Thread: Tried Seafoam on my car with no smoke? did i do it right?

Ehh this can be debated, some people say the carbon makes the smoke. I whole-heartedly disagree, seafoam is an oilbased product the smoke comes from the oil You should be seeing smoke no matter what.

It can be debated, but I have run it on cars for the first time and made enough smoke to engulf a two-story house. Doing the same thing one year later, the smoke was very minimal. I fail to see any other contribution to the smoke other than build-up in the engine. I have never seen smoke made when adding half of a can to an almost empty tank of gas, or adding it to the oil just before a change.

I also know a guy that gets similar results using water.

I always seafoam, we seafoamed our Jeep last year when we bought it brand new and still got the smoke show. Not once when I have used it, did it let me down in that aspect, that being said I also believe that the carbon build up plays a part in it and you will more then likely get more smoke with more build up. Now that brings me to the second part, some people also say using seafoam can hurt your engine as it breaks off large parts of carbon instead of breaking it down into much smaller pieces (I disagree because I have never seen huge chunks coming out of the exhaust).

Well driving habits also play a big role in the amount of carbon buildup present. If you drive your car hard often you'll more than likely not have that much carbon buildup compared to a car that rarely ever gets driven hard. My car barely smoked at all when I seafoamed it for the first time at 140K, but that makes sense since I regularly beat on it .

So since you got some expierence... Is there anything wrong with doing this? Does it harm the engine? Is there ANY reason you wouldn't do this to a car? I own a 2001 Grand Prix GTP. No mods to the engine.
