Diesel fuel costs held steady for the week ending June 5, but did rise by about a penny in several regions of the country.

The Energy Information Administration reported that the national average rose less than 1 cent to $2.890 per gallon. That price is still more than 65 cents higher than the average for the same week in 2005.

The biggest increase was in the Midwest, where the average rose by less than 2 cents to $2.837. On its heels was the East Coast’s Lower Atlantic region, which went up exactly 1 cent to $2.825.

Other East Coast regions rose slightly, with New England and the Central Atlantic rising to $2.969 and $2.992, respectively. The East Coast as a whole averaged $2.881 per gallon, an increase of less than a cent.

California posted the highest average, where prices held steady at $3.227 per gallon. The rest of the West Coast remained close behind, dropping by less than a penny to $3.159 per gallon.

The Rocky Mountain region remained above the $3 mark for the sixth week in a row, but fell a fraction of a cent to $3.043 per gallon.

The Gulf Coast, meanwhile, posted the lowest average at $2.805 per gallon, an increase of less than a cent.
