Diesel fuel prices slide for the 19th straight week

ProMiles.com reports the average price for diesel fuel in the U.S. on Monday, May 18, dropped 1 cent from the Monday before.

ProMiles, the software company that maintains the websites ProMiles.com and TruckMiles.com, offers its own weekly fuel price information. The company’s fuel price data are presented in the same format used by the EIA in the agency’s weekly reports. The prices include a national average as well as regional averages, and comparisons to the previous week and the previous year.

A key difference between the EIA and ProMiles reporting is the type and number of fueling stations the company surveys in order to calculate its averages. While EIA surveys 400 truck stops and convenience stores nationwide, ProMiles uses its direct feed from thousands of truck stops to develop its averages.

The U.S. average diesel fuel price is 80 cents less than one year ago, according to ProMiles.com.
