4S shops can perform touch-up painting during maintenance. However, touch-up painting at a 4S shop is not free and incurs a charge. Generally, touch-up painting is calculated based on the entire panel where the scratch is located. But if the damage is minor and not very noticeable, the 4S shop might apply a small touch-up for free. Below are some methods for protecting your car's paint: 1. Waxing: Waxing can be done directly or after polishing. Direct waxing involves cleaning the car body and applying wax directly to the clear coat on the surface of the paint. Polishing and waxing, on the other hand, requires using a polishing machine to polish the paint surface before applying wax. This method can instantly make the car shine. 2. Glazing: Due to the composition of the glaze, it is not resistant to acid and alkali cleaning and can be easily damaged. It typically lasts only 1 to 3 months. Moreover, glazing can harm the car's paint, requiring reapplication every two to three months. 3. Crystal Coating: Crystal coating is a hard protective layer specifically designed for key areas of the car, such as the paint surface, seats, interior and exterior trim, glass, and tires. It comes in fast-drying and slow-drying types, mainly determined by its primary components. 4. Film Application: Car coating is a highly effective protective measure that can brighten the paint surface while also providing multiple benefits such as resistance to acids and alkalis, high temperature resistance, strong waterproofing, oxidation resistance, and UV protection.

Should the Car Cover Be Removed When It Rains?

After it rains, it is best not to remove the car cover. Wait until the weather clears up, and the cover will dry under the sun. Only after it is completely dry should you take it off and store it. If you remove it before it dries and leave it stored for a long time without drying, the car cover may develop mold and become more prone to damage. Additionally, the car's paint will not fade. Below are the main functions of a car cover: 1. Besides cleaning and sun protection, car covers also have excellent water-repellent properties, preventing damage from freezing in cold weather; effectively protecting against falling objects, fireworks, and other accidental factors that could harm the vehicle; and deterring theft of the vehicle and its accessories. 2. Spring: Protects against windblown sand, corrosive dust, pollen, tree sap, bird droppings, and damage from insects, ants, and animal claws. 3. Summer: Shields against UV rays, radiation, acid rain, and excessive sun exposure, preventing paint from fading, staining, or whitening, as well as keeping the car's interior leather and decorations from drying out. 4. Autumn: Guards against frost and icy dew. 5. Winter: Protects against rain and snow, ensuring the car's cooling system starts easily.

What Are the Causes of Excessive Engine Oil Consumption in Cars?

Reasons for excessive engine oil consumption: 1. Worn or damaged piston rings, misaligned or incorrectly installed piston rings. When piston rings wear out, their elasticity weakens, reducing the pressure on the cylinder walls and diminishing their oil-scraping function. Additionally, wear between the piston rings and ring grooves increases side and back clearances, leading to more oil leakage, especially if the oil ring is damaged, which can multiply the leakage. Furthermore, misaligned or incorrectly installed piston rings create a pathway for oil splashed onto the cylinder walls to enter the combustion chamber, significantly increasing oil consumption. 2. Excessive clearance between the piston and cylinder wall. If the fit between the piston and cylinder wall is too loose or the cylinder becomes tapered or oval-shaped, the piston rings, piston, and cylinder wall cannot seal properly. This allows splashed oil to enter the combustion chamber and burn, causing a sharp rise in oil consumption. 3. Use of low-viscosity oil. Low-viscosity oil is more prone to entering the combustion chamber and has a thinner oil film, making it easier to burn. Additionally, low-viscosity oil has a higher evaporation rate. 4. High engine speed. The higher the engine speed, the greater the centrifugal force on the crankshaft and connecting rods, which increases the amount of oil splashed onto the cylinder walls. As a result, the oil ring cannot scrape off the oil fast enough, leading to more oil entering the combustion chamber and burning.

Why does the car suddenly shake when idling?

Car idling shaking is caused by severe engine carbon deposits, ignition system failure, unstable oil pressure, and aging engine components. Severe engine carbon deposits, excessively dirty throttle, or excessive carbon deposits in the fuel injector are the most common causes of engine shaking. Here is a detailed explanation: 1. After a car has been driven for a period of time, a dirty throttle can cause the throttle to not close tightly or the idle stepper motor to get stuck, both of which can result in excessively high engine idle speed. Carbon deposits generated during engine operation can also cause vehicle shaking, especially when starting the vehicle. The engine may shake more than usual, and sometimes it may even fail to start on the first attempt. 2. Ignition system failure: Spark plugs, high-voltage wires, and ignition coils may experience poor ignition system performance after working for a certain period. 3. Unstable oil pressure: Abnormal fuel pump supply pressure or incorrect and poor performance of the intake pressure sensor can cause engine shaking. 4. Aging engine components: Turning on the electrical system when the car engine is idling will increase the engine load, causing the idle speed to drop. To compensate for the shaking caused by the drop in idle speed, the engine will automatically increase the speed slightly. If the shaking during idling does not decrease when the car's air conditioning compressor is running, it may be due to aging engine mounts, which need to be replaced promptly.

How to Permanently Disable Auto Start-Stop?

Auto start-stop cannot be permanently disabled, it can only be turned off each time. Generally, vehicles equipped with auto start-stop have this function enabled by default. To disable it, the owner can simply press the auto start-stop button, and the instrument panel will usually indicate that the system is turned off. If you want to use this function again, press the button to reactivate it. Auto start-stop refers to the engine automatically shutting off during temporary stops, such as waiting at a traffic light, and automatically restarting when the car begins to move. This is achieved by installing an enhanced motor with idle start-stop functionality in a traditional engine, allowing the engine to completely shut off when idle stop conditions are met.

What maintenance is required for a sedan at 20,000 kilometers?

Generally, the 20,000-kilometer maintenance for a car is considered a major service, typically the third maintenance session. Routine items include changing the engine oil, oil filter, air filter, cabin air filter, and spark plugs. Below is a detailed explanation: 1. Replacing the engine oil and oil filter is essential. Under the harsh conditions of high temperature and high pressure inside the engine, the shelf life of engine oil is significantly shortened, and its performance degrades considerably. Over time, it fails to protect the engine effectively. The oil filter prevents impurities from mixing with the oil, which can cause oxidation, leading to sludge and clogging the oil passages. Both the engine oil and oil filter should be replaced simultaneously. 2. The air filter's role is to block dust and particles that the engine might inhale 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. If it wasn't replaced during the 10,000-kilometer maintenance, it must be replaced at the 20,000-kilometer service. 3. 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 efficiency. If you notice a lack of engine power while driving, it's time for maintenance. The lifespan of spark plugs varies depending on the material used.

What is the handling method for failing the driving test 5 times?

The handling method for failing the driving test 5 times is: the results will be invalidated and the candidate must start over. In the driving test, the number of times for scheduling the road driving skills test for Subject 2 and Subject 3 cannot exceed five. If the candidate still fails the fifth scheduled test, the results of other subjects that have been passed will be invalidated, and the candidate must retake the Subject 1 test. The motor vehicle driving test is an examination to obtain a motor vehicle driving license. It adopts nationally unified test content and passing standards. The test is divided into three subjects and four tests: theoretical knowledge, field driving skills, road driving skills, and civilized driving-related knowledge. Different test items are specified according to different permitted driving models.
