The national average price for a gallon of on-highway diesel did not change from the prior week in the week ended Monday, Oct. 21., remaining at $3.886, according to the Department of Energy’s Energy Information Administration. The ProMiles Fuel Surcharge Index, however, reported the national average price to be $3.828 in the week ended Oct. 21, down six-tenths of a cent from the prior week. ProMiles collects at-pump prices from thousands of truck stops nationwide.

The EIA also reported an unchanged week-to-week price in the week ended Sept. 9, which was the first since November 2010.
