Funny how that works.

there is a reason for it... if prices are falling, there is no incentive to refill intermediate storage tanks because it will be cheaper to buy them tomorrow, but if prices are rising, they always keep the intermediate tanks full. Since the storage tanks aren’t taking in new gasoline at a lower price, the cost basis of the tank doesn’t fall as quickly, but the cost basis in a rising tank changes quickly.
