The average price of a gallon of self-serve regular gasoline in Riverside County rose three-tenths of a cent Saturday to $4.132.
The average price is one-tenth of a cent more than one week ago, 4.7 cents less than one month ago and 22.8 cents less than one year ago, according to figures from the AAA and Oil Price Information Service.
It has dropped $2.241 since rising to a record $6.373 on Oct. 5, 2022.
“Oil Price Information Service reports that Los Angeles wholesale gasoline prices are moving up as part of the annual cycle of switching from producing winter-blend fuel to the more expensive summer-blend gasoline,” Doug Shupe, the Automobile Club of Southern California’s corporate communications manager, said in a statement.
“This switch is required by California air quality regulations. Even though gas stations don’t have to start selling summer blend gasoline until April 1, refineries must adjust ahead of time to begin producing the summer blend.”
The national average price remained the same at $2.862. It is 3.2 cents more than one week ago and eight-tenths of a cent more than one month ago, but 27.1 cents less than one year ago. It has dropped $2.154 since rising to a record $5.016 on June 14, 2022.
