Ultra Low Sulfur Diesel (ULSD) Fuel

In 2006, the EPA mandated that refiners transition to nationwide delivery of Ultra Low Sulfur Diesel (ULSD) fuel. ULSD contains less than 15 ppm sulfur and allows emissions on 2007 and newer diesel engines to be the most environmentally friendly engines ever produced. While emissions are greatly reduced, ULSD ushers in newer operational challenges for the diesel engine operator. These challenges include accelerated wear rates on fuel injectors and pumps requiring the use of Slickdiesel® Lubricator technology. The poor cold temperature operability of ULSD demands the more robust antigel chemistry of Diesel Fuel Supplement® + Cetane Boost®. Fuel injectors will foul more quickly — a problem easily solved by Diesel Kleen® +Cetane Boost®— and instability caused by long-term storage will necessitate the use of Clear-Diesel® Fuel & Tank Cleaner.
