At (my) last count there were ninety-two different seasonal and regional blends that our refineries have to produce. Every year, twice a year, refineries have to schedule shutdowns to convert the equipment for the upcoming seasonal blend.
Let any unforseen circumstance arise, such as an unscheduled outage at another refinery, a pipeline failure, or two-percent of the global oil supply being taken off the market, and you can see a shortage within days.
Right now the price of crude is sliding back and more refineries are completing their seasonal change-over. You will see some relief at the pump. When you consider tax-crazy politicians, crazy global leaders, ever-increasing global consumption, and the unknown variables I mentioned above, however, it may not be a big drop and it might not last long.
