SAN DIEGO - The average price of a gallon of self-serve regular gasoline in San Diego County rose Wednesday to its highest amount since Nov. 1, increasing 3.7 cents to $4.055.
The average price has increased 11 of the past 12 days, rising 34.4 cents over that span, including 2.3 cents on Tuesday, according to figures from the AAA and Oil Price Information Service.
The average price is 26.9 cents more than one week ago, 40.5 cents higher than one month ago and 26.1 cents greater than one year ago.
The San Diego County average price is the third highest in the state, behind Los Angeles County ($4.058) and Ventura County ($4.057).
The price hikes result from high oil prices, Middle East tension, California refinery maintenance issues resulting in reduced supplies, and investors shifting their money into the gasoline market "earlier and earlier," according to Jeffrey Spring of the Automobile Club of Southern California.
