Why is 0W20 more expensive than 0W40?

0W-20 engine oil provides lubrication at low temperatures of minus thirty degrees Celsius and has lower viscosity. Low-viscosity oil requires higher costs to achieve the same performance, making it more expensive. Here is some relevant information about 0W20: 1. Introduction: 0W-20: The "W" stands for "winter," indicating it is suitable for winter use. The number before the "W" (0) represents the viscosity at low temperatures. The smaller the number, the better the fluidity at low temperatures and the stronger the cold resistance. The "20" indicates the viscosity at 100°C. The larger the number, the higher the viscosity and the better the high-temperature resistance. 2. Disadvantages: If the oil viscosity is too low, the oil cannot form a stable oil film on the surfaces of various engine components, which will increase engine wear. If the viscosity is too high, it will increase the resistance during engine operation, leading to reduced engine power and increased fuel consumption.

Where does the outside air circulation in a car come from?

Simply put, the outside air circulation system connects the air intake to openings in the car body, drawing air from outside, while the exhaust has a vent valve. Here are some tips for using car air conditioning: 1. Ventilate before turning on: After the car has been parked in the sun for a long time, open all four doors and the sunroof to allow air to circulate for 3 minutes. This quickly lowers the interior temperature, making the air conditioning more effective when turned on. 2. Use the recirculation mode wisely: The recirculation mode blocks hot outside air, creating a sealed space inside the car. This allows the interior air to circulate quickly under the air conditioning, achieving rapid cooling. Once the interior temperature has dropped, it is recommended to switch to outside air circulation every 30 minutes to refresh the air inside the car, then switch back to recirculation after 5 minutes. 3. Turn off the air conditioning in time: Turn off the air conditioning 5 minutes before parking to protect the engine and save fuel.

Why is the car's cold air not cooling effectively?

The reasons why the car's cold air is not cooling effectively are as follows: 1. Lack of refrigerant: This leads to insufficient refrigerant in the air conditioning system's pipelines, requiring a refill. 2. Long-term lack of maintenance: Dirty or clogged air filters and condensers can result in poor cooling performance, which can be resolved by cleaning or replacing the air filter. Daily usage tips for car air conditioning: 1. Correct air vent direction: If the air vent direction is incorrect, it can affect the cooling efficiency. When using the air conditioner for cooling, the vents should face upward, while in winter for heating, they should face downward. 2. Avoid prolonged use of internal circulation: Internal circulation in car air conditioning means air is recirculated within the closed cabin space, leading to a gradual decrease in oxygen levels. Continuous internal circulation can deteriorate air quality inside the car. The correct approach is to alternate between internal and external circulation periodically to allow fresh air into the cabin. 3. Limit prolonged use of the air conditioner: Extended use of the air conditioner can cause wear and tear on the cooling system. If the desired temperature is reached, it's advisable to turn off the air conditioner and turn it back on after a while.

Are 4S Store Inspections Free?

4S stores offer free inspection services, which generally include checking all vehicle lights, the braking system, tires, chassis, and electronic equipment. Below is relevant information about vehicle inspections: 1. Vehicle Inspection: After a vehicle has been driven for a period, various components undergo wear and tear. It is necessary to conduct a comprehensive inspection of the engine, chassis, electrical systems, and all vehicle fluids to identify potential faults early and ensure driving safety. 4S stores employ professionally trained technicians, specialized computer diagnostic tools, professional equipment, and fluid analyzers to perform more professional inspections. 2. Routine Inspection and Maintenance: To ensure the safe and reliable operation of a vehicle and maintain it in good technical condition, complying with the technical standards for safe vehicle operation, in addition to regular maintenance and repairs, preventive routine inspections and maintenance should also be conducted.

What is the Volkswagen throttle data stream channel number?

060 is the matching channel number for the electronic throttle of Volkswagen gasoline vehicles. As for the data stream, no channel number is required. Here is the relevant introduction: 1. Throttle Introduction: The throttle is a controllable valve that regulates the air entering the engine. There are two types: the traditional cable type and the electronic throttle. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to perform work. Connected to the air filter above and the engine block below, it is known as the throat of the car engine. The flexibility of the car's acceleration is closely related to the cleanliness of the throttle. 2. Traditional Throttle: The traditional engine throttle control mechanism operates via a cable or rod, with one end connected to the accelerator pedal and the other to the throttle linkage plate. The electronic throttle primarily uses a throttle position sensor to control the throttle opening angle based on the engine's required energy, thereby regulating the amount of air intake.

How to Determine When to Replace Motorcycle Tires?

Here are the signs indicating that motorcycle tires need replacement: 1. Insufficient Tread Depth: Every motorcycle tire has a "tread wear indicator" △ mark near the tread on both sides of the tire shoulder. Extending the lines from these marks to the center of the tread will reveal a raised bump approximately 1.0 mm high in the groove. If, when viewed directly (not from the side), the tread height is nearly level with this bump, it indicates that the wear has reached the limit of 0.8 mm, and it's time to replace the tire. Overly worn tires with insufficient tread depth can affect water drainage and increase the risk of slipping. 2. Prolonged Usage: Even if the tread wear hasn't reached the indicator, tires that have been in use for three years often start to harden, lose elasticity, and develop fine cracks due to environmental factors like temperature changes and UV exposure. In such cases, significant temperature fluctuations or excessive tire pressure can easily lead to a blowout while riding. 3. Puncture by Foreign Objects: If the tire is damaged by nails or sharp objects during riding, the safest course of action is to replace the tire. Although patching is an option, there's still a high probability of air leakage or a blowout while riding due to the compromised structure of the tire.
