On car tires, 'INSIDE' indicates the inner side, serving as a directional marking for tire installation. Below are specific methods for tire maintenance: 1. Regularly check tire pressure: Tire pressure is a crucial factor affecting tire lifespan. It should neither be too high nor too low; always inflate according to the vehicle's specified pressure. In summer, try to keep the pressure slightly lower. In winter, ensure tires have slightly higher pressure than in summer due to thermal expansion and contraction. 2. Inspect wear patterns: Some vehicles may experience uneven tire wear. Frequently check the inner side of tires for abnormal wear, focusing on whether tread depths on both sides are consistent. 3. Promptly remove foreign objects: Debris in tire treads poses potential hazards and may eject during driving. Strive to keep tires clean. 4. Schedule regular wheel alignment: If the vehicle pulls to one side or exhibits abnormal steering, perform wheel alignment promptly to prevent further tire issues. Four-wheel alignment ensures even force distribution across all tires, preventing excessive wear.

As an experienced auto mechanic, I can explain the 'inside' marking on tires simply: it indicates the inner side direction of the tire. This is particularly crucial for asymmetrically designed tires, as their tread patterns and drainage grooves are directional. The 'inside' marking must face the vehicle's interior during installation; otherwise, it can lead to uneven tire wear, reduced wet-road traction, and even increased fuel consumption. I've encountered numerous customers complaining about noise or vibration issues, only to discover their tires were mounted incorrectly during inspection. I recommend both car owners and technicians carefully check this marking when installing new tires and make it a habit to ensure safety. During routine maintenance, it's also wise to verify the tire direction – after all, tires are the first line of defense against the road surface, and being meticulous can prevent many subsequent problems.

I'm an ordinary car owner with over a decade of driving experience. The 'inside' marking on tires indicates which side should face inward during installation, especially for asymmetric tread patterns. If installed incorrectly, you'll feel unstable handling. I once experienced this firsthand – new tires showed uneven wear on one side soon after installation, only to discover they were mounted backwards. After correction, the driving became much smoother. To avoid such issues, always supervise technicians to ensure the 'inside' mark faces inward during tire changes, or check it yourself afterwards by squatting down. This is crucial for daily driving, particularly on slippery rainy roads – proper installation enhances handling safety and saves both hassle and money.

From a safety expert's perspective: The 'inside' marking indicates the inner side of the tire, which is one of the fundamentals to ensure driving safety. If installed incorrectly, the tread pattern of asymmetric tires cannot effectively drain water, increasing the risk of skidding on wet roads or tire blowouts. I have seen many accident cases caused by incorrect tire direction, leading to loss of vehicle control. Car owners must confirm this marking faces inward after tire replacement and consult professionals if necessary to ensure correctness. A simple check can prevent major troubles—road safety is no trivial matter; it starts with the details.

How Many Liters of Transmission Fluid Does a Car Need?

For manual transmission fluid change (gravity drain method), approximately 4 to 6 liters are required; when using a fluid exchange machine, about 9 to 12 liters are needed. Different vehicle models have varying replacement intervals. Below are the recommended transmission fluid replacement cycles: Manual Transmission: Manual transmission fluid is generally recommended to be replaced every three years or approximately 100,000 kilometers. Automatic Transmission: Automatic transmission fluid is typically advised to be replaced every two years or around 40,000 kilometers. Continuously Variable Transmission (CVT): CVT fluid is usually recommended for replacement every two years or about 60,000 kilometers. The methods for changing transmission fluid are as follows: Unscrew the drain plug at the bottom of the transmission to drain the old fluid before refilling. Directly remove the transmission oil pan for draining and refilling: This method provides a more thorough replacement than the previous one by removing deposits from the bottom of the oil pan. Using a circulation machine for automatic transmission fluid change: A smart circulation machine enables dynamic fluid exchange, filtering and cleaning sludge and impurities within the automatic transmission.

Is It Safe to Store Engine Oil in the Car?

It is safe to store engine oil in the car. Since engine oil is not classified as a hazardous material and is not flammable, it can be normally stored in the trunk without adhering to the regulations for transporting or storing hazardous materials. Engine oil, also known as motor lubricant, serves multiple functions for the engine, including lubrication and wear reduction, auxiliary cooling, sealing against leaks, rust and corrosion prevention, and shock absorption. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of the lubricant, determining its fundamental properties, while additives compensate for and enhance the shortcomings of the base oil, providing additional performance benefits. Additives are a crucial part of the lubricant. Based on the base oil classification, engine oils are typically divided into three categories: mineral oil, semi-synthetic oil, and full-synthetic oil. Among these, full-synthetic oil offers the best performance, maintaining a lubricating film at high temperatures and effectively reducing wear on engine components. It also provides excellent low-temperature protection, ensuring smooth engine starts in cold conditions. Its detergency and dispersancy effectively control sludge and varnish formation, keeping the engine internals clean. Additionally, it helps reduce fuel consumption and engine oil loss, offering good economic benefits. Different types of engine oils have varying oil change intervals: mineral oil typically requires replacement every 5,000 kilometers, semi-synthetic oil every 7,500-8,000 kilometers, and full-synthetic oil can last up to 10,000 kilometers.

