Understanding What a Fuel System Cleaner Does
When I first looked into fuel system cleaners, I wanted to know exactly how they work. These cleaners help remove deposits from your fuel injectors, intake valves, and combustion chambers. This can improve engine performance, fuel efficiency, and reduce emissions. Knowing this, I realized the importance of choosing a high-quality product that truly cleans and protects my engine.
