Ultra Low Sulfur Diesel (ULSD) fuel and new engines and vehicles with advanced emissions control systems offer significant air quality improvement.
Highway ULSD Fuel
EPA standards have led to a major reduction in the sulfur
content of diesel fuels. Highway Diesel
New Diesel Technology
Ultra Low Sulfur Diesel (ULSD)
is a cleaner-burning diesel fuel
containing a maximum 15 parts-
per-million (ppm) sulfur. Vehicle Performance
Non-Road ULSD Fuel
New EPA fuel standards for
diesel fuel also apply to
locomotive, marine and non-
road engines and equipment,
such as farm or construction
equipment. Non-Road Diesel
Environmental Benefits
ULSD fuel along with new
engine and emission control
system technologies have
an important role in improving
air quality and providing human
health benefits by significantly
reducing current emissions. Environment and Health
