The report marks the second straight increase after seven consecutive declines, and leaves trucking’s main fuel 10.3 cents a gallon more expensive than a year ago.
Gas was unchanged from last week, remaining at $3.704, DOE’s Energy Information Administration said. The current price is 20.8 cents a gallon more expensive than a year ago.
