Gasoline is piped through a few pipelines, and the pipelines are used by several different distributors/retailers. The additives are what is different, and they are added at the stations when it is delivered to their underground tanks. So the cheaper gasoline might not have or have cheaper additives if that means anything. That being said, gasoline is cheaper in the south in general, one because they are closer to the Texas refineries, and two their highway taxes are lower. In the north, you have union highway workers, and you have snow, colder climate, and the constant freezing and thawing does more damage to the highways thus requiring more maintenance. A study was done recently that said the number one highways in America were in Georgia, and the number two was in Alabama. My stepson lives in Illinois and believe me, the highways up there are worse than in Alabama and the gasoline is much higher. I try to fill up in Kentucky before crossing into Illinois when we go up. Prices won't come down and stay down until we get a different president and different policies.
