How Effective is Fuel Additive?
2 Answers
Fuel additive is effective, as it can remove carbon deposits from the exhaust pipe, and also clean the filter, exhaust valve, fuel system, etc. The functions and composition of fuel additive are introduced as follows: Functions of Fuel Additive: Fuel additive, commonly known as the third-generation gasoline detergent (also referred to as gasoline detergent or fuel additive), is designed to address carbon deposit issues in the fuel system of fuel-injected vehicles, quickly restore the engine to optimal working conditions, and compensate for certain deficiencies in gasoline properties while imparting new beneficial characteristics (such as improving atomization, reducing wear, protecting the engine, lowering emissions, etc.). Composition of Fuel Additive: Fuel additive is mainly composed of more than ten components, including nano-molecules, cleaning activation factors, antioxidants, anti-corrosion agents, demulsifiers, etc. It is developed to target harmful components in fuel such as sulfur, gum substances, and engine carbon deposits, thereby achieving effects like enhancing power, promoting combustion, anti-oxidation, anti-wear, cleaning, dispersion, demulsification, anti-corrosion, and lubrication.
I've been driving for seven or eight years and have used fuel system cleaners a few times. I feel they can improve engine cleanliness and give a slight boost in power, especially making older cars run smoother. When chatting with friends about cars, they also mentioned a reduction in carbon deposits, but said it's a waste of money for newer models. Choosing reputable products is crucial—don't go for cheap off-brands. I tried a bottle from a small brand once, which had no effect and might even harm the engine. It's better to combine it with regular oil changes during maintenance. Think of fuel system cleaners as a supplement—don't expect dramatic changes. Keeping the vehicle in good condition is what matters most. Personally, I find the effects mild, and consistent long-term use can be beneficial.
