The Better Business Bureau of Minnesota and North Dakota (BBB) is warning of GMAX350, an alternative fuel system marketed by Gertken Enterprises, which is located in Sauk Centre, Minnesota. On their website (gmax350.net), the company claims people can “start using water for gas.” They have an F rating with the BBB due to a failure to provide requested substantiation of their advertising claims. When contacted by the BBB last year, the company owner declined to provide a response to the BBB’s inquiry.
