"John Mullinix of Ledford has acquired a provisional patent on a fuel mixture he says will dramatically reduce the amount of noxious emissions from automotive engines. "The mixture is simple: One ounce of diesel fuel per 10 gallons of gasoline. "Mullinix has reports from John A. Logan College and Southern Illinois University on vehicles tested using his formula that indicate significant declines in hydrocarbons, carbon monoxide and nitrous oxide. "The study at SIU involved a Ford F-150 pickup truck. "Hydrocarbon emissions -- unburned fuel in the form of carbon soot responsible for smog -- after flowing through a catalytic converter tested at 21.700 parts per million with gasoline. That same gasoline with the 1 oz. of diesel added tested at 10.005 parts per million -- a 51 percent hydrocarbon emission reduction." A slight MPG increase is also noted. More here. Could it really be this simple to significantly reduce emissions of ALL the gas powered cars on the road? If this mixture really works, shouldn't the EPA require it's being put on the market immediately after further validation testing?
