Methods to check the national emission standard of a car: 1. Look at the car's windshield, check the back of the environmental compliance label sticker; 2. You can find the car's emission standard in the purchase documents, look for the vehicle conformity page or the page starting with the vehicle certification number, which contains the emission standard description; 3. There are some professional websites online where you can check the car's emission standard. Enter "motor vehicle environmental protection" in the search box and click on the environmental compliance vehicle query system, then input the vehicle information to check the emission standard; 4. The owner can take the vehicle registration certificate to the local DMV for inquiry, which can also check the vehicle's emission standard.

I've bought several cars before and found that the easiest way to check the emission standard is to look through the documents from when I purchased the vehicle. Check the purchase invoice and the factory certificate—they clearly state whether it's 'China IV' or 'China V' emissions. For new cars, you can also find this information on the environmental label stuck on the windshield—just scan the QR code with your phone for details. Before registering a used car, you can enter the license plate number on the local environmental bureau's website to check the records, which is quite convenient. Understanding emission levels is crucial when choosing a car—for example, China VI vehicles face fewer urban driving restrictions and are more fuel-efficient and eco-friendly. I often remind my friends not to rely on others' word—it's safest to check for themselves to avoid issues during annual inspections later. Over time, you'll realize these little tricks can save a lot of hassle, making the effort worthwhile.

How many kilometers can a Buick Envision still drive with 10% oil life remaining?

When the car displays an oil life of 10%, it indicates that the oil's health condition is insufficient, and continued driving is not recommended. The oil should be replaced promptly. If the oil life is nearly depleted, the oil quality may deteriorate significantly, becoming thicker or even spoiled. At this point, the oil loses its original performance, and continued driving will accelerate engine wear, ultimately causing engine damage. More relevant information is as follows: 1. Oil Life: Regarding oil life, it accurately refers to the engine's operating time. For conventional mineral oil, the engine operating time is generally 100 hours, while for basic full synthetic oil, it is 200-300 hours. This time frame represents the oil's lifespan. As for the oil change interval, many car owners decide on maintenance based on the vehicle's mileage. However, the actual maintenance time for oil also depends on driving conditions, vehicle condition, and oil type. Oil can be categorized into mineral oil, semi-synthetic oil, and full synthetic oil, and the validity period varies among different brands and grades of oil. 2. Replacement Interval: Conventional mineral oil is recommended to be changed every 5,000 kilometers, semi-synthetic oil every 7,500 kilometers or approximately 7-8 months, while full synthetic oil has a longer replacement interval and can be changed after driving 10,000 kilometers or about one year.

What Causes the Engine Fan Not to Rotate and the Engine Temperature to Be Too High?

The engine fan not rotating and the engine temperature being too high is caused by a ground fault at the fan connector in the engine cooling system. Function of the Cooling Fan: The car fan is controlled by a thermostat. The engine fan exists to prevent the engine water temperature from becoming too high. It consists of a sensor, an electric fan, a chip, and other components. When the engine water temperature exceeds 90 degrees, the sensor receives the temperature signal and activates the fan to lower the water temperature. Once the water temperature drops to the set level, the fan stops working. Cooling Fan Replacement Method: Open the car's engine hood, remove the intake pipe located above the cooling fan, and then use professional tools to unscrew the four screws on the fan bracket to remove the fan. Finally, correctly install the new cooling fan onto the new fan bracket and reattach the intake pipe.

Can You Directly Top Up Oil If the Car Engine Oil Is Insufficient?

You can directly top up oil if the car engine oil is insufficient. Faults caused by insufficient oil: "When the oil level is too low, it leads to poor lubrication on the friction surfaces of various engine components. Insufficient oil also reduces the engine's cooling and heat dissipation capability, causing internal overheating, which can further result in bearing bush burning and cylinder scoring. During driving, symptoms such as insufficient vehicle power and excessive oil consumption can be noticed." Symptoms of insufficient oil: The main symptom of engine oil burning is blue smoke coming from the exhaust pipe. Oil burning occurs when engine oil enters the combustion chamber through certain pathways and participates in combustion along with the air-fuel mixture. This is mainly caused by damaged piston rings leading to cylinder leakage, allowing oil to seep into the combustion chamber.
