Overview of Diesel Fuel Testing and Reporting
EPA’s diesel program standards require that:
- After 2010, all highway diesel fuel supplied to the market be Ultra Low Sulfur Diesel (ULSD) and all highway diesel vehicles must use ULSD; and
- After 2014, all nonroad, locomotive, and marine (NRLM) diesel fuel must be ULSD, and all NRLM engines and equipment must use this fuel (with some exceptions for older locomotive and marine engines).
