Decided to suck sea foam through the pcv in my 175K Toyota Tacoma. Overall impressions are positive. During its life it's seen nothing but top tier gas and fuel system cleaners. Lots of smoke during the process. Took about a block to get rid of the smoke.
I use seafoam and it made a huge difference in the idle quality and snap throttle test on my 98 ford ranger. I like seafoam. I have not had a bad experience yet but it will work better on some vehicles than others.

A brand new car will smoke if you run seafoam through a vac line, it is just the pale oil burning off creating a smoke show, which many think that it is cleaning.
If you look at what it is made from, you are paying a ton of money for a very basic composition you could make at home in a large quantity very cheaply.
Does it have some cleaning ability as a fuel additive? Yes. Is it as good as something containing PEA detergents? Nope.
I've settled on Gumout Multi System Tuneup after trying numerous fuel treatments. That provides an improvement that I can actually see such as better startup and a smoother idle.
