The average national price of a regular gallon of gasoline continues to drop.
Industry analyst Trilby Lundberg said Sunday that the price of a regular gallon of gas dropped 5 cents in the past three weeks to $2.45 a gallon.
Lundberg says the drop came despite a rise in crude-oil prices. She says retailers and refiners dropped prices to chase demand from U.S. drivers.
The Bay Area had the most expensive gas at $3.13 a gallon among cities surveyed in the lower 48 states. Charleston, S.C., had the cheapest at $2.10.
The average national price for midgrade gas was $2.66 and $2.83 for premium. Diesel dropped about 8 cents to $2.90.
The average price for a regular gallon of gas is down $1.16 from last year.
