Data from EPA's ULSD pump survey from the Fourth Quarter of 2006 through the First Quarter of 2010 indicate that more than 99 percent of highway diesel fuel pumps are now dispensing Ultra Low Sulfur Diesel (ULSD) and that the sulfur content of the fuel is less than 7 parts per million (ppm).
BUT! THE real question is ...does the fuel show 8.4 before or after refining?
