The average price of a gallon of self-serve regular gasoline in San Diego County rose today to its highest amount since May 21 of last year, increasing 2.6 cents to $4.113.
The average price has risen for 28 consecutive days and is 20.3 cents more than one week ago, 37.5 cents higher than a month ago and 53.6 cents more than a year ago, according to figures from the AAA and Oil Price Information Service.
The average price has risen 35.6 cents over the past 28 days, including 1.6 cents on Tuesday.
Analysts have cited increasing oil prices and the closure of some California refineries for maintenance as reasons for the rising gasoline prices.
Crude oil costs account for two-thirds to three-quarters of the price of a gallon of gasoline, according to Tupper Hull of the Western States Petroleum Association, a trade association representing oil companies in six western states.
