Last week the average national price for a gallon of diesel received a slight 0.3-cent boost to $1.986 per gallon. This little bump is consistent with the U.S. Dept. of Energy’s anticipation of stable diesel prices over the next four to six weeks.

See DOE: diesel will remain high but stable.

Despite the increase in the national average diesel prices, many regions actually posted a decline, with New England posting the largest at 2.5 cents to $2.197. That region was also most in need of a price break, as it remains the most expensive region to fill up.

However, the West Coast and California regions are not far behind after more dramatic price hikes, at 7.7 cents and 5.2 cents to average $2.190 and $2.196, respectively. Bargain hunters may want to fill up in the Gulf Coast if possible, as it averaged $1.915 on a 2.3-cent slide.
