Pickup Loss

I checked out the Seafoam links and I'm not really sure I want to put that stuff in my system.
Is this what some Mechanics use when cleaning Injecter's at the Dealer's/Shop's?
The Regane and Others that you would pour into your tank seems like you would have to do this on a continueing basis Everytime filling up with fuel. Being a dummy over here asking the dumb question's etc., I thought there would be something out there that you just pour into the tank and your good to go for another X amount of more miles (instead of a bottle each time at fill up...unless, by doing this, this cleans the system over a period of time?). Honestly, I think this could be the issue, dirty injecter's. And, as Other have said on here, "it's a start".
