and got a little more gas mileage 14.7 to 15.2. Feels abit beeter than before.It has 68,xxx miles on it and just a small blue cloud came out. Was not all that dirty and it helped my idle too.

 

...I also did mine with Amsoils Power foam a few months ago...created a nice smoke show..lol..truck seems to run smoother...also cleaned my tb with it today and it feels stronger..

 

where did you put it in your engine at? i just bought a 04 5.7 ram quadcab with 72xxx,i am also getting about 14mpg city, 20mpg highway

 

Seafoam definitely works, I do it to all of my family's vehicles every 15 to 30k as a maintenance service. I did my wife's Toyota Matrix about a month ago and it helped with the cold start tapping we were experiencing. Must have been alot of carbon on the valves that got cleaned up.

I think I mentioned in the GM forums once how I bore-scoped different vehicles that I've worked on, before and after induction services, and how clean the combustion chambers got afterwards. I've used BG (pressurized), GM Top End, and Seafoam and they all seem to do the job well.

 

I seafoamed my avy at about 135000 mi, it spit out alot of smoke, and I inhaled it through the brake booster vacuum line

 

Through the vacuum line on the booster.
