A drop of another 1.7 cents brought the average price for a gallon of diesel fuel across the U.S. below $3, according to the weekly report issued for Monday, Aug. 19, by the Energy Information Administration.

The average U.S. diesel fuel price has decreased every week starting with the July 15 report. This is the sixth consecutive week of falling average diesel prices for the U.S., according to the EIA.

The U.S. average price last dipped below $3 per gallon in the Feb. 11 report.

The Gulf Coast region has the lowest average price for diesel, at $2.751 per gallon. California has the highest priced diesel.

Following are the average prices for diesel fuel by region as reported by the EIA for Monday:

  • U.S. – $2.994, down 1.7 cents.
  • East Coast – $3.019, down 1.5 cents.
  • New England – $3.048, down 2.5 cents.
  • Central Atlantic – $3.199, down 1.6 cents.
  • Lower Atlantic – $2.892, down 1.2 cents.
  • Midwest – $2.90, down 2.4 cents.
  • Gulf Coast – $2.751, down 1.2 cents.
  • Rocky Mountain – $2.939, down one-tenth of a cent.
  • West Coast – $3.564, down 1.6 cents.

The national average U.S. retail price for diesel fuel dropped 2.2 cents to $2.90 per gallon on Monday, Aug. 19, from a week ago, according to ProMiles.

ProMiles, the software company that maintains the websites ProMiles.com and TruckMiles.com, offers its own weekly fuel price information. The company’s fuel price data are presented in the same format used by the EIA in the agency’s weekly reports. The prices include a national average as well as regional averages, and comparisons to the previous week and the previous year.

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.

Decreases of 1.2 to 2.8 cents were recorded for all regions except the West Coast. There, the average price went up less than a penny, whether California was included or not.

The largest decreases were in California and New England, according to ProMiles.

Following are the average prices by region as reported by the ProMiles.com:

  • U.S. – $2.90, down 2.2 cents.
  • East Coast – $2.983, down 2.1 cents.
  • New England – $3.037, down 2.7 cents.
  • Central Atlantic – $3.19, down 2 cents.
  • Lower Atlantic – $2.867, down 2.5 cents.
