The report released on Jan. 9, showed the national diesel price average on Monday was $4.665 per gallon, down 2.2 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.

Most regions saw falling prices, with a 4.8-cent drop in New England being the largest.

The Rocky Mountain, West Coast and West Coast less California regions all reported a decline of between 4 and 5 cents.

With a 6.2-cent increase, the Gulf Coast experienced the biggest change in its average price from last week. The Lower Atlantic also reported an increase, by almost 3 cents.

The Gulf Coast region reported the lowest average diesel price per gallon ($4.228) of any region this week.
