ProMiles.com reports the average U.S. retail price per gallon for diesel increased by 1.7 cents to $3.314, according to a Sept. 27 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.

All but two regions show increased prices this week. The largest increase came in the Lower Atlantic (2.8 cents), while the East Coast, Central Atlantic and Midwest also reported an increase of more than 2 cents.
