Excellent product. Don’t overuse it. It will eat seals and gaskets if overused. A lot of fuel cleaners marketed under different names are naptha or similar compounds. Most are pretty much the same chemicals.
I sed it in my transmission. It didn’t help the transmission because it was worn out. It did, though, clean our the return lines of the gunk that kept the holes from leaking. I replaced the lines. I would say it is good stuff.

No wonder boaters like it. Those seals can be a PITA.
Instead of SeaFoam why didn’t they call it PolarBear?
When I was a kid playing with model airplanes, I remember the MEK my brother brought home from work smelled like lacquer thinner, but it cleaned my brushes WAY quicker and dried my hands out much more.
