you arrive at approximately 3.5 million gallons of oil: the daily petroleum tab for U.S. combat operations in the Middle East war zone.

Let's see, 85 million bbls.day worldwide, and 3.5 million gallons day / 55 gallons/bbl. = 63,600 barrels/day for the wars.

63,600 divided into 85,000,000.  It's actually a rather small percentage of global oil consumption totals.  But it is close to 0.1%, which is pretty big as a percentage if we count it all as the consumption total of a single corporate consumer.
