The average price of a gallon of self-serve regular gasoline in Riverside County rose three-tenths of a cent Sunday to $4.316, its third consecutive increase.
The average price is 1.4 cents higher than one week ago, 2.6 cents more than one month ago and $1.143 greater than a year ago, according to figures from the AAA and Oil Price Information Service. It has risen $1.14 since the start of the year.
The average price rose one-tenth of a cent Saturday and three-tenths of a cent Friday.
The average price could increase in connection with rising crude oil prices prompted by Hurricane Ida. The price of a barrel of West Texas intermediate crude closed at $68.74 Friday on the New York Mercantile Exchange, up $1.32. It closed at $65.46 Aug. 18.
Crude oil costs account for slightly more than half of the pump price, according to the U.S. Energy Information Administration.
