What is the function of gasoline additives?

The following are the functions of fuel additives: 1. Remove carbon deposits and clean the fuel system: The new generation of fuel additives contains cleaning activation factors that can promote the harmful substances such as colloids in the fuel and engine carbon deposits. After adding fuel additives for 5 consecutive times, the carbon deposits on the exhaust pipe are significantly reduced, and the filter, exhaust valve, fuel system, etc. are all very clean. 2. Enhance power performance: The nano-components in the new generation of fuel additives can adsorb and wrap colloids, and under high temperature, they produce gaseous "micro-explosions" in the combustion chamber, causing secondary atomization of the fuel and complete combustion, thereby improving engine power. More than 90% of vehicles feel a significant increase in power after the first use of fuel additives. This is especially noticeable when the car is sluggish, old, carrying heavy loads, or traveling long distances.
I usually pay great attention to car maintenance. Gasoline additives mainly address three pain points: First, they clean carbon deposits, especially for direct-injection engines where fuel injectors are prone to clogging. Additives containing PEA can dissolve stubborn carbon buildup. Second, they boost octane levels—older cars running on 92-octane fuel are more likely to experience knocking, and using additives is like a temporary fuel upgrade. Third, they protect the fuel system. I've seen many cars with fuel pump filters clogged by gum deposits, and regular use of additives can slow down fuel system aging. Once, my car idled roughly, but after using two bottles of additive, the throttle response became noticeably smoother. When the mechanic disassembled the engine, they found that most of the carbon deposits were gone.
Adding fuel additives is like giving your car health supplements, with the most practical benefits being carbon deposit cleaning and fuel saving. During my last maintenance, I found the piston tops covered in black sludge, and the mechanic said it would increase fuel consumption. Out of curiosity, I tried a bottle, and now on the highway, I save 0.8 liters per 100 kilometers. The key ingredient, polyetheramine, wraps around carbon deposits and expels them with the exhaust. It works best when added with a quarter tank of fuel left. For city drivers with frequent short trips, it's recommended to add it every 5,000 kilometers, especially for China VI vehicles with strict emission standards—repairing a clogged catalytic converter can be really expensive.
