K 100 is great stuff. Made locally in Tonawanda. The original formula was designed for use in heating oil tanks for controlling water problems. It was later devil oped for gasoline use. Their motor is "we make water burn" . They are the real deal to the water problems, ethanol separation problems, as well as a fuel stabilizer. Over the years we have tried out its use in various surcumstances and it has prevallaled. Cleaning out clogged jets, stabilizING fuel, ridding water in bottoms of tanks. Preventing corrosion in tanks and lines! It can be had in a couple different formulas.
