The average price of a gallon of self-serve unleaded regular gasoline again rose in San Diego County Tuesday, but the steady increase continued to show signs of moderating, according to figures from AAA and the Oil Price Information Service.
The price rose seven-tenths of a cent to $2.222. It increased 2.3 cents Friday, 1.7 cents Saturday, 1 cent Sunday and eight-tenths of a cent Monday.
The average price is 10.7 cents more than last week and 24.5 cents more than a month ago, but 88.1 cents less than at this time last year and $2.408 less than the record high of $4.63 set on June 19.
The increase is the result of reduced supply, caused in part by lower production at the state's refineries, according to Jeffrey Spring of the Automobile Club of Southern California.
The national average price of a gallon of unleaded self-serve regular gasoline rose four-tenths of a cent today to $1.928, a day after increasing by three-tenths of a cent. The average is 3.8 cents more than a week ago and 13.6 cents more than last month, but $1.025 less than this time last year and $2.186 less than the record high of $4.114 set July 17.
California's gasoline prices are typically higher than the national average and among the highest in the nation because of taxes and a state law mandating a special blend of fuel to reduce polluting emissions.
