Years ago, I studied the various catalogs, and did some

As such, plan to feed your generator a galon an hour.

In real life you don't run things at full load. My 5500watts Briggs
and Stratton with a 7 gallon lasts 13 hours at 1/2 load. [and in
practice that seems to be about what it gets.]

The Honda should do better as it regulates engine speed.
