That's not too high a fuel useage number IME. Some people simply have no idea how much more fuel it takes to mulch, especially if there are leaves and more so if they are damp or wet. There's a lot more material staying under the deck, and on top of that, the blades are trying to move a lot of air when there's not much place for it to easily escape. It takes more fuel to mulch than it does to cut long grass, and that's based on first hand experience doing both with the same deck on the same machine.
