Fuel:
The Airbus A380–800 can carry 320,000 of fuel, spread out in its wings and horizontal tail. The A380 is somewhat unique amongst large jets in that it does not have a center fuel tank. Had Airbus built the A380–900, this aircraft would have incorporated a center fuel tank, and that tank would have been enormous.

Is the A380 efficient?
It was. Typical mission: 545 pax, 320,000 litres of fuel, 15,000 km flight: 3.9L/100pax.km.
The A380 is less efficient than the 777–300ER — and aircraft from the same era, and much less efficient than the 787, and the A350.
