U.S. drivers are paying nearly 10 cents more per gallon at the pump than they did two weeks ago, as worries about Ukraine contributed to a jump in the cost of ethanol used in making gasoline, according to a survey released on Sunday.
The Lundberg survey said the national average price of self-serve, regular-grade gasoline was $3.5098 per gallon on March 7, up 9.87 cents from two weeks earlier, and up 21.54 cents, or 6.5 percent, in just the last four weeks.
Diesel fuel prices also rose, increasing by 2.58 cents from two weeks earlier to an average $4.0323 per gallon.
