The national average retail price of a gallon of diesel fell 1.8 cents to $2.799 during the week ending Monday, June 4, according to the U.S. Department of Energy. That price is 9.1 cents cheaper than the same week in 2006.
Diesel prices fell in every region tracked by DOE, led by the Gulf Coast, where prices fell 2.7 cents to $2.749 to become the nation’s cheapest diesel; the New England region saw the smallest decrease, just over half a cent. Among regions tracked by DOE, the Rocky Mountains had the most expensive diesel in the country, at $2.958 per gallon. Truckers in California, which DOE tracks separately, paid even more, $2.972.
