San Diego County average gas price rises for 21st time in 22 days

SAN DIEGO (CNS) - The average price of a gallon of self-serve regular gasoline in San Diego County rose today for the 21st time in the past 22 days,

increasing nine-tenths of a cent to $3.437, its highest amount since March 13.

The average price has risen 16 cents over the past 22 days, including one-tenth of a cent on Monday, according to figures from the AAA and Oil Price

Information Service. It is 5.3 cents more than one week ago and 20.6 cents higher than one month ago, but 12.5 cents less than one year ago.

The rising prices are the result of some refinery trouble, the impending switch to summer-blend gasoline and the lifting of the state's stay-

at-home orders that increased demand, according to Jeffrey Spring, the Automobile Club of Southern California's corporate communications manager.
