Fully synthetic oil that has run for 12,000 kilometers needs to be replaced promptly. Generally speaking, the service life of fully synthetic oil is around 10,000 kilometers. If the vehicle is in good operating condition, running it for 12,000 kilometers is acceptable, but it is recommended that the owner replace the oil in a timely manner. Below is relevant information about automotive engine oil: 1. Types: There are three types of engine oil used in vehicles, namely mineral oil, semi-synthetic oil, and fully synthetic oil. Compared to mineral oil and semi-synthetic oil, fully synthetic oil has a more stable molecular structure, uniform molecular size, and offers excellent lubrication and oxidation resistance. 2. Functions: The primary role of engine oil is lubrication, reducing the friction coefficient between internal engine components during operation. It also repairs minor damage caused by friction and carries away metal particles generated by the friction between components.

Can Temporary License Plate 114 Check the Vehicle Owner?

Temporary license plate 114 can check the vehicle owner. Unregistered vehicles: Unregistered passenger vehicles that need to temporarily drive on the road should affix two temporary vehicle license plates simultaneously. One method is to paste it in the lower left or right corner of the front windshield inside the car, in a position that does not obstruct the driver's view. Another method is to paste it in the lower left corner of the rear windshield inside the car. Using fake temporary plates: Using fake temporary plates is considered using forged motor vehicle license plates, which is one of the serious illegal activities targeted by traffic management authorities. Traffic police can detain and tow away the motor vehicle and impose administrative detention of up to 15 days on the driver. For new vehicles on the road, checking whether the temporary plates are genuine and valid has become a routine task. On the back of the temporary plates, the vehicle's chassis number is indicated, along with the validity period, so trying to slip through is not feasible.

The reasons for loud fan noise when the car air conditioner is on are: 1. The air conditioner belt is loose or slipping; 2. The compressor is faulty; 3. There are foreign objects inside the blower or ventilation ducts. The solutions for loud fan noise when the car air conditioner is on are: 1. Replace the car air conditioner filter and remove any foreign objects; 2. Adjust the tightness of the compressor belt to increase friction or replace the belt; 3. Remove and inspect the compressor. The maintenance methods for the car air conditioner are: 1. Regularly clean the surfaces of the condenser and evaporator; 2. Pay attention to the operation of the compressor; 3. Close the external air circulation when there is a lot of dust in the air to reduce pollution of the air conditioner filter; 4. Regularly clean the air ducts and replace the air conditioner filter to keep the air inside the car fresh.

What to do when the ABS and anti-skid lights of Roewe RX5 come on simultaneously?

If they do not turn off or frequently illuminate, it is necessary to conduct a thorough inspection. It is recommended to visit a repair shop to use an automotive diagnostic computer to read the fault codes and perform a check. These two systems share sensor control units and related wiring, so the issue might be with a wheel speed sensor, the control unit, or the wiring. Below is an introduction to car maintenance: 1. Introduction to car maintenance: Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. 2. Scope of car maintenance: Modern car maintenance mainly includes the engine system (engine), transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. 3. Purpose of car maintenance: The purpose of car maintenance is to keep the car clean, maintain normal technical conditions, eliminate potential hazards, prevent faults, slow down the deterioration process, and extend the service life.

What Causes the Car Throttle to Fail to Accelerate?

The reasons why a car's throttle fails to accelerate are: 1. Clogged fuel line; 2. Blocked exhaust system; 3. Excessive carbon buildup in the throttle body. The functions of the throttle are: 1. Controlling the engine speed by adjusting the pedal pressure; 2. The throttle regulates the carburetor to determine the engine's output power. The working principle of the throttle is: When the accelerator pedal is pressed, it directly controls the throttle body, increasing the throttle opening, which allows more air to enter the engine. At this point, the ECU commands the fuel injection system to inject more fuel, thereby increasing the engine speed and enabling the car to accelerate. Solutions for abnormal noises when accelerating include: 1. Changing the engine oil; 2. Cleaning carbon deposits from the engine; 3. Replacing spark plugs; 4. Conducting a comprehensive inspection and repair of the vehicle.

What is the minimum mileage required for the first maintenance of a new car within three months?

The minimum mileage for the first maintenance of a new car is 3,000 or 5,000 kilometers. First maintenance items: The first maintenance of a car generally involves changing the engine oil and oil filter, and checking the working condition of the engine, such as whether all pipe connections are normal, whether there are any leakage points, whether the engine sound is normal, and whether there are any abnormal noises. Break-in period: The period from when a new car is first driven until its first maintenance is called the break-in period. During the break-in period, because the gears of the engine, transmission, etc. have not yet fully worn in smoothly, it is generally not advisable to drive too fast—absolutely do not exceed 100 km/h, and it is best not to exceed 80 km/h. During the break-in period, in addition to not exceeding 100 km/h, the engine speed should also not exceed 3,000 rpm. Avoid accelerating too aggressively, as it is not good for the engine's break-in. A proper break-in will result in fewer driving issues and better fuel efficiency in the future.
