Default SeaFoam

OK, I was out on a F150 forum looking up some stuff for my 01 F150 5.4ltr 4x4 lariet.

I cam accross a thread on SEAFOAM a product that has been around for generations and is cheap. They say by sucking about 5oz through the brack booster vacuum hose then the rest of the can in your fuel tank (w 10 gal left) it will clean all the tarnish in the upper motor and your fuel system.

they are saying it is the best and they have noticed performance gains and improved MPG on trucks with only 32K on them.

Thought I would bring this up here as I know the knowledge and reputation of this forum is reliable.
My question is how can a $4.5 can of SeaFoam that is suppose to do all this and be around for generations not be well know, or are they talking trash?

I used it on my 79 3/4 ton chevy truck with some 200,000 miles. It made the truck smoke bad for about a week. But after that it stopped smoking and ran just fine. : :cool:

A guy in our Vette club has worked on plane, boat and car engines for years. He claims that you can clearly see the difference on a tore down engine that has used Seafoam. All passages clean; no sludge; piston walls like new. It can be used in the crankcase or fuel. If used in the crankcase he claims you should change the oil within 500 miles. I did this with a fresh oil change and the oil came out dark, telling me it was cleaning out the sludge. This product can be used in 2-stroke or 4 cycle engines. It will act a gas stablizer as well. I have now been using it for a couple of years, in cars, and power equipemnt with very good results with no side effects. It has helped rough idling problems and increased my oil pressure about 10psi on my older C3.

I've had great results with SEAFOAM. I have ran it in my oil to loosen sticking valves and lifters. You do have a period of noise, but the end result has been good.

Seafoam is great stuff, but a word of caution about sucking any liquid through a vacuum hose. You want to trickle it in slowly because if you were to suck it right out of the can you could hydro lock the engine and bend a rod. I have heard of this happening a few times. Craig

GM also sells a "Top Engine Cleaner" that works well for carbon deposits. I have always had good luck with seafoam and recommend it.
