I use Seafoam in my diesel engines year round, along with an anti gel treatment in winter. I don't use it for every tank because I keep clean fuel in them, but I have had to let one sit for a long period in the past and when I finally got to run it, I added Seafoam and I could hear the engine running better and better as I ran it. Most guys who says it doesn't work do so without ever having tried it. Go to the lawn care forums and ask the guys there if it works (or tell them it doesn't). It work wells in both diesel and gasser ZTR's.
It doesn't work as an anti gel substance, but it definitely helps clean injectors and the fuel delivery system, especially if your machine has been sitting for some time with fuel in it. I've witnessed it first hand many times on different engines.
