Is It Harmful to Wash a Car Once a Month?

Washing a car once a month is not harmful. The need for washing is not determined by time but by how dirty the car is. The primary purpose of washing is to protect the paint, with aesthetics being secondary. Disadvantages of frequent car washing: It accelerates paint oxidation. During washing, many cleaners use cloths containing sand and dust to wipe the car's surface, leaving behind fine scratches and significant wear on the paint. Many car washes use low-quality detergents containing high levels of alkaline substances. Washing too frequently can cause white paint to yellow, which is detrimental to car maintenance. Hazards of not washing the car for a long time: The main issue is excessive dirt on the paint surface. In southern regions, frequent rain exposes the paint to acid rain, leading to yellowing and peeling. In northern regions, although rain is less frequent, the air is very dry, and large amounts of dust settling on the car can scratch the paint. Additionally, license plates may become obscured. Thick mud covering the license plate can make it unreadable, leading police to mistakenly assume intentional concealment and impose fines. The paint surface loses its protective film, making it more susceptible to damage. Furthermore, prolonged neglect can cause sealing strips to deteriorate, reducing their effectiveness. Car washing precautions: During continuous rainy days, simply rinsing off the mud with water is sufficient. There's no need to use detergent every time; a thorough wash can be done after the rain stops. During continuous sunny days, if the car is only dusty and not wet, a dust cloth can be used to clean the surface, followed by a damp cloth for the windshield and mirrors. A full wash isn't necessary.

Are all cars sold now China 6 compliant?

Not all cars sold now are China 6 compliant, as China 5 vehicles are still being sold in many regions. Here is an introduction to China 6 related knowledge: 1. Significance: Established to prevent environmental pollution from exhaust emissions of compression-ignition and gas-fueled spark-ignition engine vehicles, protect the ecological environment, and safeguard human health. 2. Issuing authority: On December 23, 2016, the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine issued the 'Limits and Measurement Methods for Emissions from Light-duty Vehicles (China 6)', which has been implemented since July 1, 2020.

Can the car still be driven if the water temperature exceeds 90 degrees?

It cannot be driven. The normal operating temperature of a car's water temperature should be above 70 and below 85 degrees. Exceeding 90 degrees means the car is in a dangerous state and should not be driven. Otherwise, if the temperature is too high, it can easily lead to overheating, causing the engine cylinder gasket to burst, and in severe cases, deformation of the cylinder head and block. Below are specific details about car water temperature: Main function: The car water temperature reflects the working condition of the cooling system. The engine must operate at a reasonably high temperature for optimal performance. At suitable temperatures, fuel can burn more efficiently and reduce emissions. Reasons for excessive temperature: The main causes of an engine running too hot include insufficient coolant, a faulty cooling fan, a malfunctioning water pump, a faulty thermostat, or poor radiator cooling. Symptoms of overheating: When the car's water temperature is too high, the dashboard may display a high water temperature or engine overheating warning. The engine cooling fan may rotate at high speed with loud noise. Engine knocking may occur. In severe cases, it may lead to engine bearing failure, making the engine unable to start.

Can You Continue Driving with Engine Shaking?

Theoretically, you can continue driving, but excessive carbon buildup can affect the car's power and increase fuel consumption. It is recommended to address the issue as soon as possible. Below is an analysis of the possible causes of engine shaking: 1. Severe Engine Carbon Buildup: Shaking caused by severe carbon buildup is most commonly due to dirty fuel injectors or excessive carbon deposits in the throttle. 2. Ignition System Issues: Check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or faulty spark plugs can also cause this issue. 3. Unstable Oil Pressure: If the fuel pump's supply pressure is abnormal or there are errors in the intake pressure sensor, it can lead to engine shaking.

Is it necessary to repair scratched rims?

It is necessary to repair scratched rims. Here is some relevant knowledge about rims: 1. Definition: Automotive rims refer to the components used to bear the rigid rotational inertia between the car and the tires, also known as wheel rims or steel rings. 2. Function: The main function is to influence the size of the braking system and the selection of tire specifications. Larger rims can accommodate bigger braking systems, and wider rims can use higher-performance wide tires. 3. Composition: A complete rim unit includes automotive bearings, also known as flanges, which work with the tires to support the wheels.

What are the reasons for stopping midway during Subject 2 of the driving test?

Reasons for stopping midway during Subject 2 of the driving test: 1. Poor clutch control: Inadequate mastery of the clutch, causing the vehicle speed to fluctuate suddenly or stop abruptly. The pressure applied to the clutch must be well-controlled. If the speed is too fast, press the clutch slightly; if the speed is too slow, release the clutch slightly. Always adjust it bit by bit, avoiding releasing it completely at once, as this can easily cause the engine to stall. Similarly, pressing it all the way down can lead to the vehicle stopping. 2. Uneven driving surface: The test area cannot be perfectly level; there will always be small bumps, slight depressions, or gentle slopes. Since vehicles are highly sensitive, even these minor imperfections in the terrain can cause the car to stop briefly. 3. High resistance when turning the steering wheel: When turning the steering wheel to its maximum angle, the slant of the front wheels creates significant resistance, causing the vehicle to stop momentarily.
