How Much 92 Gasoline Should Remain Before Switching to 95?

To extend the engine's service life, it is recommended to switch to 95 gasoline after the 92 gasoline is completely used up. The relevant details about 92 and 95 gasoline are as follows: 1. Short-term mixing is acceptable: Theoretically, mixing different grades of gasoline for a short period will not cause significant harm to the car. However, since the stability of 92 and 95 gasoline differs, extensive mixing may lead to stability issues. Long-term mixing of different gasoline grades can affect the lifespan of the car's ignition system, fuel injectors, and spark plugs. 95 gasoline produces less knocking than 92 gasoline, making the engine quieter. However, since the compression ratio of engines designed for 92 gasoline is not high enough to fully utilize the characteristics of 95 gasoline, incomplete compression and combustion may occur, leading to sluggish acceleration during driving. 2. Which one is suitable: Some vehicles only require 92 gasoline, but their engines were calibrated during the development phase for 95 or higher-grade gasoline. Therefore, when using 95 gasoline, the characteristics of 95 gasoline can be fully utilized to unlock its potential.

What are the effects of not changing transmission fluid?

Not changing the transmission fluid can have the following effects: 1. It causes the transmission fluid to become thicker, reducing oil pressure and hindering internal heat dissipation, leading to excessively high oil temperatures. This shortens the lifespan of both the transmission and the drivetrain components. 2. Failure to change the transmission fluid may result in weak acceleration when starting the vehicle, and frequent slipping may occur during driving. 3. Prolonged neglect of transmission fluid changes can cause the fluid to degrade and evaporate under high-speed and high-temperature conditions, accelerating component wear and damaging internal transmission parts. Below are the functions of transmission fluid: (1) The primary role of transmission fluid is to keep the shifting system clean and to lubricate the drivetrain, thereby extending its lifespan. (2) Transmission fluid serves to clean, lubricate, cool, and seal the transmission. Due to the specific operating conditions inside the transmission, the quality of the fluid has a limited shelf life. Over time, the fluid's performance deteriorates, accumulating more impurities, which accelerates wear on transmission components, leading to earlier failures or higher failure rates.

What Maintenance is Required for a Car at 10,000 Kilometers?

Car maintenance at 10,000 kilometers includes the following: 1. Oil and Oil Filter Replacement: The engine oil needs to be changed at 10,000 kilometers. Since oil lubricates the engine during operation, its performance degrades over time, potentially leading to failure. Timely replacement during maintenance prevents abnormal engine wear. 2. Vehicle Inspection: After driving 10,000 kilometers, inspect the engine, transmission, air conditioning system, steering system, braking system, suspension, body, tires, etc., to ensure optimal performance. 3. Clean or Replace Air and Cabin Filters: It's recommended to clean the air and cabin filters after 10,000 kilometers. If driving conditions are harsh, replacing them at this interval ensures better protection. These parts are inexpensive and can be replaced by the owner, but professional assistance is advisable if unsure. 4. Check Various Vehicle Fluids: After 10,000 kilometers, inspect coolant, brake fluid, tire pressure, etc. Abnormal fluid levels can cause excessive wear and affect performance during operation.

What to Do When the Tire Pressure Monitoring Light Comes On?

The tire pressure monitoring system warning light coming on indicates that you should pull over to check the situation. If the issue is minor, you can resolve it yourself. For more serious problems, drive slowly to a 4S shop. Here are some tire-related precautions: 1. Inflation: In winter, car owners should appropriately increase tire inflation pressure to reduce tire wear and consumption. However, at the same time, if the road is icy and slippery, excessive tire inflation pressure can affect the tire's grip. 2. Potholes: When a tire rolls over a pothole, it gets squeezed. The larger the pothole and the higher the speed, the greater the squeezing force on the tire, which can lead to bulging. 3. Temperature: When measuring tire pressure in winter, it should be done after the car has been driven for a while and the tires have cooled down, preferably at room temperature.

How to Pull Out a Dent in the Side Skirt?

Dents in the side skirt can be pulled out using a metalworking machine. The process involves pulling, shaping, sanding, applying putty, smoothing, spraying texture coating, and painting. The key factors are the location and severity of the dent. Minor dents can be fixed by purchasing spray paint and doing it yourself. Here are the details: 1. For severe dents in the side skirt, it is recommended to visit a professional auto repair shop or 4S store for the best treatment. Try to repair it from the inside as much as possible and avoid directly cutting the side skirt. 2. Simply put, metalworking involves metal correction - applying putty - painting - surface treatment. In theory, it does not harm the car, as the areas worked on are usually just some covering parts. However, it still has an impact on the metalworked areas. After all, whether it's steel or iron, once the structure is deformed and repaired, its strength will not be the same as before.
