Is it necessary to add fuel additive?

It is necessary to add fuel additive to your car. Fuel additive can effectively eliminate carbon deposits and other issues. However, excessive use or inferior products can cause fatal damage to the engine, such as engine knocking or detonation. The functions of fuel additive: The role of fuel additive is to solve the carbon deposit problem in the fuel system of electronically injected vehicles, quickly restore the engine's optimal working condition, and compensate for certain deficiencies in gasoline properties. It also imparts new beneficial characteristics to gasoline, such as improving atomization, reducing wear, protecting the engine, and lowering emissions. Precautions when adding fuel additive: Currently, the common fuel tank capacity for small family cars on the market is 35-45L, mid-size cars around 55-75L, and large or luxury cars around 75-100L. The standard specification for fuel additive is usually 60ML, which can be mixed with 30-60L of gasoline. Therefore, a typical family car's full tank of fuel requires 1-2 bottles of fuel additive. The exact amount to be added should be determined based on the specific condition of the car.
I think the issue of adding fuel additives is quite interesting, especially if you drive an older car with some mileage or frequently drive at low speeds in the city. The engine is prone to carbon buildup, and fuel additives, as cleaning agents, can help break down some of that carbon, making combustion more efficient. Essentially, fuel additives work by using certain chemical agents to penetrate the fuel system and clean deposits in the injectors and combustion chambers. This not only improves acceleration response but can also slightly improve fuel efficiency—roughly allowing you to drive an extra few dozen kilometers per tank. However, for new cars, there's no need to fuss over it. The manufacturer's design is already optimized, and randomly adding additives might conflict with the original fuel system, causing adverse effects. In short, it depends on the car's condition. I generally recommend adding one bottle per maintenance interval or between fuel refills—not too frequently—to save money and protect the car.
