I'm actually only guessing. I add it to my gas and just assume it's performing as advertised (cleaning fuel injectors and other internal engine parts).

Recently decided to start using this again. I've had good experiences in the past. Several years ago it helped after my engine was a little rough at start up due to dirty fuel lines and/or moisture in the tank.
