New U.S. Environmental Protection Agency (EPA) standards require a major reduction in the sulfur content of diesel fuels and emission levels from diesel engines and vehicles. To meet the EPA standards, the petroleum industry is producing Ultra Low Sulfur Diesel (ULSD) fuel, a cleaner-burning diesel fuel containing a maximum 15 parts-per-million (ppm) sulfur.  

Like Low Sulfur Diesel fuel, ULSD fuel requires good lubricity and corrosion inhibitors to prevent unacceptable engine wear. MFA Oil is leading those efforts with PDF Ultra, our premium diesel fuel --specially formulated to increase lubricity and inhibit corrosion.
