The report released on March 13, showed the national diesel price average on Monday was $4.382 per gallon, down 1.8 cents from last week.

ProMiles produces a report that is similar to one published weekly by the federal Energy Information Administration. A key difference between the two reports is the type and number of fueling stations in order to calculate its averages. While ProMiles uses its direct feed from thousands of truck stops to develop its averages, EIA surveys 400 truck stops and convenience stores nationwide. The EIA report is also the average price of diesel for the previous week.

The Gulf Coast was the only region to report an increase (2.5 cents), but it still has the lowest average price per gallon of any region this week.

Of the nine regions reporting a decrease, New England’s was the most significant at 11.5 cents.

Down 8.5 cents was the Central Atlantic region. The East Coast and Rocky Mountain regions saw a drop of 6.4 cents each.
