Gasoline additives have a certain effect, but they are not as effective as ideal. First of all, it is mainly developed to target carbon deposits in engines. The additives in it are supplemented by the maintenance of oil circuits and the cleaning of sulfur and colloids in the fuel. Therefore, gasoline additives can, to a certain extent, promote the combustion of gasoline, improve the power of the car, and play antioxidant, demulsifying, and lubrication functions.
However, as for engine carbon deposits, after using Fuel Treasure, it can only be said that the generation of carbon deposits is reduced and the combustion efficiency of gasoline is improved. But when it comes to removing carbon deposits, it cannot be solved by just using a few fuel bottles. Basically, you have to go to a professional maintenance store or 4S shop and use professional equipment for cleaning.
It is precisely because its effect is not obvious enough that so many car enthusiasts question whether the fuel treasure is useful. In addition, there are too many brands of fuel treasures on the market, and there are many fake and shoddy products among them. Buying such products will not only have no effect on cleaning carbon deposits, improving power, and maintaining oil circuits, but will even increase engine wear. As a result, there will be more doubts.
In fact, domestic gasoline itself contains certain fuel additives, so the need for additional fuel additives is not great, but overall, using fuel additives will produce less carbon deposits than not using them.
