I'm usually not an impulse buyer of additives, but so many people recommended Seafoam to me that I gave it a shot. Now, I have used it on everything I own, from chainsaws to my 'vette to my dirtbike. While it is basically glorified carb cleaner - it really worked for me. I did this back in April and I am going to do it again to my 'Vette in a week or two when I get bored and need something to do 
.
This is how I Seafoamed my '84.
I removed the air cleaner from the crossfire and dumped approximately half a can into each of the TBI's through a funnel while the car was running. You have to pace the flow, don't just dump it straight in. Then I shut off the car and dumped another 1/2 can into each TBI so it could sit (next time I will be using more here). Then I put something like a 1/4 of a can into the crankcase, and I dumped a full can into the gas tank.
Then I got in the car and tapped the starter just a hare a few times. I then let the car sit for several hours. Next time I will let it sit overnight at this point.
When I went to fire it up, I knew it wouldn't start right away. So I cranked, let it sit for a minute. Cranked, repeat... until she fired up. Beware, smoke will be immense at this point. I then took her out for a cruise and went on some errands, blowing plumes of smoke like I have never seen in my life.
The next step for me was changing the oil after maybe 400 or 500 miles. The Seafoam itself will not hurt anything in your engine, but all the crud it frees up could clog your oil filter over time. Just to be safe I changed it, rather than wait until my next "scheduled" oil change.
While I realize I probably could have got the same result without using so much seafoam, at $5 bucks can, I figured why not.
The biggest benefit came from pouring it in the TBI's. I really feel it got rid of a lot of carbon, and it removed the weird smell that occasionally came from my exhaust (probably was the cat starting to foul/clog). The car runs smoother and idles better. Any restored "power" is probably just in my head however, but it felt like I gained a little back. I did see a slight jump in gas mileage, my average went from 18 to the current 19.6, but there are too many other factors that can affect that for me to blame the Seafoam.
I am not sure it did anything in the crankcase and gas tank (I hoped it would clean the fuel filter and the lines a little bit), and if I had old seals I don't know that I would use it in the oil as it might remove some crud built up around them and cause small leaks.
Anyway, that's just how I did it, and I was wondering if anyone else had any luck with the Seafoam? I am tempted to buy their "Trans Tune" crap too for when I flush my ATF, after my experience with the regular Seafoam I figure it's worth a shot.
