Diesel price per gallon changes a mixed bag around the country

In terms of the national average, diesel is more expensive again this week up to $4.449 per gallon. However, certain regions are now paying less per gallon, according to the latest ProMiles.com report.

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.

The largest increases came in the West, including the West Coast region (13.5 cents); California region (12.7 cents); and West Coast without California region (8.7 cents). In addition, a 5.1-cent increase was reported in the Rocky Mountain region.

As far as the national average, the ProMiles report said it’s up by just under 2 cents.

Down by between 1 and 2 cents per gallon were the Lower Atlantic and East Coast regions.

With a price per gallon of $4.109, the Gulf Coast region reported the lowest average of any region this week.
