LOS ANGELES -- California gas prices will increase for several more days before leveling off after a temporary reduction in supply triggered a price spike that saw fuming motorists paying $5 or more per gallon in some locations and station owners shutting down pumps in others.

The Golden State leapfrogged Hawaii as the state with the most expensive fuel. The average price for a gallon of regular unleaded across California was nearly $4.49 on Friday, 32 cents more than a week ago and the highest statewide average in the nation, according to AAA's Daily Fuel Gauge report.
