The theory is (on paper) that filling up less often means you carry less weight. More than likely you can calculate this difference on paper and its so small wont actually see it.
Then you get into the whole "in tank fuel pump immersion debate" where immersing the fuel pump in fuel (not letting the tank drop much below 3/4) cools the fuel pumps motor allowing it to last a lot longer.
