The average price of a gallon of self-serve regular gasoline in Riverside County rose for the 12th consecutive day Sunday, increasing eight-tenths of a cent to $5.62.
The average price has risen 10 cents over the past 12 days, including 1.9 cents Saturday, according to figures from the AAA and Oil Price Information Service. It is 6.5 cents more than one week ago, 2.4 cents more than one month ago and $1.15 more than one year ago.
The average price has increased $1.069 since the start of the joint U.S./Israel attack on Iran on Feb. 28, which sent oil prices higher and drastically accelerated increases at the gas pump.
The national average price dropped three-tenths of a cent to $4.078. It is 2 cents less than one week ago and 2 cents less than one month ago, but 88.6 cents more than one year ago.
The national average price has increased $1.096 since the attack on Iran. It is at its highest amount this late in the calendar year, according to Patrick De Haan, head of petroleum analysis at GasBuddy, which provides real-time gas price information from more than 150,000 stations.
