The difference between tire noise and bearing noise: The main difference lies in the sound. Tire noise is the friction sound generated by the rolling of the tires, while bearing noise is a metallic friction sound. Additionally, tire noise occurs when the vehicle is driving at high speeds due to the friction between the tires and the road surface, and the level of tire noise is determined by the road conditions—the worse the conditions, the louder the tire noise. Below are methods to determine if a bearing is faulty: 1. Jack up the car: Lift the car's tire (using a jack is also acceptable). 2. Rotate the tire: Quickly rotate the tire by hand and place your fingers on the shock absorber. If you feel vibrations, the bearing is definitely problematic.

What are the precautions before using ethanol gasoline?

Precautions before using ethanol gasoline include: cleaning and inspecting the main components of the car's fuel tank and fuel lines to ensure the cleanliness of all parts of the fuel system. Ethanol gasoline is an alternative energy source formed by blending fuel ethanol, processed from grains and various plant fibers, with gasoline in a certain proportion. Precautions for using ethanol gasoline are: the fuel supply system must not contain water, as water in the fuel tank can mix with denatured fuel ethanol, affecting the normal operation of the engine. The impact of using ethanol gasoline on cars is: ethanol gasoline contains oxygen, has a lower calorific value than gasoline (about two-thirds that of gasoline), and has different evaporation pressure characteristics, which can affect the vehicle's power performance.

What is the best engine oil for Beijing Hyundai?

Beijing Hyundai vehicles perform best with the original Beijing Hyundai API SM/GF-4 SAE 5W-20 engine oil. Below is additional information about engine oil: 1. The "0W-30" label on the engine oil packaging refers to the oil viscosity grade, which is classified according to the SAE standard. "W" stands for winter, and the smaller the number before it, the better the oil's low-temperature fluidity and the better it protects the engine during cold starts in lower environmental temperatures. The higher the number after the "W," the higher the oil's viscosity at high temperatures, providing better lubrication for the engine. 2. Semi-synthetic and fully synthetic oils are two categories of engine oil. The difference is that fully synthetic oil has a wider operating temperature range and a longer service life. Under the same working conditions, fully synthetic oil can protect the engine with a lower viscosity.
