How long will 100 gallons of propane last for a generator?

36 hours
A 7kW generator will run for 66 hours, a 12kW generator will run for 36 hours on a 100 gallon tank at full load. Most of the time, the generator is operating between 25-75% capacity and the fuel supply will last much longer.

What lasts longer gas or propane generator?

Natural gas provides about 1,040 BTUs per cubic foot, while propane provides 2,490 BTUs per cubic foot. This means that in the same time period, you’ll burn more than twice as much natural gas as you would propane. But if running out of fuel is a concern, propane is a better choice because it will last you longer.
