Whether or not seafoam works (I used to use it), I will say that this video is pretty lame and doesn't prove anything other than the point that [Not all of the smoke coming out of the tailpipe while seafoaming is carbon]. I don't think anyone would argue that. Seafoam is also advertised as having other benefits (like cleaning the fuel system) which he doesn't test.
I think what he'd have to do is have a two engines that are brand new and identical, run them both for a while. Seafoam one of them, and then dismantle the engines, scrape out all the carbon deposits and weigh them.
Seafoam truly might not be doing anything, but his video sucks as proof.
