For the third week running, diesel prices decrease across the U.S.

Diesel prices are indeed lower this week than last, and this repeats a pattern from the previous two weeks.

The average U.S. price of a gallon of on-highway diesel went down 3.6 cents per gallon from the week before, to $3.063 per gallon, for the week ending Monday, Feb. 19, according to the Energy Information Administration.

Average U.S. prices have decreased for three weeks. Like last week, prices went down in all regions.

The data for the EIA’s fuel price report comes from surveys of 400 truck stops and convenience stores nationwide.

The lower prices reported by the EIA are corroborated by data form ProMiles.

Land Line reported on Monday that according to ProMiles the average price of a gallon of on-highway diesel in the U.S. was down 4.4 cents per gallon from the week before, to $2.966 per gallon.

ProMiles, the software company that maintains the websites ProMiles.com and TruckMiles.com, presents its fuel price data in the same format as the EIA. However, ProMiles uses a direct feed from thousands of truck stops to develop its averages.
