Since refineries typically can only produce 19 - 20 gallons of gasoline per barrel (42gal) of crude oil it would take ~11.3 million barrels of crude oil to produce the 224 million gallons of gas.

It still doesn't look very good but I just thought I'd point that out.

Yes, this is the same point I was making, except I zeroed on the inaccuracy of equating the saving of gas at $4 per gallon to that of crude at $1.80 a gallon.

As you point out, a gallon of crude only delivers about half a gallon of gasoline, so even looking at it that way, you are saving the equivalent of 10 million barrels of crude.
