The seasonal transition to winter-blend gasoline, which is cheaper to produce, is also beginning. While the national average has been relatively stable, drivers in the Pacific Northwest are feeling pain at the pump. Gas prices in the area have jumped more than 20 cents in the past week due to the shutdown of a major pipeline that transports fuel from Washington to Oregon. The pipeline is reportedly expected to resume operations in a few days.”
