Graybeard is right: Here in North Pole, and the Fairbanks area, all of the gas is refined at the only refinery in North Pole. We have Tesoro, Texaco, Chevron, Sourdough, and one other brand. They all get their gas from the Flint Hills refinery. And I'm sure the stations in the lower 48 do the same thing, that is buy their gas from the nearest refinery. Cuts down on shipping cost. By the way what is the price of gas down south? Just gassed up my trucks today and paid $2.899 for unleaded reguler, and $2.939 for diesel. It's funny how the oil is taken from the pipeline here in North Pole and refined, then trucked to the station two miles away. There it sells for more than they sell it in Anchorage after trucking it 400 miles.
