ProMiles.com reports the average U.S. retail price per gallon for diesel decreased by 6.9 cents to $4.939, according to a Sept. 26 report.

A key difference between the EIA and ProMiles reporting is the type and number of fueling stations the company surveys in order to calculate its averages. While EIA surveys 400 truck stops and convenience stores nationwide, ProMiles uses its direct feed from thousands of truck stops to develop its averages.

Every region was down, and by as much as 9.5 cents in the New England region.

The Midwest saw its price drop by 8.6 cents, while the Gulf Coast and Central Atlantic were down 7.2 cents and 7 cents, respectively.
