The average price of a gallon of self-serve regular gasoline in the Inland Empire rose one-tenth of a cent Friday to $2.937, a day after falling two-tenths of a cent.
The average price in Riverside and San Bernardino counties is 1.3 cents less than a week ago and 6.1 cents less than a month ago, but 92.9 cents more than at this time last year and $1.135 more than at the start of the year, according to figures from the AAA and Oil Price Information Service.
"Gas prices have become very predictable this year, unlike any other year in this decade,'' said Jeffrey Spring of the Automobile Club of Southern California.
