How many more years can National IV emission standard vehicles be driven?

[McFernando]

National IV emission standard vehicles can still be driven for 8 years. The following is an introduction to the National IV emission standard: Introduction to National IV Emission Standard: Starting from May 1, 2018, the application for National III products was stopped, and only applications for National IV products were accepted. After July 1, 2018, no further announcements for National III models were issued. When applying for the announcement of National IV models, new specifications and models should be used to distinguish them from National III models. Since the new standard has already stipulated the technical route, National IV models no longer provide separate recommended technical solutions and should comply with the standard requirements. National IV Emission Standard Applicable Models: Motorcycles and mopeds are classified according to maximum design speed and displacement. Motorcycles refer to those powered by spark-ignition engines with a maximum design speed greater than 50 km/h or a displacement greater than 50 mL, as well as those powered by compression-ignition (diesel) engines with a maximum design speed greater than 50 km/h or a displacement greater than 50 mL for three-wheeled motorcycles.

Brothers driving China IV standard vehicles, don't panic too much. As long as your vehicle passes the annual inspection and is in good condition, you've got at least three to five good years left. It mainly depends on which city you're driving in—first-tier cities like Beijing, Shanghai, Guangzhou, and Shenzhen have stricter regulations, and restrictions might gradually roll out after 2027. Last time I helped someone check a used car, I found that Shenzhen already bans China IV diesel vehicles from entering the city center. Policies are more relaxed in second- and third-tier cities, where running for seven or eight years shouldn't be a problem—just make sure to maintain the catalytic converter well for easier emissions compliance during inspections. Keep an eye on local environmental bureau announcements. My neighbor Uncle Wang drives a China IV pickup in a small town, and this year, in its eighth year, it passed the annual inspection in one go.

Owners of National IV emission standard vehicles mainly worry about three things: policy changes, rising parts prices, and annual exhaust emission inspections. There's no nationwide ban yet, but tourist cities like Hangzhou and Chengdu might pilot high-emission zone restrictions by 2026. Maintenance costs will gradually increase - my friend found EGR valves for National IV cars cost 20% more than National VI parts when repairing. Exhaust treatment is crucial: remember to clean carbon deposits every 5,000 km and replace spark plugs every 20,000 km as manual suggests, which ensures smooth inspection. Data from our auto repair shop shows well-maintained National IV vehicles can generally run until around 2030.

Just checked the latest policy, diesel National IV vehicles can be used until 2030 at the latest, while gasoline cars may last even longer. Recently helped clients handle dozens of National IV cars and found that well-maintained vehicles can last at least three years longer than those with random modifications. Especially remind owners to check OBD fault codes every six months. Last time, a LaCrosse failed emissions due to an oxygen sensor error. Cities like Beijing, Shanghai, and Guangzhou may start restricting National IV vehicles by 2028, but in our county, you can drive them until scrappage without any issues. Prices of National IV cars in the used car market have dropped significantly. Buying one now for commuting is still cost-effective, but be prepared for 15% higher fuel consumption compared to new cars.

Driving a China IV emission standard vehicle is like using an old mobile phone – comfortable to use but destined to be phased out. A friend at the Ministry of Ecology and Environment revealed that a nationwide ban won't be implemented before 2030, but key cities will implement phased restrictions. Last year, I helped a client sell their China IV Passat – it still fetched 30,000 yuan after 12 years, proving maintenance is crucial. Every week I meet owners confused by driving restrictions. Shandong province has already banned China IV diesel trucks on national highways, though gasoline passenger cars can still use expressways. I recommend installing a vehicle diagnostics app to monitor the emission system – repair the EGR valve immediately if efficiency drops. In its final five years of use, maintenance costs for such vehicles may double compared to new cars.

I get asked this question five times a day. Here are three key takeaways: First, except for a few pilot zones, National IV gasoline vehicles can be used until 2028 without issues; second, set aside an additional 2,000 yuan annually for maintenance, mainly for cleaning the fuel system and replacing the catalytic converter; third, avoid buying property in restricted zones. A recent case I handled: a Suzhou-based owner insisted on adding fuel additive every month, and his 16-year-old Volkswagen Tiguan’s emissions were 15% below the standard during the annual inspection. However, a National IV sports car in the same city was advised to be scrapped due to severe carbon buildup from frequent traffic congestion. Focus on checking the ignition system and fuel delivery system—problems in these areas can directly cause emissions to exceed standards.