What to do if you run a red light with a temporary license plate?

The penalties for running a red light with a temporary license plate are as follows: 1. Running a red light results in a fine of 200 yuan and 6 demerit points. 2. Failure to install the license plate as required (temporary license plates should be affixed both front and rear) may result in a fine of 200 yuan and 12 demerit points. 3. The paper motor vehicle license plate that permits temporary road use is also known as a temporary vehicle license plate. It refers to the temporary vehicle driving certificate issued by the public security vehicle management department for newly purchased vehicles before official registration. The validity period of a temporary license plate generally does not exceed thirty days. If it is a temporary license plate with a "sky blue background, black characters, and black borders," it is only for motor vehicles driving within the city limits; if it is a temporary license plate with a "brown-yellow background, black characters, and black borders," it is for motor vehicles driving across cities. The premise for deducting points with a temporary license plate is that the temporary license plate is obtained through official channels and linked to the owner's phone. If the temporary license plate does not correspond to the vehicle, running a red light cannot be recorded. The temporary license plate must be affixed as required; otherwise, the camera cannot record it. The red light intersection must have a camera that captures the moment of running the red light, or the driver must be stopped by traffic police for running the red light.

What is the boiling point of engine oil?

Typically, the boiling point of engine oil is around 150 degrees Celsius, but the exact boiling point varies by brand and requires actual testing to obtain an accurate value. In addition to the boiling point, other parameters of engine oil are as follows: Definition and significance of engine oil flash point: The lowest temperature at which an oil product can produce a flash when exposed to a flame under test conditions is called the flash point. It refers to the temperature at which the oil begins to flash when exposed to a flame during a test where the temperature is continuously increased. Depending on the testing method, the flash point of oil can be classified into open-cup and closed-cup flash points. The flash point of engine oil is an indicator of its volatility. The lighter the oil fraction, the higher its volatility, and the lower its flash point. Conversely, the heavier the oil fraction, the lower its volatility, and the higher its flash point. Additionally, the flash point is an indicator of the fire hazard of petroleum products. Definition and significance of engine oil pour point: The pour point of engine oil refers to the highest temperature at which the surface of the oil sample stops moving when cooled under specified test conditions. It is a conventional indicator used to measure the low-temperature fluidity of lubricating oils. A higher pour point indicates poorer low-temperature fluidity of the oil. Definition and significance of engine oil ash content: The solid residue left after burning an oil sample under specified conditions is called sulfate ash, expressed as a percentage. A higher number indicates that the engine oil may be more prone to sludge formation.

Is there a make-up test opportunity on the same day if I fail the first attempt in Subject 1?

Yes, there is a make-up test opportunity on the same day if you fail the first attempt in Subject 1. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," candidates are allowed to take the Subject 1 test twice on the same day. If the first attempt is unsuccessful, a free second attempt is permitted. However, if the second attempt also fails, the Subject 1 test will be terminated, and the candidate must wait for ten days before reapplying. Subject 1, also known as the theoretical test or driver's theory test, is part of the motor vehicle driver's license examination. The test covers driving theory basics, road safety laws and regulations, local ordinances, and related knowledge. It is conducted as a computer-based test with a time limit of 45 minutes. A passing score is 90 out of 100, with the test consisting of 100 questions, including single-choice and true/false questions, each worth 1 point. If a candidate answers 11 questions incorrectly, the system will automatically submit the test and end the session. Subject 1 test content includes: driver's license and motor vehicle management regulations; road traffic conditions and rules; traffic safety violations and penalties; traffic accident handling regulations; basic knowledge of motor vehicles; local ordinances; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Test-taking precautions for Subject 1: Candidates should dress appropriately (no slippers), avoid bringing electronic devices or bags into the examination hall, carry their ID cards, and queue to enter the waiting area. Observe the instructions and procedures displayed on the screen, and store personal belongings in lockers before entering the examination hall. Upon entering, verify identity at the assigned station and begin the test. Ensure the camera is properly aligned and adhere to test discipline. If the first attempt fails, a same-day make-up test is allowed. If the second attempt also fails, candidates must pay to reschedule. After completion, queue to collect and sign the score report; unsigned reports are considered invalid. There is no limit to the number of attempts for Subject 1, but Subjects 2 and 3 are limited to five attempts each. If all five attempts fail, the previously passed road driving skill test scores remain valid. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the examination on road traffic safety laws, regulations, and related knowledge. Subject 2 refers to the field driving skills test. Subject 3 is divided into two parts: road driving skills and safe and civilized driving knowledge. The safe and civilized driving knowledge test is conducted after Subject 3, commonly referred to as Subject 4, although the official term (as per the Ministry of Public Security's Order No. 123) does not include "Subject 4."
