It was the second national decline in a row since a mid-August peak, according to a survey released Sunday.

The national average for self-serve regular stood at approximately $2.65 on Sept. 8, down from about $2.87, according to the Lundberg Survey of 7,000 gas stations across the country.

That was about 35 cents less than last year at this time.

Mid-grade prices averaged $2.77 a gallon, while premium cost $2.87.

Sunday's average for unleaded regular in Utah was $2.95, according to the AAA Utah Web site. That reflects only a one-cent drop from the statewide average on Aug. 10.
