I wanted to put the word out that there is something out there that can save the owner operator from high fuel cost.  I found a company called Vehicle Fuel Conversions in Jacksonville, Fl who did something really spectular for me. They sell something called an HHO gas injection system. It makes hydrogen gas while you drive and injects it into the air intake of the diesel engine. I have run with this product for nearly 4 months and have averaged cutting my fuel bill by around a thousand dollars per month.
