How Many Kilometers Should a Car Be Serviced Generally?

What are the mirrors on both sides of the car called?

The mirrors on both sides of the car, that is, on the left and right sides of the driver and co-driver seats, are called rearview mirrors. They are used to observe the road conditions behind the car during reversing and to monitor the surroundings of the vehicle while driving. Below is some relevant information about rearview mirrors: 1. Rearview mirrors are one of the important safety components of a motor vehicle's body, used to observe the road conditions behind the car during reversing and to monitor the surroundings of the vehicle while driving. Currently, the reflective films of rearview mirrors in domestic vehicles are generally made of silver and aluminum, with some using chromium as the material. 2. Currently, in foreign countries, chromium mirrors have replaced silver and aluminum mirrors for vehicle rearview mirrors. Rearview mirrors are tools that allow the driver to directly obtain external information about the rear, sides, and lower parts of the car while seated in the driver's seat. For the convenience of the driver's operation, to prevent traffic safety accidents, and to ensure personal safety, all countries require that vehicles must be equipped with rearview mirrors, and all rearview mirrors must be adjustable in direction.

What is the optimal position for adjusting car rearview mirrors?

The correct positions for adjusting car rearview mirrors are as follows: 1. Center rearview mirror: The center rearview mirror helps drivers quickly assess road conditions behind them and maintain a safe distance from vehicles at the rear. Adjust the center mirror to be parallel with the horizon line, positioning the horizon at the center 1/2 point of the mirror surface. The mirror should slightly face the driver to ensure clear visibility of vehicles directly behind. 2. Left side mirror: Since the left mirror is closer to the driver's side, the blind spot is smaller and the field of view wider, requiring less adjustment than the right mirror. Similarly, adjust the horizon to the center 1/2 position of the left mirror while keeping 1/4 of the car body visible in the mirror. Showing too little of the car body makes it hard to see vehicles close to the rear; showing too much makes it difficult to clearly see vehicles that are partially parallel. 3. Right side mirror: Being on the right side, the driver's blind spot is larger, requiring different adjustment angles than the left mirror. Here, adjust the horizon to the 2/3 position of the right mirror while maintaining 1/4 of the car body visible.

How Long Can Opened Motor Oil Be Stored?

Opened motor oil can be stored for six months to one year. Below are precautions for using motor oil: 1. Gasoline engine oil cannot be used in diesel engines: Special gasoline engine oil should not replace diesel engine oil to avoid accelerating wear in diesel engines. Gasoline engine oil and diesel engine oil should, in principle, be used separately. Only when the automobile manufacturer provides substitution instructions or the oil is labeled as suitable for both gasoline and diesel engines can it be substituted or used within the specified grade range. 2. Motor oil viscosity should be as low as possible: Under the premise of ensuring reliable lubrication for the engine, the viscosity of the oil should be as low as possible. High-viscosity oil is only suitable for severely worn engines or for use in southern summers. Using excessively high-viscosity oil will increase the resistance during engine operation, thereby increasing fuel consumption. 3. Adhere to the principle of economy and practicality: When selecting the grade of motor oil, high-grade oil can be used in engines with lower requirements, but excessive downgrading is not economical. Never use lower-grade oil in engines that require higher-grade oil, as this may lead to premature engine wear and damage.

How Long Does It Take to Get a Temporary License Plate?

Temporary license plates can usually be obtained on the same day of application. When using temporary plates, it is important to adhere to traffic regulations, as they hold the same legal validity as regular license plates. Additionally, be mindful of the expiration date of the temporary plates to avoid using them past their validity period. Here is some information about temporary license plates for vehicles: 1. Temporary license plates are issued by the vehicle management department of the public security authorities when a vehicle has not yet been officially registered due to pending procedures. The validity period of a temporary license plate generally does not exceed thirty days, and its use is limited by both time and region. 2. There are four types of temporary license plates: temporary plates for use within an administrative district, temporary plates for use across administrative districts, temporary plates for testing purposes, and temporary plates for special types of motor vehicles.

How is the annual inspection time for vehicles regulated?

National regulations on vehicle annual inspection time: 1. For passenger transport vehicles, inspections are required once a year within the first 5 years, and every 6 months thereafter. 2. For trucks and large or medium-sized non-commercial passenger vehicles, inspections are required once a year within the first 10 years, and every 6 months thereafter. 3. For small and micro non-commercial passenger vehicles, inspections are required once every 2 years within the first 6 years, once a year thereafter, and every 6 months after 15 years. The following is an introduction to vehicle annual inspections: Vehicle annual inspection refers to a mandatory test for every vehicle that has obtained an official license plate and registration certificate. The purpose is to promptly eliminate potential safety hazards, encourage better vehicle maintenance, and reduce the occurrence of traffic accidents.

How to Check the Production Date of Michelin Tires?

Method to check the production date of Michelin tires: Locate the DOT marking on the sidewall of the tire. The last four digits following this marking represent the production date of the Michelin tire. The first two digits indicate the week of production within the year, and the last two digits indicate the production year. Below is an introduction to the functions of car tires: 1. Support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions. 2. Transmit traction and braking torque, ensuring good adhesion between the wheels and the road surface to improve the vehicle's power performance, braking performance, and passability; work together with the car suspension to mitigate impacts during driving and dampen the resulting vibrations. 3. Prevent severe vibrations and early damage to car components, adapt to the vehicle's high-speed performance, reduce driving noise, and ensure driving safety, handling stability, comfort, and energy efficiency.
