After four straight weeks of small decreases, the national retail price of on-highway diesel rose 1.2 cents to $2.943 per gallon during the week ending Monday, Sept. 13. The price of diesel is 30.9 cents higher than the same week last year, according to the U.S. Department of Energy’s Energy Information Administration.
Diesel prices increased in all but three regions: New England, West Coast and California. The nationwide rise in prices was due to a 2-cent increase in the Midwest — the only region where the average price increase was higher than the 1.2-cent overall increase.
As usual, prices were highest in California at $3.142 a gallon, followed by $3.101 in other West Coast states. The nation’s least expensive diesel by region, $2.887, was found in the Gulf Coast region.
Average retail prices for all regions are available on EIA’s website.
