Did anyone see the thing on the discovery channel the other night? It was about gas. It was saying that most of the gas we get is pumped through pipelines from the refineries to bulk holding tanks. All the oil companies put gas in them and take gas out of the other end the same day. They went on to say that it takes a few days for the actual barrels that were put in to reach the other end. They also said all the gas is the same, you dont really know whos gas you are getting. The only difference is the additives that go into it when it is loaded into the trucks to be distributed to the stations.
