Well, I was fortunate enough to do the Sales & Marketing VP of SeaFoam's Mortgage in Minneapolis last year. He introduced me to the man who invented it and the owner. GREAT people!!! I have used it for years and strongly recommend it. From old put up outboards that have been sitting around and you can get running, but can't get cleaned out and running smootly, just sit there and burn it out. Smokes like crazy, but that stuff works! I always put a little in my car, lawn mower, jetski's and boat gas. It is as Beetlespin said, a little bit of insurance knowing you are getting out all the "junk". It basically gets out all water and condensation. It has no chemical additives or harmful ingredients, it's made from oil, same thing gas is made from, is what I was told. Either way, I've winterized a motor or five for years. Works really well for me. I guess if people in the midwest and Canada use it that says a lot. Really tough conditions....
