Is It Necessary to Use Gasoline Additives?

[McXavier]

It is not mandatory to use them. Here is a relevant introduction about the functions of fuel additives: Cleaning effect: The effect of this function is not immediate; its value can only be reflected after long-term use. Engines that use fuel additives over a long period will have significantly less carbon buildup. Fuel saving: Additives also have a fuel-saving effect, though it is not very noticeable, with savings of only about 5%. The effect may be more pronounced for cars that frequently travel long distances. The quality of additives available on the market is hard to guarantee, and using inferior additives is harmful rather than beneficial. It is best to purchase them from 4S stores, even though the price may be higher, as at least you can hold them accountable if any issues arise.
