National average diesel prices took a 0.2-cent dip last week to $1.869 per gallon. Although this is the second week in a row prices slipped, it still marks a thin 0.5-cent margin from the record high that was set two weeks ago.
The most dramatic decreases appeared in regions that needed it the most — with the West Coast shedding 1.3 cents to $2.038 per gallon. California, which once again was the most expensive region to buy diesel, saw a relatively steep 1.2-cent decrease.
The Lower Atlantic region is the cheapest to fill up, despite a 0.3-cent hike, at $1.818. The Rocky Mountain region tied Lower Atlantic for the steepest increase (0.3 cents), at $1.918.
