Several years ago, when the Internet was not so well developed, and it was almost impossible to get additives for the engine, there were myths that there was a “chemistry” that could seriously reduce fuel consumption. It is now clear that fuel economy additives can indeed be added to the engine.
Most often, gasoline additives allow you to start saving 8-10% of fuel, but this is not due to their wonderful composition, but due to their cleaning of the engine. Gasoline additives to save fuel are nothing more than a cleaner for the fuel system of a car. They work at the molecular level and, penetrating into the engine, remove carbon deposits that arise during engine operation. Together with the fuel, the additives move through the fuel pumps, valves, and the combustion chamber and clean them equally effectively as an injection engine and a carburetor engine. The use of such additives is justified when there is a sharp lack of engine power or a violation of the stability of the car at idle. This can happen after refueling at an unchecked station or if dirt gets into the gas tank by other means. It is rather difficult to clean the fuel system in any other way than with additives.
