you take exceptional care of your car—regularly replacing all rubber bushings, parking it in a garage to avoid sun exposure—it might theoretically last 20 years, but the accumulated repair costs could easily add up to the price of a new car.

It depends on how you use it! My old Accord is already 18 years old with 270,000 kilometers on the odometer. The key is maintenance: I change the engine oil and oil filter every 5,000 kilometers, replace the timing belt at 100,000 kilometers, and renew rubber hoses every five years. Underbody anti-rust coating is very effective, especially in humid southern regions. However, passing the annual inspection is quite troublesome now—last year, it took two attempts to pass the emissions test. Many friends replace their cars after 10 years, mainly because the electronic systems become outdated, lacking features like CarPlay. If you only use it for city commuting and don’t chase new features, an old car can easily last another decade. Just remember to avoid yellow-label vehicle restricted zones, as some cities impose restrictions on cars over 15 years old.

My experience is that the three major components determine a car's lifespan. With proper maintenance, an engine can easily run 500,000 kilometers, but the transmission often fails first, especially dry dual-clutch transmissions. The most extreme case I've seen was a taxi driver whose 1.6L naturally aspirated engine kept running even after the odometer showed it should be scrapped. After 15 years of actual use, you should prepare for major repairs as aging wiring becomes dangerous - my relative's car once caught fire due to short circuits. Modern cars use more plastic parts and have inferior rustproofing compared to twenty years ago, making new cars less durable.
