A few regions saw an increase in fuel prices for the first time in several weeks, but most were down including the national average price per gallon of diesel. ProMiles.com showed a national fuel average of $3.929 on its Dec. 25 report. That is a 5-cent decrease from the previous week’s 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 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.

California had the largest decline of any region (11.1 cents), while the West Coast region was also down by 11 cents. The West Coast without California region dropped by 9 cents, the Midwest declined by 7.7 cents and the Rocky Mountain saw its average fuel price fall by 5.5 cents.

Increases were reported in the Lower Atlantic, East Coast and Gulf Coast. Of those increases, only the Lower Atlantic was more than 1 cent.

According to ProMiles, the highest fuel price per gallon is $5.315 (California) and the lowest is $3.582 (Gulf Coast).

Four regions have an average price less than $4 per gallon.
