Maintenance at 20,000 kilometers is typically the third maintenance for a car, which is a major service. The routine items for the third car maintenance include the following: 1. Oil and oil filter replacement: Changing the oil and oil filter is essential. Under the harsh conditions of high temperature and high pressure inside the engine, the shelf life of oil is significantly shortened, and its performance greatly declines. Over time, it fails to protect the engine. The oil filter prevents impurities from mixing into the oil, which can cause oxidation, leading to the formation of sludge and clogging the oil passages. Both the oil and oil filter should be replaced simultaneously. 2. Air filter and cabin air filter: The air filter needs to be replaced at this stage. If it wasn't replaced during the 10,000-kilometer maintenance, it must be replaced at the 20,000-kilometer service. The air filter prevents dust and particles from being sucked into the engine during the intake process. If the filter is not cleaned regularly, it can lead to dust entering the engine, causing abnormal wear on the cylinder walls. 3. Spark plugs: If the car uses standard material spark plugs, preparations should be made to replace them at 20,000 kilometers. Spark plugs directly affect the engine's acceleration performance and fuel consumption. When you feel a lack of engine power while driving, maintenance should be performed. The lifespan of spark plugs varies depending on the material.

What documents are needed for car registration?

The required documents include: vehicle certification, purchase invoice, and compulsory traffic insurance policy (commercial insurance can be purchased after registration). In Beijing, Shanghai, and Guangzhou, proof of vehicle purchase quota is also required. Before going to the vehicle management office for registration, you should make three copies of your ID card, temporary residence permit (if any), vehicle certification, purchase invoice, and compulsory traffic insurance policy for backup. The process for new car registration is as follows: 1. Obtain the vehicle certification: The vehicle certification is very important and is required for registration. Currently, some car 4S stores delay providing the vehicle certification, which may postpone the registration. Therefore, you should communicate with the 4S store frequently and firmly to obtain the certification as soon as possible. 2. Keep the triplicate purchase invoice: After purchasing the car, the 4S store will issue a triplicate purchase invoice. Be sure to keep it safe as it will be needed for subsequent registration. The invoice has red, yellow, and blue copies. Generally, the red and yellow copies need to be submitted, while the yellow copy should be kept by yourself. 3. Pay the vehicle purchase tax and obtain the tax certificate: After purchasing the car, you should pay the vehicle purchase tax as soon as possible. You can usually do this at the nearest vehicle management office. After successfully paying the tax, you will receive the tax certificate, which should be kept safe. 4. Prepare various documents: Prepare the original ID card and copies (make several copies for backup). Non-local residents need to provide the original and copies of the temporary residence permit (organizations need to provide the original and copies of the organization code certificate). 5. Register and inspect the vehicle at the vehicle management office: Once all the procedures are complete, you can go to the vehicle management office to apply for a license plate. First, a specialized traffic police officer will inspect the vehicle, mainly checking the vehicle identification code, appearance, and warning triangle. Prepare these in advance. 6. Choose the vehicle license plate number: After the inspection, you can go to the vehicle management office hall to select a license plate number. Generally, there are two options: self-selection and random selection. Additionally, most regions now offer online license plate selection. 7. Pay the fee and wait for the license plate: After selecting the number, pay the fee and wait for the license plate. It usually takes three to five working days to receive the license plate.

Should the Buick Regal use 5W30 or 5W40 engine oil?

Buick Regal uses 5W30 engine oil. Compared with 5W40, 5W30 has the same low-temperature fluidity but differs in high-temperature performance. 5W40 has higher viscosity, providing better high-temperature protection and sealing performance. However, the increased viscosity results in greater engine running resistance and higher fuel consumption. For the Regal's engine, 5W30 engine oil is more suitable. 5W refers to the range of ambient temperatures in which the oil can be used, indicating its viscosity grade. It can be used in extremely cold regions during winter, with temperatures ranging from -40°C to -10°C. This viscosity grade of oil is relatively thin, with excellent low-temperature fluidity, resulting in relatively low running resistance at low temperatures and making it easier to start the car. Key factors to consider when choosing engine oil: The selection of engine oil should be based on the requirements of the engine. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. Precautions for changing engine oil: The engine must be preheated before draining the oil. At this time, the oil is thinner and flows more easily, helping to carry away impurities and ensuring thorough drainage. Remember not to drain the oil when the engine is cold, and replace the oil filter simultaneously. The old oil filter may be clogged with impurities, and a blocked oil filter can slow down oil flow and reduce engine lubrication. The amount of oil added should be measured, and for some vehicles, the oil level can be checked with a dipstick to ensure it is within the proper range.

How many points are deducted for not using the turn signal when making a U-turn?

According to the "Road Traffic Safety Law", not using the turn signal when making a U-turn results in: 1 point deduction; fine: 100 yuan. Other situations that result in a 1-point deduction include: not using lights as required; not meeting vehicles as required; motor vehicles carrying cargo exceeding the prescribed length, width, or height; motor vehicles driving on the road without inspection qualification marks, insurance marks, or without carrying the vehicle license and driver's license. Article 57 of the Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China states that motor vehicles shall use turn signals as follows: When turning left, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn, the left turn signal shall be turned on in advance; When turning right, changing lanes to the right, returning to the original lane after overtaking, or parking by the roadside, the right turn signal shall be turned on in advance. Turn signals: Must be turned on when the vehicle is turning, flashing intermittently to alert vehicles and pedestrians around. The timing of turning on the turn signal should be well controlled, and it should be turned on about 30 to 100 meters before the turning point. Situations where U-turns are allowed: Intersections with U-turn signs: If there is a clear U-turn sign at the intersection, a U-turn can be made; if there is a U-turn signal light, the U-turn must be made according to the signal light. If there is no signal light, a U-turn can be made based on the specific situation, provided it does not hinder other vehicles or pedestrians. Intersections without explicit prohibition of U-turns or left turns: If there is no explicit sign prohibiting U-turns, a U-turn can be made. "No explicit prohibition of U-turns" means that as long as there is no "No U-turn sign," "No left turn sign," or the center line is not solid, a U-turn can be safely made. Yellow grid lines also allow U-turns: Yellow grid lines are actually no-parking grid lines painted at intersections prone to temporary parking congestion, important unit entrances, and other locations where they are needed. Any vehicle stopping on the no-parking grid line (including waiting for traffic lights) is a violation. Although vehicles cannot stop in the yellow grid line area, U-turns are allowed. As long as there is no central isolation barrier, the yellow grid line is equivalent to "U-turn allowed." Intersections with U-turn signal lights: This is easy to understand. If there is a U-turn signal light, you must follow the signal light and only make a U-turn when it is green. When "No left turn" and "U-turn allowed" signs appear together: U-turns are allowed but left turns are prohibited. However, "No U-turn" is not the same as "No left turn." Things to note when making a U-turn at an intersection: Observe the road markings. If it is a solid line, U-turns are not allowed under any circumstances, and you should continue driving to find a suitable place for a U-turn. If there is a "No left turn" sign ahead, even if there is no mention of prohibiting U-turns, U-turns cannot be made at this intersection because the actions of left turns and U-turns are very similar, and a U-turn must involve a left turn first. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, you cannot make a U-turn at this intersection. When making a U-turn, you must yield to vehicles going straight and only make the U-turn without interfering with their normal driving. Otherwise, you will bear full responsibility for any accident. Generally, near the intersection stop line, lanes are marked with guiding arrows for vehicles to choose lanes. The leftmost lane is not always marked with a left-turn arrow. On some roads, if there is a straight arrow, even if there are no explicit signs prohibiting U-turns, U-turns are not allowed.
