What is the correct way to use fuel additive?

[OIsabela]

The correct way to use fuel additive is: pour it directly into the gasoline tank. However, it's important to note that you must add the fuel additive before refueling with gasoline. This allows the additive in the tank to mix thoroughly under the impact of the incoming gasoline, thereby achieving better results. Although fuel additives can indeed provide excellent fuel characteristics, prolonged use may cause varying degrees of impact. Fuel additive is an automotive chemical product, also commonly known as the third generation gasoline detergent. It can quickly restore engine performance, compensate for certain deficiencies in gasoline properties, and impart new excellent characteristics to gasoline, such as improving atomization, reducing wear, protecting the engine, and lowering emissions.
