For the first time in seven weeks, diesel prices across the U.S slipped, barely, according to data tracked by the Energy Information Administration (EIA).
The EIA said the average U.S. retail pump price for diesel was down a half-cent this week to $2.914 per gallon, which is $1.01 per gallon cheaper compared to the same week in 2014.
Diesel prices decreased in most regions of the country, though changes were only more than a penny or so only in California, where the price fell 2 cents to $3,249; and in the Central Atlantic, where the price fell 1.9 cents to $3.143.
The Midwest (up 0.4 cents to $2.804) and the Rocky Mountain region (up 0.5 cents to $2.835) posted the only gains.
The Gulf Coast (down 0.4 cents, $2.799) region continues to post the lowest cost for a gallon.
