What are the types of engine oil?

Engine oil is divided into three categories: conventional mineral oil, semi-synthetic oil, and full synthetic oil. The following are the relevant introductions: 1. Mineral oil: Mineral oil is a commonly used lubricant in the market. It is derived from the residual base oil after the refining process of petroleum, where useful substances like gasoline and aviation oil are distilled out. Essentially, it utilizes the inferior components of crude oil. 2. Semi-synthetic oil: Semi-synthetic oil is produced using semi-synthetic base oil, which is purified from mineral oil through hydrocracking technology. It is a mixture of mineral oil and full synthetic oil in a ratio of 4:6. The purity of semi-synthetic oil is very close to that of full synthetic oil, but its cost is slightly higher than mineral oil, making it an ideal transitional product from mineral oil to synthetic oil. 3. Full synthetic oil: Full synthetic oil is the highest grade of engine oil. It is derived from ethylene and propylene dispersed from natural gas or gas in crude oil, which then undergoes complex chemical reactions such as polymerization and catalysis to form a lubricating fluid composed of large molecules.

What are the solutions for car door squeaking?

Solutions for car door squeaking: 1. Lubricate the hinges: The door and body are connected by hinges, similar to a household door. It's normal for hinges to squeak over time. To ensure smooth and quiet operation, apply lubricant every 2-3 months for maintenance. 2. Clean the door limiter: Another component connecting the door and body is the door limiter. Open the door to its maximum angle, clean the grease and dirt from the limiter arm, pin shaft, and connecting bracket surfaces, then apply an appropriate amount of grease to the upper and lower surfaces of the arm. 3. Check for seal aging: If the car has been used for a while, inspect whether the door seals have aged. Since seals are made of rubber, they can deteriorate and crack over time, leading to noticeable wind noise and friction sounds. If the seals are aged or damaged, it's recommended to replace them directly. Additionally, regularly clean dust and rainwater from the seal gaps to prevent aging.

Is Tesla Afraid of Wading Through Water?

Tesla's ability to wade through water depends on the vehicle's wading depth. The maximum safe wading depth for a Tesla is approximately 138mm. Tesla's wading depth is determined by the height of the vehicle's chassis, which is the ground clearance listed in the model's parameter configuration table. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when driving through waterlogged roads. Therefore, in terms of safe wading depth, off-road vehicles and SUVs have obvious advantages. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a benchmark when driving through waterlogged roads. If the air intake is below the water level when a Tesla is wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it can cause severe damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth should not exceed the height of the engine's air intake. Alternatively, installing a snorkel can increase the height of the engine's air intake, thereby improving the maximum wading depth. If wading is unavoidable, the following safe and correct operations should be performed: Before wading, always turn off the auto start-stop function to prevent the engine from automatically restarting after stalling in water, which could cause severe damage due to water intake. Assess the underwater road conditions based on the passage of preceding vehicles and choose an appropriate entry point. Observe the path taken by other vehicles and follow it at a low speed, avoiding sudden acceleration or deceleration. On roads prone to water accumulation, use warning water level markers, trees, or other vehicles' wheels and doors as reference points to judge the water depth before deciding whether to proceed. Know your vehicle's safe wading depth. If the water depth exceeds half of the tire height or the engine's air intake, avoid entering the water and choose an alternative route instead.

Where is the engine number located in BMW series?

BMW series engine numbers are located on the engine block, at the connection point between the cylinder head front end and the engine block. BMW engine models consist of six digits, with the first three digits typically used as follows: 1. The first digit is an English letter, such as B, M, N, or S, which can be considered as the engine series; 2. The second digit is an Arabic numeral, commonly 4, 5, 6, or 7, representing the number of cylinders in the engine; 3. The third digit is also an Arabic numeral, indicating the configuration level of engines within the same series and type, which can be viewed as the engine's advancement level—the higher the number, the more advanced the engine. BMW cars refer to vehicles produced by BMW AG, with main series models including 1, 2, 3, 4, 5, 6, 7, and 8.
