Can I Add Fuel Additive When There's Half a Tank of Gas Left?

[StLouis]

You can add fuel additive when there's half a tank of gas, but you should not mix it according to the proportion for a full tank. Fuel additive, commonly known as fuel system cleaner, is designed to compensate for certain deficiencies in gasoline and impart new beneficial properties. It helps clean system carbon deposits, increase octane rating, improve atomization, reduce wear, and protect the engine. New cars do not require fuel system cleaners since carbon deposits have not yet formed. Generally, after driving 10,000 kilometers, a small amount of carbon deposits may form, at which point a qualified fuel system cleaner can be used. Relevant information about car maintenance is as follows: A driver's habits have a greater impact on the car than using fuel additives: For example, if a car frequently drives slowly in the city with frequent stops and starts, it is prone to engine carbon buildup. If the car often travels on highways, carbon deposits are less likely to form, and even if the mileage exceeds 200,000 kilometers, fuel additives may not be necessary. Bad habits: Many drivers tend to accelerate or brake abruptly, which increases fuel consumption. Using fuel additives cannot compensate for these poor driving habits. Regular car maintenance and periodic carbon deposit removal can also achieve the same effect as using fuel additives.
