Default Seafoam

How often should I seafoam? I think i seafoamed about 1 year ago about 10000 miles or so. I put it through the vaccum line, the fuel tank, and the oil. Then changed it. However not much smoke. I had about 90000 miles on her. Now about 101000. Should I seafoam again? How often should i seafoam? And, Should I follow the same procedure as i did last year with the seafoam? Also one last question, is it reccomended to change the oil after seafoaming? What exctly does it do when you pour it in the gas, the oil, and let vaccum suck it up? THANKS ALOT

Unless your having problems with a lot of deposits, I say don't. Your really don't want to do it to much, it drys out O rings and gaskets.

Does seafoam actually work at cleaning out engine deposites? I'm new to the gm world (used to be a ford guy) I now have a 2006 GMC Sierra and it has 110,000 miles on it. I have already switched to mobil 1 engine oil, dex 6 trans fluid, and changed the transfer case and differential fluids to synthetic, flushed the coolant and changed the air filter. I really love this truck and want to keep it running for a long time. I thought about Zmax until I found that they are being sued for false advertising. I hear more people using Seafaom. I am do for an oil change soon, how do I use it and how often do I use it?

Thanks for all the advise.

Yes, it does work, and pretty well too. Basically disconnect the brake booster vacuum line and pour it in slowly, then shut off the engine, let it sit for 15 minutes or so, and fire it back up and go out and do some hard driving. Don't pour it in too fast.

There are a lot of youtube videos out with people showing how to do it.
