In any case, until there is a new refinery, the margin stays as high as possible. The fact that there are no new players to increase the number of refineries and create a surplus is a lot more profitable for you. As long as there is a shortage of supply, the price can be kept high and blamed on demand. That is the best explanation that you can give us today. With new refineries, there would be a surplus, and gasoline would simply cost less.
