Emal, my apologies, you're right re the model #. The fuel burn was not only due to the different engine model - the A300 wing was significantly shorter than the B767s and wasn't as advanced a supercritical airfoil section. Also, the A300 had larger flap track canoes which increased the drag.
Wrt the JT9D powered B767-200, its fuel burn at domestic loads was about 4,500kgs per hour (in cruise) whereas the A300 was about 5,700kgs per hour. There was no doubt about it though, the CF6-80 was the better engine by a big margin.
Airbus designed the aircraft to be compatible with the B747 wrt cargo containers which is why you can get 2 LD3's side by side in the cargo hold. The B767 was designed by Boeing originally to be a fuel efficient trans-continental domestic aircraft so a slimmer twin aisle fuselage was deemed to be a better option despite the lack of compatibility with cargo containers. The efficiency, along with a lot of growth potential in the original design allowed it to grow into an intercontinental airliner and in QF service was operating sectors as long as SYD-PEK.
