Bought a can at wally world for $8

Used 1/3 in brake booster 1/3 in oil (getting an oil change tomorrow) and 1/3 in gas tank.

Results, not much carbon and my engine has 103k miles


Barely any smoke

My Grand Am with 189K miles barely smoked, I used 2 cans on the G at 45K miles and that smoked like crazy.

I have yet to try this. I have only used it in the tank but have been slacking on putting it down the brake booster lines.

Stuff works pretty good i used it at 48k miles and was smoking like crazy

Brake booster is where the smoke happens

whats the purpose?

I did this last weekend and didn't see much smoke. Used 1/3 in brake booster and the rest in the gas tank since it was full.

excuse my ignorance but where is the brake booster at?

Pop your hood. It's the hose on the right upper corner. Check out videos on YouTube.

ok thanx

Right there. I used the straw method to get the seafoam in it.

did you get a service engine soon light

How long did you let the seafoam soak in if i may ask? The longer you let it sit and soak in the more it should smoke.

Nope

5-10 minutes. Next time I seafoam I'll let it soak for a good 30 minutes

Did it @ 100k. I drove around for about 15 minutes hard till it finally started to stop. But the rest in the tank. Overall i felt a lil difference but was more amazed by how much buid up there had been released.
