California is leading the nation again this week with the sharpest price increase at the gas pump. Many pumps increased by 20 cents a gallon pushing the state average to 4.01, the statea s highest since July of 2014, and a 60 cent jumo in just the last month. Experts at triple A say planned and unplanned maintenance at Californiaa s refineries is the major cause. Motorists however, facing sticker shock at the pump, question the timing with great weather and the Easter weekend coming up.
