What most people don't understand is that the largest supply of gasoline in the U.S. -- by a very wide margin -- is the combined fuel that is "stored" in the gas tanks of all our vehicles.
How do you figure that? The latest inventory number for gasoline was 194.4 mbl or 8.165 billion gallons. How many cars are there? 120 million? times 20 gallons? 2.4 billion gallons.
