The average price of a gallon of gasoline in the U.S. has jumped 26 cents since prices bottomed out in January, according to a survey released Sunday, NBC News reported. Regular-grade gas rose to an average price of $2.33 per gallon, pushed higher by a steelworkers' strike and an explosion Wednesday at an Exxon Mobil Corp. refinery in Torrance, California, according to the biweekly Lundberg survey. But gas is still more than a dollar cheaper on average than it was at same time a year ago, and there's no shortage of gas, the survey's publisher said.
