The average U.S. retail price of on-highway diesel fell 16.5 cents in the week ending November 9 to $6.127 a gallon, according to the Energy Information Administration's weekly Gasoline and Diesel Fuel Update released November 10.

The national average had stood at $6.352 on October 26 and $6.292 on November 2, making the latest reading the second consecutive weekly decline. Even after the drop, diesel remained $2.290 a gallon higher than a year earlier and $2.606 higher than two years earlier.

Every region tracked by the agency posted a decrease. The Rocky Mountain region recorded the largest weekly decline at 23.9 cents, bringing its average to $6.206, while the Midwest fell 20.1 cents to $6.201. The Gulf Coast average dropped 17.1 cents to $5.741, and the Lower Atlantic region, which includes Georgia and the Carolinas, slipped 12.0 cents to $5.694, the lowest regional price in the survey.

Prices remained highest on the West Coast, where diesel averaged $7.110, down 16.2 cents. California averaged $7.897 a gallon after a 17.9 cent decline. In the Northeast, the Central Atlantic region averaged $6.412 and New England $6.349, with weekly declines of 7.4 cents and 6.7 cents, respectively.

Retail gasoline followed a similar path, with the national regular grade average falling 15.8 cents to $3.995 a gallon. The EIA data show that diesel continued to carry a premium of more than $2 a gallon over gasoline nationally.

The agency's separate breakdown of August retail costs showed crude oil accounted for 37% of the $5.46 diesel price that month, with refining making up 40%. The next weekly survey is scheduled for November 17.
