Premium gasoline is also called high-grade gasoline, which refers to gasoline with certain anti-knock agents, combustion aids and other ingredients added to ordinary gasoline. The octane number of this type of oil is generally greater than 90, so it can better protect the engine and make the engine work more smoothly. Regular gasoline is a common fuel used as a power source for internal combustion engine vehicles. It is usually a mixed hydrocarbon compound, mainly composed of carbon and hydrogen. It has a moderate octane number, usually between 87 and 91, and appropriate volatility and ignition properties.

Why do automotive professionals recommend using premium gasoline instead of regular gasoline? What is the difference between premium gasoline and regular gasoline? What are the advantages of premium gasoline that regular gasoline does not have? Keep reading, this article will reveal the answer for you.

Because premium gasoline has a higher octane number, it exhibits excellent anti-knock performance. The quality of anti-knock performance directly affects the operating stability and safety of the engine. Compared with low-grade gasoline (such as 92), high-grade gasoline (such as 95) can provide better anti-knock performance and reduce the power loss and fuel consumption increase caused by engine knock.

At the same time, premium gasoline has a relatively low impurity content, especially reducing the content of harmful substances such as sulfur, which helps to reduce pollution emissions.

Compared with ordinary gasoline, premium gasoline burns more completely and can effectively reduce the formation of carbon deposits in the cylinder. Premium gasoline can provide more stable combustion efficiency during the combustion process, thereby reducing the formation of carbon deposits and keeping the engine clean. This helps to improve the performance and life of the engine.

What's more, using premium gasoline can reduce the need for engine maintenance. Because its better combustion efficiency can reduce the formation of deposits, thus reducing the risk of engine failure. In addition, premium gasoline can also improve engine performance to a certain extent.

Although premium gasoline has many advantages, its higher price has become a major problem. Due to the higher production costs of premium gasoline, including higher refining technology and stricter quality control, its market price is usually higher than regular gasoline. At the same time, premium gasoline has a limited scope of application. Premium gasoline is mainly designed for high-compression ratio engines, which are usually installed in high-end models or performance cars. Therefore, ordinary cars or low-power engines do not need high-grade gasoline, and using it does not bring obvious advantages.

For some qualified used cars, it is also necessary to use premium gasoline. Since used cars have been used for a long time, they need to be maintained more carefully. Using premium gasoline can effectively protect the car's engine. Premium gasoline generally contains more additives, such as detergents, antioxidants and lubricants. These additives can effectively clean and protect the engine's combustion chamber, nozzle and cylinder wall, reduce the accumulation of carbon deposits and impurities, and extend the engine life.
