What Type of Engine Oil Should Be Used for the First Car Maintenance?

For naturally aspirated engine models, synthetic or full synthetic engine oil is recommended, while turbocharged engine models should use full synthetic engine oil. The first maintenance oil is usually provided free of charge by the 4S shop. When most new cars go to the 4S shop for their first maintenance, the oil that will be replaced for free is usually mineral oil. If you want to use synthetic oil, you must pay an additional fee. Below are specific details about engine oil: 1. Engine oil can be divided into three types based on its chemical composition: full synthetic, synthetic, and mineral. 2. In addition to the type of engine oil, pay attention to the oil model. Engine oil models usually follow two standards—SAE and API. SAE indicates the oil viscosity specification, while API represents the oil quality grade.

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.
