Is the shit. My car has 98k on it and it runs like new. You can't even tell it's running while idling. I think drinking it might flush out all of the "nasty" stuff that is making me sick.
its a vibrant shade of green glass made in pressed borosticks. Downside, you use it on an internal encasement, said piece will explode like a Liberian stuck in downtown Tel Aviv
I am going to have to look for that. We have some other stuff that sounds pretty similar, but I dont think I have seen the seafoam. Would be a perfect addition to my 150k + Civic.
Look at some Honda forums. I think that is were my bf read about it for his Honda. http://www.honda-tech.com/zerothread?id=755765
Oh, I dunno if it is in that thread or not, but some say not to use it on cars with over 100k. They claim that it eats all the crud and crud is what holds things together if there is a crack and it may cause the car to leak. I used it anyway. It thins out your oil, so you should change it shortly after.
I have used 'Lucas Oil Additive' it is like gorilla snot. It doesnt thin out anything, but it is a synthetic blend, they usually have the little gears display where one side is conventional motor oil and one is the lucas blend. Just shows how it stays on the parts even after they quit moving. Is very nice.
