I first heard of Star Tron at a web site (Mytractorforum).  I have an older Bolens tractors,a Green Machine trimmer and a Homelite chainsaw. I have been running treated gasoline in all of these engines. When I first used treated gass in the tractors I noticed some black soot when the engine was under load, but it cleared up when running the second tank of gas. The trimmer did not show the soot but did run much better with the treated gas mix. The chainsaw starts much easier even if it sits for a long time. As a hobby, I repair small engines on lawn mowers, trimmers, and chainsaws. I always put in some treated gas when repairing them. They start much better after running for a short while. I am also putting the Star Tron in the gas for our 55 Yahama outboard engine on a 24 foot pontoon. It runs much better and a lot cleaner.
