Diesel fuel indexes both show a weekly price increase of more than 4 cents

Despite differences last week, two diesel fuel indexes were in agreement on Monday, Oct. 1. Diesel increased by 4.2 cents on one and 4.3 cents on another.

However, mileage-tracking software company ProMiles reported the U.S. average being more than 4 cents higher.

AAA reports prices on Monday for diesel nearly 3 cents higher than last Monday.

On Monday, the EIA reported the U.S. average price per gallon of diesel cost $3.313.

The average price per gallon for diesel fuel is 52.1 cents higher than a year ago, according to EIA data.

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

• U.S. – $3.313, up 4.2 cents.
• East Coast – $3.292, up 3.8 cents.

ProMiles reports national average retail price for diesel on Monday went up 4.3 cents from the week previous. The average New England price was two-tenths of a cent lower than a week before, the only regional decrease.

The largest decrease was in the Midwest region, up nearly 6 cents.

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.

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

• U.S. – $3.241, up 4.3 cents
• East Coast – $3.269, up 2.8 cents
• New England – $3.251, down two-tenths of a cent
• Central Atlantic – $3.459, up 2.7 cents
• Lower Atlantic – $3.164, up 2.4 cents
• Midwest – $3.232, up 5.8 cents
• Gulf Coast – $3.096, up 3.1 cents
• Rocky Mountain – $3.356, up six-tenths of a cent
• West Coast – $3.669, up 4.8 cents
• West Coast less California, $341, up 3 cents
• California, $4.002, up 2.5 cents.
