For example, any dispenser with ULSD (S15) will state the fuel is required for use in all model year 2007 and later highway diesel vehicles and engines, also recommended for use in all diesel vehicles and engines. Any dispenser with S500 (500 ppm of sulfur) diesel fuel will state that the fuel is not suitable for fueling model year 2007 and later vehicles. • The following EPA website provides more details on the dispenser labeling requirements: http://ecfr.gpoaccess.gov WHAT IS THE CHEMICAL DIFFERENCE IN THE ULSD FUEL? There is no major chemical difference between current diesel fuels and ULSD. ULSD is just further processed to remove more sulfur. There are, however, certain fuel characteristics that may be affected: • LUBRICITY – Diesel fuel must adequately lubricate the fuel injection system components. The processing required t
