Diesel prices fell for the fourth straight week, according to the U.S. Department of Energy’s Energy Information Administration.

The last time diesel prices dropped for four straight weeks was between mid-August through early September 2010, although those decreases were much smaller than the current streak.

The average price of diesel declined in all regions, ranging from a 4-cent dip in New England and the West Coast to an 8.1-cent drop in Rocky Mountain states.
