If all you were buying was oil, and the price dropped $20 a barrel today over yesterday's price, that's the price you would pay. But once the oil enters the refinery and begins being transformed in to gas, diesel,heating oil, jet fuel, and a million other products, the price you pay will be for a finished product. And when the price of oil drops, and stays stable for a few month's, you notice the price of all those products I mentioned will drop also. So if the price of oil starts off high, everything associated with it will also be high.,
