ProMiles.com reports the average U.S. retail price per gallon for diesel increased by 1.9 cents to $3.301, according to an Aug. 9 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.

Prices increased by 7.1 cents from last week in the California region, which was the largest increase nationally. The West Coast region saw an increase of nearly 6 cents and the West Coast less California region had a 4.7-cent surge.

The Gulf Coast continues to feature the lowest price per gallon, at $3.072, this week.

The U.S. average diesel price is 98.6 cents higher than one year ago, ProMiles.com reports.
