How to Deal with Scratches Caused by Opening Car Doors?

Minor scratches caused by opening car doors can be treated by applying toothpaste to the affected area and gently rubbing it. The fine particles in toothpaste help to gradually polish away the visible scratches. Minor damages to vehicles are often unavoidable in daily life. If they do not affect the overall appearance of the car, it is not recommended to treat them. However, when necessary, toothpaste can be gently rubbed on the scratches. Additionally, regular waxing or applying anti-wear patches to vulnerable areas can help prevent minor scratches to some extent. When there are very clear scratches on the paint or marks left by friction with objects, it is advisable to use a touch-up pen for treatment. Touch-up pens can repair, conceal, and fill in the damage. They typically contain the original car paint, and since different car models have specific paint colors, only the dedicated touch-up pen for the particular car should be used. However, areas treated with a touch-up pen may appear uneven.

What are the symbols for BMW's internal and external air circulation?

In BMW vehicles, the letter 'A' illuminated indicates external air circulation, while the letter 'M' illuminated represents internal air circulation. Below is an introduction to the related content: 1. Letter symbols: The central control button features both the letter 'A' and the letter 'M' on the same button. 2. Appearance shape: There is also a shape resembling the exterior of a vehicle, with a curved arrow inside. Below are the differences between internal and external air circulation in terms of closing the air intake: 1. Internal circulation: When using internal circulation, the vehicle's interior space acts like a sealed environment. Whether it's cold or hot air blown by the air conditioning, it circulates within the car, with no fresh air entering. 2. External circulation: When external circulation is turned on, fresh air from outside flows into the car, improving the air quality inside the vehicle, which is also a beneficial way to use it.

What does 235/65R18 mean?

Tire specification 235/65R18 is the tire size code. In 235/65R18, 235 represents the tire width of 235mm, 65 represents the aspect ratio of the tire's height to width as 65%, R indicates that the tire is a radial tire, and 18 means the tire fits an 18-inch wheel rim. The following is relevant information about tires: 1. Wider tires consume more fuel: The wider the tire, the larger the contact area. Under the premise of the same tread pattern and material, wider tires provide better grip and traction when driving straight, but fuel consumption will increase accordingly. 2. Classification of tires by usage: including load-carrying tires, passenger car tires, and mining tires, etc. Load-carrying tires must indicate the ply rating on the sidewall in addition to the size specifications. The ply rating of load-carrying tires does not refer to the actual number of layers but indicates that the tire body made of high-strength material cords has a load performance equivalent to that of a tire body made of cotton cord layers.

Are Antifreeze and Coolant the Same Thing?

Coolant and antifreeze are the same thing with no difference. The full name of antifreeze is antifreeze coolant. Below is relevant information about antifreeze: 1. Consequences of mixing antifreeze: Since different brands of antifreeze have different formulations, mixing them can cause chemical reactions. 2. Effective usage period of antifreeze: Typically, the effective usage period of antifreeze is two years, and it needs to be replaced when it expires or if the coolant appears dirty. 3. Introduction to antifreeze: The full name of antifreeze is antifreeze coolant, meaning it is a coolant with antifreeze properties. It prevents the coolant from freezing and expanding in cold winter conditions, which could crack the radiator or damage the engine cylinder block or head. 4. Functions of antifreeze: Many car owners believe that antifreeze is only used in winter, but in fact, antifreeze should be used all year round. It is a type of coolant with special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion throughout the year.

215 represents the tire width of 215 millimeters, 55 is the aspect ratio of 55%, R stands for radial tubeless tire, 17 is the rim diameter, and 94v corresponds to a load capacity of 670kg and a maximum speed of 240Km/h. Below are relevant introductions about tires: 1. Tire representation: Tire specifications are commonly represented by a set of numbers. The first number indicates the tire section width, and the latter indicates the rim diameter, in inches. For example, 165/70R14 means a tire width of 165 millimeters, an aspect ratio of 70, and a rim diameter of 14 inches. 2. Symbol meanings: The letters or symbols in the middle have special meanings: "X" indicates a high-pressure tire; "R" and "Z" indicate radial tires; "—" indicates bias-ply tires. For example, 6.00—12, a bias-ply tire, is only used in some low-end off-road vehicles and heavy-duty trucks due to its poor safety, load capacity, and high-speed stability.
