How much money do we taxpayers spend on Bush's gasoline?

Got this some a friend; if someone can cite the source, please feel free to do so. Very thought-provoking nonetheless:

Presidential motorcade
Typically has well over a dozen vehicles
Includes president’s limousine and identical decoy limo.
Often idles outside presidential events for quick departure.
Bush uses 2006 Cadillac DTS limos. Public version has 18-gallon tank and gets 18 miles-per-gallon city, 27 highway. A fill-up would cost about $47 dollars at national average of $2.61 a gallon. The presidential version is heavier, less fuel-efficient.
Sometimes Chevrolet Suburbans are used in place of limos. Public version has 31-gallon tank, gets 15 miles-per-gallon city, 19 highway.
White House won’t say what gas costs at special facility it uses.

At the ranch
Bush drives a 2001 white Ford F250 pickup.
1999 four-wheel-drive model gets 13 miles-per-gallon city, 17 highway.
A fill-up would cost at least $75 at $2.61 a gallon.

Air Force One
Usually a Boeing 747-200B with anti-missile system and other special features.
Air Force says fuel costs are $6,029 per hour.
Fuel cost per hour is up from $3,974 an hour in fiscal 2004.

Bush's travels
Bush has visited 46 countries during his presidency, some several times.
He’s been to all the states except Vermont and Rhode Island.
So far this year, he has made 73 domestic and foreign trips.
