Are Fuel Additives Useful?

[GarrettDella]

Fuel additives have fuel-saving and cleaning effects. Cleaning effect: The effect of this function is not immediate, and its value can only be reflected through long-term use. Engines that use fuel additives over a long period will definitely have much less carbon buildup. Fuel-saving effect: Additives also have a fuel-saving effect, although it is not very significant, with savings of only about 5%. The effect may be slightly more noticeable for vehicles that frequently travel long distances. The quality of additives available on the market is hard to guarantee, and using inferior additives can be harmful rather than beneficial. It is best to purchase them from 4S stores, although the price may be higher, but at least you can hold them accountable if any issues arise.
