Yeah, the cruising range doesn't actually mean on board fuel, since that doesn't jive with the "1,185 gallons of fuel oil per hour at routine usage" numbers you gave early.
It's a common issue on listed cruising ranges vs internal fuel, official numbers include in the range fuel from tankers accompanying the convoy, and/or refueling stops.
The Big Mo gets something like 4 yards to the gallon, and only carries 2.5M gallons of assorted fuel, yet its range is often listed as something like 17,250 miles (15k nm) at 17.25 mph (15 knots), instead of the 5,750 miles (5000 nm) it can actually make on internal tanks.
