Is it okay to add a bottle of fuel additive to half a tank of gas?

[LaValerie]

Whether adding a bottle of fuel additive to half a tank of gas will affect the car depends on the mixing ratio specified in the fuel additive's instructions. If the mixing ratio is not 1:2, it may affect the quality of the fuel. Below is some relevant information about automotive fuel additives: Function: Fuel additives, commonly known as the third generation of gasoline detergents (also referred to as gasoline detergents or fuel additives), are designed to address carbon buildup in the fuel system of fuel-injected vehicles, quickly restore the engine to optimal performance, and compensate for certain deficiencies in gasoline while imparting new beneficial characteristics (such as improved atomization, reduced wear, engine protection, and lower emissions). Composition: Fuel additives primarily consist of more than ten components, including nano-molecules, cleaning activation factors, antioxidants, anti-corrosion agents, and demulsifiers. They are specifically developed to target harmful substances in fuel, such as sulfur, gum, and engine carbon deposits, thereby enhancing power, promoting combustion, providing anti-oxidation, anti-wear, cleaning, dispersing, demulsifying, anti-corrosion, and lubricating effects.
