The average price of gasoline has jumped by six cents over the past two weeks to $2.37 a gallon for regular grade.
Industry analyst Trilby Lundberg said Sunday that the hike is mostly due to a continuing increase in crude oil prices. The price at the pump has risen 60 cents over the past 15 weeks.
In the Lower 48, the highest average price of regular gasoline was $2.87 per gallon in San Francisco. The lowest was $2.04 in Tulsa, Oklahoma.
