06-year-old cars comply with the National II standard. More information about automotive emission standards is as follows: 1. China's second-phase automotive emission standard is equivalent to the Euro II emission standard, meaning the pollutant content in the exhaust is equivalent to Euro II levels. According to the "Announcement on Implementing the National Second-Phase Motor Vehicle Emission Standards" issued by the Environmental Protection Administration, all heavy-duty vehicles undergoing type approval must meet the national second-phase type approval emission limits equivalent to Euro II standards starting from September 1, 2003. This marks a new stage in China's motor vehicle emission pollution control. 2. From July 1, 2004, all newly approved light-duty vehicles must comply with the National II standard, and the application and approval of light-duty vehicle models meeting the National I standard equivalent to Euro I standards were discontinued. 3. According to Announcement No. 5 of 2006 by the State Environmental Protection Administration "Announcement on Publishing New Motor Vehicle Models and Engine Types Meeting the National Second-Phase and Third-Phase Motor Vehicle Emission Standards", the National III standard mainly applies to light-duty gasoline and diesel vehicles under 3.5 tons, equivalent to the Euro III standard, with a nationwide implementation date of July 1, 2007.

I've been driving for over 20 years. Most cars from 2006 were compliant with China II emission standards. When buying cars back then, manufacturers were in a transition period - the China III standard wasn't officially implemented until 2007, so virtually all 2006 models were China II. My own 2006 Focus served me well for many years, always passing emission tests, though with noticeably heavier exhaust fumes due to carbon buildup in older engines - you could see the smoke upon startup. Regular maintenance like frequent oil changes and spark plug cleaning can extend its lifespan, but pollution remains higher. I recommend checking the environmental label on your vehicle registration to confirm, as some late-2006 models might have been upgraded to China III. Maintaining older cars gets expensive, and with many cities now restricting China II vehicles, switching to a new energy vehicle might be more economical and environmentally friendly.

I'm particularly concerned about environmental issues and have studied the history of automotive emissions. Vehicles produced in 2006 generally meet China II standards due to technological limitations of that era, resulting in inadequate exhaust treatment and higher emissions. It's unsettling to see older cars emitting smoke on the road, contributing to urban smog. I recommend owners check their vehicle's nameplate or VIN code to verify emission standards. If continuing to use such vehicles, regular exhaust testing is advised to ensure the catalytic converter functions properly. For those with budget, upgrading to China III compliant vehicles can reduce fine risks and provide cleaner air for children. With growing environmental awareness, green commuting has become a priority when driving.

Most cars from 2006 are compliant with China's National II emission standards. Driving such older vehicles tends to cause issues like excessive engine carbon deposits and frequent illumination of the emission fault warning light. I've seen many cases where clogged oxygen sensors lead to exhaust emissions exceeding standards. During maintenance, pay attention to replacing the air filter and inspecting fuel injectors to maintain combustion efficiency; poor emissions can affect annual inspection pass rates. Simply put, before purchasing a used car or for personal use, it's best to check specific model data online to confirm details—don't be careless.

How many days does it usually take to practice for Subject 2 before taking the test?

Subject 2 consists of 24 class hours, with a maximum of four class hours per day. Currently, the required class hours for each subject in the C1 driver's license training and examination are as follows: Subject 1: 12 hours, Subject 2: 26 hours (including 2 hours of theoretical knowledge), Subject 3: 40 hours (including 16 hours of theoretical knowledge). Among these, the practical training hours for Subject 2 (five mandatory tests) and Subject 3 (long-distance and road tests) are both 24 hours, accounting for the majority of the total 78 class hours. Generally, it takes about 10-15 days of study before taking the Subject 2 test. In fact, there is no time limit for how long you need to study for Subject 2. You can take the test as long as you have mastered the content. Typically, most people take about 10-15 days to prepare, but the exact duration depends on the individual's learning pace.

When is the Best Time to Refuel?

It is generally advisable to refuel when the fuel level drops to one-quarter of the tank's capacity, and it's best to fill up only about two-thirds of the tank. This might differ from the common practice of filling the tank completely, but there are valid reasons for this approach. Refueling when the fuel level reaches one-quarter ensures that the vehicle won't run out of fuel unexpectedly. Additionally, the fuel pump inside the tank may become exposed to air if the fuel level is too low, leading to insufficient cooling and potential damage to the pump. Repairing a damaged fuel pump can be quite costly. As for why it's recommended to fill only two-thirds of the tank, gasoline is a volatile substance. Overfilling the tank can cause gasoline vapors to increase the internal pressure, leading to fuel leakage. This not only wastes gasoline but also increases unnecessary fuel expenses. Moreover, in the presence of an ignition source, this could easily lead to a fire, potentially causing severe injuries or fatalities, resulting in significant losses.

Will the warranty still be valid if maintenance is not done at a 4S shop?

You will not be able to enjoy the warranty. New cars generally come with a three-year or 100,000-kilometer whole vehicle warranty, whichever comes first. If a new car within the warranty period is not maintained or repaired at a 4S shop, once any quality issues arise, the car dealer will refuse to provide warranty benefits on the grounds that "maintenance or repairs not performed at a 4S shop or designated service station cannot enjoy the warranty." In fact, the car dealer's approach is not without reason. Owners cannot guarantee that the vehicle's quality issues are not caused by improper repairs at sites other than 4S shops. Therefore, it is still advisable for new cars to be repaired at 4S shops. Although the labor service fees are slightly more expensive, the quality of repairs at 4S shops is still guaranteed. The whole vehicle warranty means that if various parts are confirmed to be damaged due to product quality issues rather than human factors, they can be replaced or repaired for free. For example, if components like the tachometer or air conditioner develop problems within the warranty period or the specified mileage, they can be repaired for free.

How many milliliters of fuel additive should generally be added?

Generally, 300ml of fuel additive is added, but in reality, it should be analyzed based on the actual situation. For example, if the fuel tank has a larger capacity, more fuel additive needs to be added. Fuel additive is unnecessary for new cars with less than 20,000 kilometers of mileage. For vehicles exceeding 20,000 kilometers, it should be added as needed. Long-term use of fuel additive is harmful to the engine, and excessive use can increase carbon deposits in the combustion chamber, even leading to engine knocking or detonation, and worsening vehicle exhaust emissions. The functions of fuel additive are: 1. Remove carbon deposits from the car; 2. Reduce abnormal wear of the engine; 3. Improve atomization efficiency; 4. Reduce vehicle exhaust emissions; 5. Extend the service life of the car engine; 6. Clean the fuel system.
