The manufacturers typically have technical info on their web sites that show consumption vs generator size at 25, 50, 75, 100% of full capacity. For a 14-20 KW unit, consumption averaged over time could be up to 2-3 gallons/hr. There will be a small amount used for periodic auto-test. For my 14KW Kohler, that is 20 minutes once per week, at low % of full power, whatever that comes out to.
Our 500 gallon tank started out at 80-85% full in March of 2016. A few short-duration outages and weekly testing had brought it down to around 80% on the little gauge by this winter. After the March 14 storm outage of about 30 hours, it was down to around 70%. Those are very crude estimates, as I wasn't really concerned about levels. I think that if we expected a really lengthy outage, then we'd start doing things like shutting it down overnight and watching our electrical usage more, to make the tank last longer.
