Differences between the BMW 3 Series and the BMW 5 Series: 1. Different body dimensions: The BMW 3 Series measures 4650mm in length, 1811mm in width, and 1454mm in height; the BMW 5 Series measures 5087mm in length, 1868mm in width, and 1500mm in height. 2. Different powertrains: The BMW 3 Series only offers a 2.0-liter turbocharged engine option; the BMW 5 Series additionally provides 2.0-liter and 3.0-liter turbocharged engine options. In terms of exterior design, the BMW 3 Series adopts the design style of the overseas version of the new 3 Series, featuring sharp LED headlights connected to enlarged glossy black kidney grilles, complemented by front air intakes and three-dimensional lines. The BMW 5 Series showcases a new aesthetic design, interpreting a dynamic stance with its one-piece large-sized kidney grille, exuding a more imposing presence.

As a BMW owner, the most noticeable difference after switching from a 3 Series to a 5 Series after five years is the space gap. In the 3 Series, a 1.8-meter-tall friend would almost touch the roof in the back seat, and the trunk could barely fit two large suitcases; the 5 Series offers enough legroom to cross your legs and easily accommodates all the camping gear for a weekend family trip. The chassis tuning is even more distinct: the 3 Series feels bumpy over speed bumps but is rock-solid in high-speed corners; the 5 Series glides like driving on cotton, with ultra-smooth vibration absorption but noticeable body roll in turns. In terms of fuel consumption, the 3 Series is quite friendly at 8L/100km in city driving, while the 5 Series starts at 10L/100km under the same conditions. My advice: young drivers should go for the 3 Series for fun and easy parking, while families should opt for the 5 Series to enjoy the spacious comfort.

What Does Vehicle Scratch Insurance Cover?

Here is a detailed introduction to the coverage of scratch insurance: 1. Coverage Scope: Scratch insurance can cover damage to the car's paint caused by sharp objects. However, car owners should note that losses resulting from collisions with other objects, such as vehicle collisions or scraping against fixed objects, are not covered by scratch insurance but fall under the category of vehicle damage insurance. 2. Insurance Liability for Scratches: The insurance liability of scratch insurance is for malicious acts by others that cause artificial scratches on the insured vehicle's body. Losses caused by intentional actions of the insured and their family members, or the driver and their family members, are excluded from coverage.

Do Cars Need to Warm Up in Summer?

Do Cars Need to Warm Up in Summer? Here are the specific details about car warm-up: 1. Warm-up time: Cars need to warm up in all seasons, requiring at least 15 seconds before slowly moving out. 2. Other operations: Besides warming up, you should also wait until the coolant temperature gauge reaches the normal range before turning on the car's air conditioning. Here is additional information about car warm-up: 1. Long-term unused cars: The upper part of the engine lacks oil and lubrication when starting. After 30 seconds of operation, the oil pump will deliver oil to the parts of the engine that need lubrication the most. 2. Engine not reaching operating temperature: Before the engine reaches its operating temperature, the fuel system cannot effectively vaporize gasoline completely due to low temperature.

Can 0W-40 engine oil be used in summer?

0W40 engine oil has a viscosity rating of 40 after the W, which refers to the oil viscosity at 100°C. This indicates that 0W40 oil has higher viscosity at high temperatures, providing excellent protection and making it suitable for summer use. Advantages and disadvantages of Mobil 0W-40W engine oil: 1. Contains active detergents to prevent carbon deposits and sludge buildup, keeping the engine clean and extending its lifespan; 2. Outstanding thermal and oxidation stability, delaying oil aging and extending oil change intervals; 3. Low oil consumption, reducing hydrocarbon pollution; 4. Good friction characteristics, leading to higher fuel efficiency; 5. Excellent low-temperature performance, enabling quick cold starts and rapid protection.

How to Check for Air Leakage in Car Air Conditioning?

Air leakage in car air conditioning generally falls into two scenarios: undetectable leakage points during high-pressure checks and issues that arise during the refrigeration operation. The main methods to address these problems are as follows: 1. Soap Water Leak Detection. Fill the system with nitrogen at 10-20 kg/cm² pressure, then apply soap water to various parts of the system. Bubbles will appear at the leakage points. 2. Nitrogen Water Leak Detection. Fill the system with nitrogen at 10-20 kg/cm² pressure and immerse the system in water. Bubbles will indicate the leakage points. 3. Halogen Lamp Leak Detection. Light the leak detection lamp and hold the air tube of the halogen lamp. When the tube opening is near a system leakage point, the flame color will turn purple-blue, indicating a significant leak. 4. Gas Differential Pressure Leak Detection. Utilize the pressure difference between the inside and outside of the system, amplify the pressure difference through a sensor, and express the leak detection results digitally, through sound, or via electronic signals.

Where to Install ETC on the Windshield?

The ETC installation position for passenger cars is generally on the upper middle part of the front windshield, while for large vehicles such as trucks and buses, it is installed on the lower middle part. The appropriate installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with factory-installed or aftermarket explosion-proof film, which may affect the signal transmission of the microwave communication link, the ETC should be installed on the microwave sunroof strip. Here are the precautions for installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have windshields with a large rearward tilt angle, which reduces the driver's field of vision. If this is not considered when installing the ETC, it will increase the driver's blind spot. Installing it behind the rearview mirror on the right side can avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and positions that may block the solar panel. Do not remove it arbitrarily once installed: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After the electronic tag is installed, the windshield will press the anti-removal lever in. If the tag is removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to visit an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. Notes for using ETC: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic sensing and paying for the wrong vehicle. The ETC lane recognition speed is 20 kilometers per hour. If the vehicle speed is too fast, the system may fail to read the vehicle device information, resulting in a failed transaction. When using a debit card to bind the ETC, insufficient balance will also cause the transaction to fail.

What to Do When the Car Fuel Tank is Full?

If driving in the city for a long time, it is best not to fill up the fuel tank, as a full tank can increase fuel consumption. The effects of filling up the fuel tank are as follows: 1. First refueling for a new car: It is best not to fill it up completely, as overfilling may cause the fuel gauge and sensor to malfunction, leading to inaccurate fuel gauge readings. Try not to overfill when refueling. 2. Harm to the carbon canister: The gasoline vehicle fuel vapor adsorption and desorption device, commonly known as the carbon canister, is a device that reduces the emission of gasoline vapors from the car fuel tank. If the tank is overfilled, there is no space at the top of the gasoline tank, leaving no place for the gasoline vapors to escape. As a result, liquid gasoline instead of gasoline vapors enters the carbon canister, causing harm to it. Since gasoline contains various harmful substances, long-term exposure to gasoline vapors can be harmful to health and may even lead to cancer.
