A lot of people swear by it. If you get time do a search for seafoam or "cleaner" on here with DoctorD as the author. You'll find some good reading/discussion on the subject. That said DoctorD states that most all of those cleaners are alike with similar cheap ingredients and do very little. DoctorD has also said the the pure Techron cleaner is about the only one on the market that actually does something and is worth buying. I believe he uses that or a GM dealer/service grade cleaner.
I use to run the Lucas cleaner and liked it, however after learning what the doc had to say, any benefit/good it dis was probably all just in my head. I now use the Techron bottle.
