The Dec. 27 data release said the national average price per gallon of diesel is now $3.615, down from $3.626 last week. That average is 98 cents higher than it was one year ago.

A 2.7-cent drop in the Rocky Mountain region was the largest decline this week, while the West Coast less California also reported a drop of more than 2 cents.

The only region where prices were higher (California) saw an increase of three-tenths of a cent. California also has the highest average price per gallon, at $4.771.

$3.33 is the lowest average price per gallon, and that is in the Gulf Coast.

ProMiles.com reports the average U.S. retail price per gallon for diesel decreased by 2.2 cents to $3.508, according to a Dec. 27 report.

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.

Prices from coast to coast dropped again this week, according to the ProMiles report. The largest drop came in the Rocky Mountain region, with a 3.3-cent decrease. The West Coast less California region wasn’t far behind, reporting a 3.1-cent drop.

At $3.295, the Gulf Coast remains home to the lowest average price per gallon in the nation.
