The retail price of gasoline has remained steady across the U.S. during the last three weeks despite falling crude oil prices and lower winter demand, according to the Lundberg Survey of 7,500 gas stations.

As of Feb. 9, the average price of gasoline nationwide was $1.52 a gallon, down 0.07 cents from Jan. 19, according to the Lundberg Survey.

Slight price increases along the West Coast and in the Rocky Mountain states offset the price decrease of nearly 1 cent per gallon in the remainder of the country.

Gas prices now average nearly 19 cents a gallon lower than last June, when the average price reached more than $1.71 a gallon.

Gas prices should remain steady or slip lower unless there are problems in the refinery or distribution systems, said industry analyst Trilby Lundberg.

The national average for self-serve regular unleaded gasoline as of Feb. 9 was $1.49 a gallon, including taxes. At full-service pumps, regular unleaded sold for an average of $1.86 a gallon.

Regular unleaded accounts for 98% of all gasoline sold.
