ULSD is a cleaner burning diesel fuel than others, comprising of a maximum of 15 parts-per-million (ppm) sulfur. Most of the highway diesel fuel created or imported into the U.S. will be ULSD fuel and replace Low Sulfur Diesel fuel containing a maximum of 500 ppm sulfur. In combination with cleaner-burning diesel engines and vehicles, ULSD fuel will help to improve air quality by significantly reducing emissions. Currently CITGO's refineries and facilities do not support the production of ULSD. Greater refining and manufacturing are required to produce ULSD as the amount of sulfur must be dramatically decreased.
