Fuel injector cleaner is a chemical additive designed to clean and maintain the fuel injection system in a vehicle's engine. It works by removing carbon deposits, gum, varnish, and other contaminants that accumulate on the fuel injectors and in the combustion chamber over time. These deposits can clog the injectors, reducing fuel flow and engine efficiency, leading to symptoms like poor fuel economy, rough idling, engine misfires, difficulty starting, and loss of power
. The cleaner typically contains chemicals such as polyetheramine (PEA) or polybutene amine (PBA), which break down and dissolve these deposits. When added to the fuel tank, the cleaner mixes with the gasoline and flows through the fuel system, cleaning the injectors and lubricating the fuel system components to reduce friction and prevent future buildup
. Using fuel injector cleaner regularly helps restore the fuel system's efficiency, improves fuel combustion, enhances gas mileage, smooths engine performance, and lowers emissions. It is recommended to use the cleaner every 15,000 to 30,000 miles depending on the vehicle and driving conditions. For best results, the cleaner is added to a nearly empty fuel tank before refilling
. In summary, fuel injector cleaner:
- Removes carbon and other deposits from fuel injectors and combustion chambers
- Improves fuel efficiency and engine performance
- Helps maintain smooth idling and reduces engine stalling
- Lubricates the fuel system to prevent future buildup
- Can extend the lifespan of the fuel injection system
