BMW X3 starting abnormal noise is mainly caused by brake system failure or foreign objects in the tires. Brake system failure: In southern regions, due to the humid and rainy climate during spring and autumn, long-term driving in such conditions can gradually cause brake discs to rust. Especially for vehicles whose chassis have been submerged in water, the brake discs are more prone to oxidation and rust. Foreign objects in tires: When there is abnormal noise during starting, foreign objects may be lodged in the tread patterns of the wheels, causing the noise. These could be screws, stones, or other hard objects. Simply removing the foreign objects from the wheels can resolve the noise issue.

Why can't Youlian oil be used?

Youlian oil can be used. Here is the relevant introduction about engine oil: 1. Introduction: Engine oil, also known as engine lubricant, with a density of approximately 0.91×10³ (kg/m³), serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is hailed as the 'blood' of a car. Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, endowing it with certain new properties, making it an important component of lubricating oil. 2. Classification: Engine oils on the market can be simply divided into mineral oil and synthetic oil based on their base oil (vegetable oil is not considered due to its scarcity). Synthetic oils are further divided into full synthetic and semi-synthetic.

Do silver wheels look bigger or black wheels?

Silver wheels appear larger. Below is relevant information about wheels: 1. Introduction: The wheel hub is the rotating part that connects the tire's inner contour wheel steel through pillars, i.e., the metal component mounted on the axle that supports the tire. It is also called a rim, steel ring, or wheel. Wheel hubs come in various types based on diameter, width, forming method, and material. 2. Types of wheel hubs: Wheel hubs are also called rims. Depending on the characteristics and requirements of different vehicle models, the surface treatment processes for wheel hubs also adopt different methods, which can be broadly divided into painting and plating. For ordinary vehicle models, less consideration is given to the appearance of the wheel hubs, with good heat dissipation being a basic requirement. The process mainly involves painting treatment, i.e., spraying followed by electric baking, which is cost-effective and results in bright colors that last a long time. Even when the vehicle is scrapped, the color of the wheel hubs remains unchanged.
