After the implementation of China 6, there are several specific ways to handle China 5 vehicles. Selling: Sell to consumers through strategies like cross-regional sales and low prices. Engine Replacement: If China 5 vehicles are banned nationwide, they can be returned to the factory to directly replace the engine with a China 6 one. The removed China 5 engines can be used as spare parts for current China 5 vehicles in the market. Below is extended information about China 5 and China 6: China 5: China 5 refers to the fifth phase of motor vehicle pollutant emission standards. The emission control level of China 5 is equivalent to the fifth phase emission standard currently implemented in Europe. China 6: China 6 refers to the sixth phase of national motor vehicle pollutant emission standards. On December 23, 2016, the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine issued the 'Limits and Measurement Methods for Emissions from Light-duty Vehicles (China 6)', which was implemented from July 1, 2020.

I've been thinking about this a lot lately. When China 6 standards were first implemented, everyone was genuinely worried that China 5 vehicles would be scrapped directly. In reality, our existing China 5 vehicles can continue to operate normally without any issues regarding annual inspections or insurance. However, if you're considering buying a new car, you need to think carefully - many cities now mandate China 6 standards for new vehicles, and transferring second-hand China 5 vehicles to certain restricted areas can be quite troublesome. My neighbor sold his China 5 car to a third-tier city last year for 10% more than the local price - I'd recommend checking regional policy differences in advance. If you plan to keep driving for another five or six years, just maintain the engine regularly and pass the emissions test, then there's nothing to worry about.

Last month I accompanied my friend to sell his China V emission standard car in the used car market, and found the market situation more stable than expected. As long as it's not in strictly regulated cities like Beijing, Shanghai, Guangzhou or Shenzhen, China V vehicles still circulate smoothly, but their resale value has indeed dropped by about 15%. From experience, older cars turn out to be more cost-effective, since their depreciation has bottomed out. The mechanic told me the key lies in the exhaust treatment system - regular cleaning of the three-way catalytic converter can effectively avoid exceeding emission standards. There are also smart tricks for fuel-efficient daily driving: avoiding sudden acceleration to reduce carbon buildup, and switching to low-ash engine oil shows noticeable effects. Of course, we'll have to face the new energy trend when changing cars in the future, so early planning never hurts.

When the China 6 emission standard was first implemented, I also worried about my China 5 compliant car. After driving it for two years, it turned out to be completely unaffected. The vehicle management department clearly stated that purchased vehicles would still follow the original standards, so they can still be driven on the road as usual. The real issue to pay attention to is the transfer restrictions. For example, my cousin faced obstacles when trying to register his car in Hangzhou and eventually opted to replace it with a new energy vehicle to get the subsidy. Considering the policy transition period, continuing to use the car is entirely feasible, but it's advisable to shorten the car replacement cycle from five years to three. Regarding maintenance, the mechanic emphasized checking the oxygen sensor, as aging of this component can easily lead to emission non-compliance, and replacing it only costs a few hundred yuan.
