What kind of fuel should I generally use for my car?

For cars, fuel is essential. Currently, the most commonly used fuels for small cars are 92-octane gasoline and 95-octane gasoline. In terms of price, 92-octane gasoline is indeed cheaper, but there is also a belief that 95-octane gasoline is of better quality. Many people today are enthusiastic about using higher-octane gasoline, even viewing the octane rating as a standard for fuel purity and quality. In reality, the gasoline octane rating only indicates the gasoline's octane number, which is its anti-knock property, and has nothing to do with purity or quality. In fact, the different types and prices of gasoline are based on their octane numbers. The octane number is an important indicator of gasoline's anti-knock performance. The higher the octane number, the better the anti-knock property and the stability of the gasoline. In terms of octane numbers, 95-octane gasoline is higher than 92-octane, so it has relatively better stability and naturally a higher price. Some car owners think 95-octane gasoline is too expensive and choose 92-octane to save on fuel costs. However, for cars that require 95-octane gasoline, using 92-octane gasoline over the long term may seem like a small saving, but it actually increases the frequency of engine knocking and accelerates wear and tear. Similarly, for cars that require 92-octane gasoline, higher-octane gasoline is not necessarily better. Blindly using higher-octane gasoline can lead to more carbon deposits, contrary to the traditional belief that higher-octane gasoline is cleaner and of better quality. It is recommended to carefully read the car's user manual, which usually provides detailed instructions, or check the label on the fuel tank.
