Figures are fuel consumption values at 100% (full) load. It is unlikely that the generator would run at full load for an extended period of time. Therefore, your consumption would decrease accordingly.

The generator will still run at 3600 rpm, independently from the load. At half load, the fuel savings would be only 20%.
