It is best to use a Gas Additive as well and so that you get the full potential of cleaning the injection system you should use with a full tank of gasoline. Cleaning injectors, throttle body and the air intake should be done as a complete service. Dirty Fuel Injectors can affect the engines performance. Leaking Fuel Injectors and or Fuel Injector seals are an extreme danger and can cause a fire. It is not safe to drive a vehicle with leaking Fuel Injectors or Injector Seals.
