How to distinguish between National V and National VI?

[McLily]

National V refers to China 5, and National VI refers to China 6. The differences between National V and National VI are as follows: 1. Different sulfur content: The sulfur content limit of National VI standard gasoline is 50mg/kg, while that of National V standard gasoline is 10mg/kg. 2. Different implementation times: The National VI standard was implemented in December 2014, while the National V standard was implemented in December 2017. 3. Different durability mileage: Compared with National VI, National V has increased from 80,000 kilometers to 160,000 kilometers.

I spent some time figuring out the difference between China 5 and China 6 emission standards when buying a car recently. The most straightforward method is to check the vehicle's registration certificate. In the vehicle registration information section, if it states 'China V', it means China 5, and 'China VI' indicates China 6. My old car's registration certificate was labeled China 5, but when I replaced it with a new car last year, I specifically checked the environmental label on the windshield—a small round sticker printed with 'China 6'. You can also check online by following automotive public accounts and entering the VIN to display the emission level. Remember, the China 6 standard was implemented nationwide in 2019, so new cars manufactured after this date are mostly China 6. If buying a used car, don't just rely on the seller's word—always verify with the documents or an app to confirm the facts.

As someone who works on cars regularly, identifying China 5 and China 6 emission standards is straightforward. First, check the VIN code on the lower left corner of the windshield—scan it with the 12123 app, and the emission standard will be clear. In our toolbox, we also check the nameplate under the hood; if it's marked 'China VI' or the number '6,' it's definitely China 6. The OBD system in China 6 vehicles has been upgraded, and diagnostic checks can confirm parameter differences. The production date is crucial—China 6 was gradually introduced after 2017 and became standard after 2019. Don’t forget to check the environmental labels on the front and rear bumpers; the font size for 'China 5' and 'China 6' differs slightly and can be confusing. These methods are quick and accurate, helping you avoid buying the wrong car and facing driving restrictions.

To distinguish between China 5 and China 6, just check the vehicle license. The emission information is clearly marked in the emission section. It's also convenient to check via the VIN code. Download a car-related app, input the 17-digit code, and the results will be displayed immediately. China 6 is a higher standard, and almost all new cars after 2019 meet it. When purchasing, pay attention to the environmental label affixed to the front windshield. Incorrect identification may affect your vehicle usage costs.

I always advise my friends to check their vehicle's emissions because pollution affects the big picture. To identify whether it's China 5 or China 6, first visit the environmental protection department's website and enter the license plate number for authoritative and accurate results. China 6 has stricter restrictions to reduce exhaust emissions. When purchasing a car, always verify the environmental certificate and don't easily trust verbal promises. This helps protect the environment, reduces the risk of traffic restrictions, and jointly safeguards the blue sky.

When buying a car, I personally verified the emission standard. The salesperson said it was China 6, so I asked to see the environmental label on the windshield, which read 'China VI'. The registration information on the vehicle license also indicated China VI. I used mobile apps like WeChat mini-programs to check the VIN code, and it showed that China 6 vehicles are commonly produced after 2019. Careful verification avoids future difficulties with license plate registration or fines. Thorough checking is common sense, saving time and effort.
