How Long Can National V Diesel Vehicles Continue to Be Driven?

[DeEllie]

With the implementation of the National VI standard, National V diesel vehicles are not affected in normal use, with no driving bans or restrictions. They can continue to be driven indefinitely. Details are as follows: 1. Advantages: Diesel engines offer high torque and excellent fuel efficiency. The working process of a diesel engine shares many similarities with gasoline engines, with each cycle also going through intake, compression, power, and exhaust strokes. However, since diesel fuel has higher viscosity than gasoline, is less volatile, and has a lower auto-ignition temperature, the formation of the combustible mixture and ignition method differ from gasoline engines. 2. Differences: The mixture in a diesel engine's cylinder is ignited by compression rather than spark. During operation, only air enters the cylinder. When compressed to the maximum, the air temperature can reach 500°C-700°C, and the pressure can reach 40-50 atmospheres.

I think China V diesel vehicles can still be driven for many years. After all, the China V standard was implemented in 2017, and it's only 2023 now, so many vehicles are still relatively new. I've been driving this type of vehicle for a long time myself. With proper maintenance and a well-functioning engine, it's no problem to drive for over a decade. Of course, policies may change. In big cities like Beijing and Shanghai, there are already restricted zones, mainly targeting older vehicles. China V diesel vehicles are largely unrestricted in suburban and rural areas, so you can use them without much worry. However, it's important to regularly check the exhaust emissions during annual inspections—if they exceed the standards, repairs or replacements will be needed. In short, keeping the vehicle in good condition and staying updated on local traffic regulations, you can expect to drive it for about 10 more years without too much concern. The future trend is the widespread adoption of new energy vehicles, so you can gradually prepare for the transition, but it won't happen overnight.

In my opinion, how long a China V diesel vehicle lasts depends largely on how well you maintain it. I've worked with many diesel vehicles, and as long as you keep up with routine maintenance—like changing the oil on time, cleaning the fuel injectors, and checking the DPF system (the one in the exhaust pipe)—a well-maintained vehicle can easily last 15 years. Don’t ignore minor issues, such as a clogged filter affecting performance; fixing them promptly prevents bigger problems. The costs aren’t high either, and knowing some basic maintenance can save you a lot of money. Policy-wise, while the country is pushing for China VI standards, China V vehicles can still operate normally in smaller cities, with only high-emission vehicles facing restrictions in major cities. In the used car market, China V vehicles hold their value well, so take your time driving them—there’s no rush to upgrade. The money saved can be better spent elsewhere. As long as the chassis doesn’t rust through prematurely, every mile driven is worth it.

Regarding how long a China V diesel vehicle can be used, I believe it largely depends on policy orientation. The government sets emission standards for environmental protection. While China V is relatively outdated, non-commercial vehicles can still operate for many years. Major cities may gradually impose restrictions, such as limiting driving hours in downtown areas, but regulations are more lenient elsewhere. The vehicle itself has a decent lifespan—just ensure regular exhaust inspections. I know people still driving 2015 diesel pickup trucks without issues, even on long trips. In the long run, diesel vehicles will be replaced by new energy, but China V models can still serve well for a while. Don’t be alarmed by rumors; just evaluate local regulations and keep using it.
