i'm new here, this is my first input to the site, making my own fuel for my f250, used oils and diesel blend, i also designed my own HHO system, they both work. i know not every one believes in simple way's of doing things,oh well. but the "KISS" program does work,(keep it simple stupid), i'm glad to see so many other people working on these types of alternative fuels. keep trucking! i just wish we could share with the country what we have done.
