Sea-Foam actually works, but mostly as a fuel stabilizer. I use it in all the small engines around the farm that only get run intermittently, and in the motorcycles my son and I run. It prevents at least most of the alcohol-additive nightmares untreated gasoline causes, especially in engines that get stored over the winter. Like any other fuel or oil additive, it's not a cure-all, but it seems to work well for its primary purpose of keeping gasoline from going stale.
