The Lundberg Survey of fuel prices released Sunday says the price of a gallon of regular is $3.25. Midgrade costs an average of $3.44 a gallon, and premium is $3.59.
Industry analyst Trilby Lundberg said it's the first price hike since Sept. 6.
Of the cities surveyed in the Lower 48 states, the highest average, $3.58 a gallon, was found in San Diego. The lowest, $2.93, was in Tulsa, Okla.
