Is It Normal for the Four Tires to Have Different Tire Pressures?

It is normal for the four tires to have slightly different tire pressures, as long as the differences are not significant. The details are as follows: 1. Factors Determining Tire Pressure: The tire pressure of a car should be determined based on the vehicle model, especially the weight distribution ratio of the vehicle, to set the tire pressure values for all four tires. 2. Family Cars: These are typically front-wheel drive. The engine and transmission are located at the front, so the vehicle's center of gravity is concentrated in the front. Generally, the recommended tire pressure is 2.5-2.7 for the two front tires and 2.3-2.5 for the two rear tires. The front tires not only bear the weight of the engine and transmission but are also responsible for steering, so they require slightly higher tire pressure than the rear tires. 3. Luxury Cars: Luxury cars usually maintain a 1:1 weight distribution between the front and rear, meaning the vehicle's center of gravity is in the middle of the body. For such cars, the front and rear tires have the same tire pressure.

What Type of Engine Oil Should a Turbocharged Car Use?

For vehicles equipped with turbocharged engines, it is recommended to use 5w40 or 0w40 engine oil, and it should be fully synthetic oil. This type of oil provides better lubrication and has a longer service life. Here are some relevant details: 1. Engine oil is referred to as the lifeblood of the engine, and it plays a crucial role in engine operation. When the engine is running, the oil forms a protective film on the surfaces of various components inside the engine, preventing direct contact and friction between them. This helps reduce engine wear. 2. Turbocharged engines have a turbocharger, which also requires oil for lubrication and cooling during operation. The turbocharger can reach speeds of up to several hundred thousand revolutions per minute, and due to these high speeds, the requirements for oil quality are very stringent. 3. The pressure and temperature inside the cylinders of a turbocharged engine are also very high during operation, so this type of engine demands even higher-quality oil. If oil with too low viscosity is used, it may fail to form a stable protective film on the engine components, which can accelerate engine wear.

Is the Volkswagen Jetta VS5 a joint venture car?

Jetta VS5 is a joint venture car. Here is the relevant content: Introduction to Jetta VS5: Jetta VS5 is a joint venture car. The Jetta brand still belongs to the Volkswagen Group and is a low-end brand under FAW-Volkswagen Automotive Co., Ltd., a joint venture of the German Volkswagen Group in China. The Jetta VS5 is the first SUV model of the Jetta brand, built on Volkswagen's most advanced MQB A1 platform and equipped with the same engine used in Volkswagen and Audi models. Definition of a Joint Venture Car: A joint venture car is a product of a project jointly established by Chinese and foreign investors. The Chinese side contributes by providing land and factory usage rights, as well as capital, while the foreign investors provide the brand, technology, capital, and talent. Joint venture cars are assembled domestically with technology, talent, and brands provided by foreign parties, but the core technology remains controlled by the foreign side.

How to Use ETC on Free Highways?

For free highway ETC users: Enter via ETC lane and exit via ETC lane - no charge; Enter via manual lane and exit via manual lane - no charge; Enter via manual lane and exit via ETC lane - no entry information, barrier won't lift at exit; Enter via ETC lane and exit via manual lane - passable without charge. ETC usage precautions: The ETC transaction sensing range is 8 meters. When following another vehicle, maintain at least 10 meters distance to prevent accidental payment for the vehicle ahead in case its ETC device malfunctions or is absent. The ETC lane recognition speed limit is 20km/h. Excessive speed will prevent vehicle device information from being read, resulting in failed payment. Unauthorized OBU device movement, detached or loose ETC electronic tags will cause deactivation. These can be inspected at the bank where the ETC card was issued or at highway service centers. Non-deliberate detachment only requires reactivation.

How to Determine if an Engine Has Cylinder Scoring?

Here are the methods to determine if a car has cylinder scoring: 1. When cylinder scoring occurs, the car will experience jerking and the engine will produce significant abnormal noises, with reduced RPM and noticeably decreased power. 2. Cylinder scoring is caused by severe surface damage due to the mutual movement of the piston and cylinder, mostly resulting from localized destruction of the lubricating oil film on the moving parts. Here are some relevant details: 1. The cooling efficiency of the engine's cooling system, the quantity and quality of engine oil, and the working performance of the supply system are all critical factors that can cause fatal damage to the engine. 2. The causes of cylinder scoring include: (1) The clearance between the piston and cylinder is too small; (2) Insufficient lubrication between the piston and cylinder or incorrect oil selection; (3) Failure of the engine cooling system; (4) Low hardness or poor quality of the cylinder itself.

What Causes the Fuel Gauge Not to Display on the Dashboard?

Dashboard not displaying fuel level is caused by a malfunctioning fuel level sensor. Below are specific details about the car fuel tank: Marked capacity is the safe volume: Most fuel tanks are marked with a safe capacity, which is generally about 10% less than the actual capacity. During design, considering the thermal expansion and contraction characteristics of fuel, to ensure driving safety, a certain space must be left in the tank after filling to the rated volume to prevent excessive internal pressure. Overfilling can damage the carbon canister, while underfilling leaves too much empty space, causing fuel to evaporate and be lost as vapor. Fuel gauge cannot accurately reflect remaining fuel: It is not possible to accurately determine the remaining fuel solely based on the dashboard fuel gauge, as it provides only a qualitative indication rather than a quantitative measurement. The relationship between fuel refill amount and mileage cannot be used to judge either, because road conditions, speed, traffic congestion, air conditioning usage, vehicle load, fuel leakage, and fuel quality all directly affect fuel consumption.
