ProMiles.com reports the average U.S. retail price per gallon for diesel increased by 1.9 cents to $3.244, according to a July 6 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.

Costs were higher in every region this week. The largest increase was 8.4 cents in the Rocky Mountain region up to $3.512, while the highest price per gallon is in the California region at $4.083.
The Gulf Coast price of $3.045 is the lowest per gallon in the nation.
