ProMiles, EIA reports show another week of diesel increases

National and regional diesel prices went up again this week, by as much as 20 cents for some regions. According to the latest ProMiles.com report, the national diesel average is now $4.516 after an increase of 6.7 cents.

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 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 also gives the average price of diesel for the previous week.

A surge of nearly 21 cents was reported in the California region, the largest of any region this week.

Significant increases also came in the West Coast region and West Coast without California region, which were up 16.1 cents and 11 cents, respectively.

The Gulf Coast region was also up by double digits but maintained the lowest average ($4.21) of any region this week.
