Fuel injecter cleaner?

[Disturban]

What do you use? I was going to try some Z-max until I seen the $35 price tag. I am glad I did not get it because when I got home I decided to try to find out what the active ingredients was in it. And I ran across a bunch of websites that say it's snake oil....Mmmm imagine that I ended up buying old faithful (GUMOUT) I figure they have been around before I was born must mean they are doing something right. But after doing my home work I found alot of people have good things to say about Chevron TECHRON as well Lucas and Seafoam. My opinion is if you change your fuel filter every 6 months, run good fuel with cleaners already in it Mobil, Amoco ect ect you should never have to clean your injectors. However my Burban is 20yrs old and I bet it has never been changed. She started to run bad the last few days so I got a new filter, injector cleaner (GUMOUT) new plugs, wires, cap and rotor and we will see what happens this weekend.

I guess I would just like to know what everyone else thinks about cleaning their injectors and what products you have faith in and why?

Seafoam is great stuff. Used to use it. Now I stick with the STP (cheaper) for the most part. My C1500 probably has the original fuel filter in it but she still runs like a top. I know the bottle I gave grandpa for his '84 helped it out alot. For the bad runners I usually use about double the dose.
