Fuel use
| Fuel | Half load | Full load |
|---|---|---|
| Propane | 4.5 gal/hr | 8.7 gal/hr |
| Natural gas | 512 ft³/hr | 875 ft³/hr |
On propane, a 500-gallon tank filled to 80% holds about 400 gallons. That runs the Kohler 48RCLC for about 89 hours (3.7 days) nonstop at half load, or about 46 hours (1.9 days) at full load. See how much propane a generator uses for other tank sizes.
On natural gas, the gas line and meter have to deliver the full-load figure, 875 ft³/hr, even if the generator rarely runs that hard. Installers size the pipe to it.
