The average cost of diesel in the U.S. stayed nearly flat for the second week in a row, rising three-hundredth of a cent in the week ending Sept. 17 as oil prices fell.
The average cost per gallon, $4.135, is up 30.2 cents from the same period a year ago, according to the U.S. Energy Information Administration. Prices, which have increased in the last 11 weeks, rose across the country except on the West Coast. The average price remains above the $4 mark in all regions.
Crude oil for October delivery dropped $2.38, or 2.04 percent, to $96.62 a barrel on the New York Mercantile Exchange, according to MarketWatch. Prices fell on speculation the United States would tap the Strategic Petroleum Reserve.
