ProMiles says diesel up as much as 18 cents

A significant surge in diesel prices was reported this week, particularly in the West, where prices were up by at least 15 cents according to this week’s ProMiles.com report, with the national average hitting $4.445.

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 used to calculate 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 also gives the average price of diesel for the previous week.

The regions with the highest increase from a week ago included the West Coast without California (18.9 cents), California (16.1 cents), Rocky Mountain (16 cents) and West Coast (15.2 cents).

A 10-cent increase was reported in the Midwest, while the Lower Atlantic was up by just under 10 cents.

With a price per gallon of $4.124, the Gulf Coast region reported the lowest average of any region this week.
