How did you guys Sea Foam?

About to do it for the first time just to flush the gunk out but also to check for exhaust leaks.

I have an '04 GT with about 64,000 miles on it. Do I need to put it in the oil as well?

Good idea to change the oil afterwards if that's the case?

I planned to just put half in through the PCV vacuum and half in the fuel tank with a little over half a tank of 93 fuel.

Nevermind. Put half in through the plenum and poured the other half in the fuel tank. Got a little bit of smoke but not as much as the videos I've seen.

Mine smoked pretty good but I did it at 80k. How long did you let the car sit before you started it?

The longer you wait (within reason 5 - 7 mins) the more the chemical gets a chance to loosen up the carbon build up.

I did half a can through the intake. Mine smoked a little but not bad.
