The average U.S. price of regular-grade gasoline jumped 2 cents over the past two weeks, to $2.96 per gallon.
Industry analyst Trilby Lundberg of the Lundberg Survey says the increase came as crude oil costs also rose.
The price at the pump is $1.03 higher than it was a year ago. The average price of diesel is unchanged over the same period, at $3.13.
According to the Triple-A fuel survey the going rate across North Dakota is $2.78 a gallon. That comes to $1.69 one year ago. Minnesota comes in a few cents cheaper at just over $2.73.
