What kind of oil does the Geely Vision X6 use?

Why does the Mercedes-Benz 272 engine make abnormal noises when hot?

Mercedes-Benz 272 engine makes abnormal noises when hot for the following reasons: 1. Cold start noise. The oil pump has not yet fully built up oil pressure during cold start, resulting in insufficient lubrication for various components. Normally, the abnormal noise will disappear after the engine runs for a while. 2. Aging or loosening of engine mounts. The function of engine mounts is to reduce vibration and cushion the engine's operation, as well as to fix the engine. Once these mounts age or loosen, the engine will vibrate, and in severe cases, abnormal noises will occur. Simply replace with new engine mounts. 3. Overly rich air-fuel mixture. When the engine's air-fuel mixture is too rich, acceleration becomes difficult after starting, the engine runs unevenly, the exhaust pipe emits black smoke, and the engine is accompanied by a rattling noise, sometimes backfiring; engine power decreases, fuel consumption increases, which is related to carbon deposits, clogged filters, etc.

What is the Difference Between Winter and Summer Engine Oil?

Viscosity differs, with winter engine oil having lower viscosity and summer engine oil having higher viscosity. Below is relevant information: 1. Winter vs. Summer Comparison: Winter temperatures are low, and using oil with excessively high viscosity can lead to insufficient fluidity, increasing engine wear and resistance. Summer temperatures are high, and using oil with excessively low viscosity can result in inadequate lubrication. 2. Introduction to Viscosity: The effectiveness of engine oil relies on an important characteristic—viscosity. The oil must possess viscosity properties to provide a protective film for various engine components. Generally, viscosity refers to the physical property of the oil (while the viscosity index is a physicochemical indicator of the base oil), originally meaning the ease with which a fluid or semi-fluid flows, commonly referred to as "thick" or "thin."

Can Alipay be used to buy a car?

Alipay can be used to pay for a car purchase, but it depends on the regulations of the 4S store. However, Alipay may have a limit, such as a single transaction not exceeding 50,000 yuan. For merchants, Alipay payment reduces the steps of counting cash, which can improve efficiency and increase user satisfaction. Whether a car purchase can be made through Alipay transfer depends on whether the merchant supports Alipay transfer. There are three scenarios for car purchase: 1. Full payment: Naked car price + purchase tax + registration fee + insurance fee = total cost of the car. 2. Traditional mortgage: Naked car price + purchase tax + registration fee + insurance fee + loan interest + mortgage handling fee = total cost of the car. 3. Manufacturer subsidized installment: Naked car price + purchase tax + registration fee + insurance fee + installment handling fee = total cost of the car.

How to Identify Tire Wear Indicators?

Tire wear indicators can be located by finding the small triangle marks on the sidewall of the tire. Following the direction of these triangles, you will find raised horizontal bars within the tread grooves, which are the tire's wear indicators. Below is relevant information about tire wear indicators: 1. Safety Indicator: The wear indicator serves as the maximum warning line for tire tread wear. If the tread depth reaches or falls below 1.6 millimeters, the tire must be replaced. 2. Consequences: Performance on dry roads significantly deteriorates, increasing the risk of overheating and blowouts. Additionally, wet weather traction is greatly reduced, leading to potential hydroplaning and loss of control. 3. Maintenance Tips: (1) Regularly check tire pressure to ensure it is within the recommended range. (2) Promptly remove stones or debris lodged in the tread grooves. (3) Frequently inspect tires for cracks and wear, replacing them when necessary.

Is Passing Through After the Yellow Light Counts as Running a Red Light?

Running a yellow light and running a red light are both categorized under the same traffic violation—driving a motor vehicle in violation of traffic signal regulations. According to the "Road Traffic Safety Law of the People's Republic of China," this offense is punishable by a fine and 6 penalty points. Article 26 of the "Road Traffic Safety Law of the People's Republic of China" stipulates: Traffic signals consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light indicates permission to proceed, and a yellow light serves as a warning. The "Road Traffic Safety Law" specifies: A yellow light serves as a warning, and motor vehicles should slow down when approaching an intersection. If a vehicle has already crossed the stop line when the yellow light turns on, it may continue to pass through. If the vehicle has not crossed the stop line, it should come to a stop. The "Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China," Article 38, states for motor vehicle and non-motor vehicle signal lights: When the green light is on, vehicles are permitted to proceed, but turning vehicles must not obstruct the passage of through-moving vehicles or pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to proceed. When the red light is on, vehicles are prohibited from proceeding. At intersections without non-motor vehicle or pedestrian crossing signals, non-motor vehicles and pedestrians should follow the motor vehicle signal indications. When the red light is on, right-turning vehicles may proceed, provided they do not obstruct the passage of other vehicles or pedestrians. Electronic surveillance captures red-light running based on the following three photos, which are reviewed by traffic police to determine whether a violation occurred: An image of the vehicle not having passed the stop line when the red light is on. An image of the vehicle's front wheels crossing the stop line. An image of the vehicle's entire body having crossed the stop line. If these three photos show that the vehicle moved beyond the stop line while the red light was on, the traffic police can confirm the vehicle ran a red light during review. To avoid running a yellow light: Slow down when approaching an intersection, maintain a speed of 20-30 km/h, keep a safe distance from the vehicle ahead, and avoid tailgating or rushing through a yellow light. Alternatively, observe the signal light in advance; if the green light has been on for a long time and traffic is light, prepare to slow down.

What to Do If the Car Stalls During Hill Start in Subject 2 Driving Test?

During hill start, when the left foot slowly releases the clutch pedal until the vehicle starts to vibrate, it should be slightly held at this position to confirm whether the vehicle has the tendency and power to move forward. Do not continue to lift the clutch pedal to prevent stalling. Relevant explanations are as follows: 1. Brake before clutch: The throttle has no travel, while the clutch does. The so-called travel refers to the process from the action taken to the effect produced. When braking, brake before clutch. 2. Avoid stalling: During the test, stepping on the clutch first is considered coasting in neutral. When the brake is continuously pressed to a certain extent, the car body will shake, indicating that due to the resistance of the brake, the engine can no longer drive the gears to rotate and perform work. At this time, the clutch needs to be pressed down to cut off the power transmission of the engine, thereby avoiding stalling.
