Every vehicle has a fuel injection system in it. The function of a fuel injector is to spray gasoline into the engine, so it can sustain the internal combustion process. However, these fuel injectors will get cluttered with debris as time goes on. Contaminants like wax, dirt, carbon particles and additives will negatively influence the injectors and cause them to malfunction. Dirty fuel injectors could spray fuel at irregular patterns into the engine, which would cause your gas performance and gas mileage to suffer for it. As time goes on, you will have trouble starting your vehicle until the time comes when you can’t start it at all.
