What is the purpose of fuel additive?

[ArielMarie]

The purpose of fuel additive is to solve the carbon deposit problem in the fuel system of electronic fuel injection models, quickly restore the optimal working condition of the engine, and compensate for certain defects in gasoline properties, giving gasoline some new excellent characteristics. Functions of fuel additive: The functions of fuel additive are to solve the carbon deposit problem in the fuel system of electronic fuel injection models, quickly restore the better working condition of the engine, and compensate for certain defects in gasoline properties, giving gasoline some new excellent characteristics, such as improving atomization, reducing wear, protecting the engine, and lowering emissions. Precautions for adding fuel additive: Currently, the common fuel tank capacity for small family cars on the market is 35-45L, medium-sized cars are around 55-75L, and large or luxury cars are around 75-100L. The common specification of fuel additive is 60ML, and usually, 60ML can be mixed with 30-60L of gasoline. Therefore, a common family car typically requires 1-2 bottles of fuel additive per tank of fuel. The specific amount to be added should be determined based on the specific situation of the car.

I've been driving for almost ten years and have consistently used fuel additives. These products mainly address two issues: one is removing carbon deposits in the engine, especially in critical areas like fuel injectors and intake valves—excessive carbon buildup can make the car feel sluggish; the other is improving combustion efficiency, making gasoline burn cleaner. My old car used to feel stuffy during acceleration with higher fuel consumption, but after three months of using fuel additives, I noticed the throttle became more responsive, and fuel consumption dropped by about 0.5 liters per 100 kilometers. Nowadays, new cars undergo cleaning before leaving the factory, but carbon deposit issues still emerge after running 40,000 to 50,000 kilometers. I usually add one bottle every 5,000 kilometers and find it quite effective for engine maintenance.

When repairing cars, it's common to encounter complaints from car owners about lack of power during acceleration or higher-than-normal fuel consumption. In most cases, opening up the engine reveals black carbon deposits. Fuel additives act like engine cleaners, with their active ingredients breaking down gum and carbon particles in the fuel system. Especially for direct injection engines, where fuel injectors are prone to clogging, using fuel additives results in more uniform fuel atomization. However, it's important to distinguish between cleaning-type and maintenance-type additives. Cleaning-type is suitable for use every 5,000 kilometers, while maintenance-type can be added long-term. I recommend choosing products from major brands, as off-brand additives may corrode fuel system seals.

I think fuel additives are related to environmental protection. Previously, my vehicle failed the emissions test, and the mechanic said it was due to incomplete combustion. Fuel additives help gasoline burn more completely, thereby reducing carbon monoxide and hydrocarbons in the exhaust. Now, I add a bottle when refueling, and I feel the exhaust smell is less pungent, and it's easier to pass the annual inspection. Although it doesn't reduce total carbon emissions, cutting down on harmful gas emissions does help improve air quality. I recommend friends who often drive in urban areas to try it, as traffic congestion areas are more prone to carbon buildup.
