This week’s report shows diesel prices broke a streak of four consecutive weeks of decline, but just barely.

According to ProMiles, the national average increased by one-tenth of a cent per gallon of diesel and is now $4.438.

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. Like ProMiles, EIA gives the average price of diesel for the previous week.

Contrary to the national average, most regions were down, including by 8.6 cents in the California region and by more than 6 cents each in the West Coast without California and West Coast regions.

Five other regions also reported a decline, with the only increases coming in the Midwest (3.6 cents) and Rocky Mountain (1.9 cents) regions.

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

The most expensive gallon of diesel was $6.191 in California.
