The Orange County average price is 26.1 cents more than one week ago, 37.9 cents higher than one month ago and 22.2 cents greater than one year ago.
The increasing prices are the result of higher oil prices, Middle East tensions, maintenance issues at refineries and investors shifting their money into the gasoline market "earlier and earlier," according to Jeffrey Spring of the Automobile Club of Southern California.
