Diesel Fuel Properties
Diesel fuels are sampled from each region of the United States and analyzed using industry standard test methods. Typical diesel fuel properties reported are listed below. The surveys contain compilations of the physical and chemical properties of fuels marketed throughout the United States. The reports list trends of typical fuels and their selected properties over the last 15 years, and contain summary tables comparing current and previous year’s average, minimum and maximum values. The survey map shows the geographic boundaries of the regions sampled. Fuel supplier names have been removed to enable publication of these data.
