What is the difference between buying a car from a car dealership and a 4S store?

Differences between buying a car from a car dealership and a 4S store: Different sources of vehicles: Car dealerships have multiple channels for sourcing vehicles, while 4S stores are usually directly authorized by manufacturers, with vehicles supplied directly from the manufacturer, ensuring higher quality. However, car dealerships offer a wider variety of vehicles, typically sourced from comprehensive brand merchants or secondary dealers who retail from 4S stores, providing better options when purchasing a car. Different after-sales services: Cars bought from 4S stores come with more reliable after-sales services. Even after the warranty period expires, the manufacturer will still honor the warranty. However, this may not be the case for cars bought from secondary dealers or car factories, so 4S stores perform better in terms of after-sales services. If a car bought from a dealership is privately modified or repaired, it may affect the after-sales service even during the warranty period. Higher prices at 4S stores: Many consumers are aware that the more professional the service, the higher the price tends to be. However, this also ensures a certain level of quality, and the time to pick up the car is usually shorter when buying from a 4S store.

How Long Does an Auto Start-Stop Battery Last?

For vehicles equipped with auto start-stop functionality, the battery lifespan typically ranges from 4 to 6 years. Conventional car batteries use lead-acid technology with a cycle life of approximately 200 to 500 charges, lasting about 2 to 4 years. Key considerations: Standard batteries operate while charging, essentially performing shallow charge-discharge cycles, which extends their service life. AGM (Absorbent Glass Mat) batteries are commonly installed in start-stop enabled vehicles. These advanced batteries, along with EFP (Enhanced Flooded Plate) maintenance-free lead-acid batteries, feature more sophisticated technology compared to traditional lead-acid batteries. They better withstand the demands of frequent engine restarts and increasing electrical loads in modern vehicles. To improve fuel efficiency, an increasing number of new vehicles incorporate auto start-stop systems. These systems employ a dedicated start-stop battery that exclusively powers the start-stop function. Most engine wear occurs during cold starts with dry friction, whereas hot starts during normal operation (with proper lubrication) cause minimal wear. Modern start-stop systems incorporate multiple protective measures - they automatically disable during low coolant/oil temperatures or when climate control systems are active - to safeguard engine components.

What should be paid attention to when installing spark plugs?

Precautions for installing and replacing spark plugs: When removing the high-voltage distributor wires, mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. During removal, check for external debris such as leaves or dust, and ensure they are thoroughly cleaned. Methods to determine if a spark plug is damaged: Remove the spark plug and observe its condition based on the following appearance colors. A normal spark plug has an insulator skirt and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a reddish-brown insulator skirt, with an electrode gap between 0.8-0.9mm and no signs of electrode burning. If the spark plug is contaminated with oil or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged, with signs such as blistering at the top, black streaks, cracks, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plug with a new one. Additionally, if the spark plug appears black as if smoked, it indicates the wrong heat range was selected or the mixture is too rich, with oil creeping up.

What is the Chinese name for DS cars?

DS is called Di Ai Shi in Chinese, a French car brand. It generally refers to the premium brand under Peugeot Citroën. DS is highly favored by French political figures and is known as the "Presidential Car". From Charles de Gaulle to François Hollande, DS has been the preferred choice for French presidents. The history of the Di Ai Shi brand: In 1955, DS made its debut at the Paris Motor Show, causing a sensation with its design and technological innovations, sparking a revolution in the automotive industry and holding a significant place in the history of automobile development. In 1957, DS launched a more affordable version—the DS-ID. Despite its excellence, the price still dampened the purchasing inclination of the general public. In 1958, DS introduced the station wagon version. This DS station wagon had completely different names in various markets. In France, it was called Break, in the UK Safari, in the US Wagon, and in Australia, Safari or Station-Wagon was used as the product name. The DS-Break featured a steel roof (the DS roof material was fiberglass) to support the standard roof rack. In 2011, Changan Peugeot Citroën Automobile Co., Ltd. was established. In 2012, the DS brand officially entered China with its products, serving as the new generation luxury car brand under the Peugeot Citroën Automobile Group, dedicated to providing consumers with a comfortable driving experience.

How far can you drive after the fuel gauge light comes on?

When the car's fuel gauge light comes on, you can still drive approximately 30 to 50 kilometers. Here are some precautions regarding the use of the fuel gauge: Pointer indication deviation: When the fuel pump is operating, a negative pressure is created inside the fuel tank, reducing the tank's volume and causing the fuel level to appear higher. Additionally, the thermal expansion effect of gasoline due to temperature can naturally display a higher reading. When the temperature drops or the fuel tank is opened, the pressure is released, and the fuel level decreases accordingly. Therefore, such display deviations are normal. However, the deviation generally does not exceed the width of one pointer. Do not continue driving after the indicator light comes on: When the indicator light comes on, it indicates that the fuel level is too low. Continuing to drive at this point can be harmful because the fuel pump, located inside the fuel tank, generates a significant amount of heat during operation. The fuel acts as its coolant, ensuring the fuel pump functions properly by continuously cooling it. Without the cooling effect of the fuel, prolonged operation of the fuel pump will inevitably lead to burnout. Refuel promptly after the indicator light comes on: It is essential to refuel promptly after the indicator light comes on because the fuel pump relies on gasoline for both cooling and lubrication. Insufficient fuel levels can impair the fuel pump's normal operation and reduce its service life.

Can Alcohol Be Used to Wipe Car Paint?

Alcohol can be used to wipe car paint, as it has poor dissolving power. However, it may affect the gloss of the paint, so it should be rinsed off with water immediately after use. Here is some information about alcohol: 1. Ethanol (C2H6O), an organic compound with the structural formula CH3CH2OH or C2H5OH, commonly known as alcohol, is the most common monohydric alcohol. 2. At room temperature and pressure, ethanol is a flammable, volatile, colorless, and transparent liquid with low toxicity. The pure liquid is not drinkable directly; it has a distinctive aroma and slight irritation, with a mildly sweet taste accompanied by a spicy sensation. It is flammable, and its vapor can form explosive mixtures with air. It is miscible with water in any ratio and can also mix with chloroform, ether, methanol, acetone, and most other organic solvents. Its relative density (d15.56) is 0.816. 3. Ethanol has a wide range of applications, including the production of acetic acid, beverages, fragrances, dyes, and fuels. In the medical field, ethanol with a volume fraction of 70%~75% is commonly used as a disinfectant. It also has extensive uses in defense chemicals, healthcare, the food industry, and industrial and agricultural production.
