March 7, 2023

The report released on March 6, showed the national diesel price average on Monday was $4.40 per gallon, down 6.7 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.

Diesel prices continued a downward trend across the country, according to the latest ProMiles report.

The largest drop was 10.4 cents in the New England region.

Down by around 9 cents were the Lower Atlantic and East Coast regions. The Central Atlantic saw a decline of 7.5 cents, while the Midwest and Gulf Coasts were down by about 6 cents.

With a price per gallon of $3.964, the Gulf Coast region reported the lowest average of any region this week.
