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.

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).
