Fuel injector cleaners are specialized solvents. A solvent is simply a material that can dissolve another substance. The gas you put in your car usually has additives that are not good for your fuel system.

This can lead to less gas mileage and power in your vehicle. Fuel system cleaners basically attack the additives that have built up around your fuel system.
