How much gas does the WGen9500TFc use?
- At 25% load: 6.6 gal ÷ 15 h ≈ 0.44 gallons per hour
- At 50% load: 6.6 gal ÷ 10 h ≈ 0.66 gallons per hour
These are our calculations from Westinghouse's published tank size and runtimes, not Westinghouse figures.
Manufacturer figures vs. our estimates
Only the runtimes listed above are Westinghouse's own published figures. When your load and fuel amount exactly match one of them, the calculator labels the result Manufacturer Published Runtime. Loads between published figures are labeled Estimated from Manufacturer Data, and loads outside the published range are labeled Extrapolated with a wider range. Those are GeneratorRuntime estimates, not Westinghouse specifications.
Operate it safely
Like every portable generator, the Westinghouse WGen9500TFc must be operated according to the manufacturer's safety instructions: outdoors only, well away from doors, windows, and vents, with battery CO alarms inside your home. A CO shutoff feature is not a substitute for safe placement. Never refuel while the engine is running or hot.
Westinghouse WGen9500TFc FAQ
›How long will a WGen9500TFc run on gasoline?
Westinghouse lists 15 hours at 25% load and 10 hours at 50% load on the 6.6-gallon tank.
›How long will a WGen9500TFc run on propane?
Westinghouse lists 8.75 hours at 50% load but does not state the propane quantity, so the calculator does not scale it to other tank sizes.
›How long will it run on natural gas?
Natural gas comes from a utility line, so there is no tank to run out. Westinghouse does not publish a natural-gas consumption figure for this model.
›Is this the same as the WGen9500 or WGen9500DF?
No. The WGen9500TFc (part number 9537) is the tri-fuel EFI model with a CO sensor: gasoline 9,500 watts running / 12,500 watts peak, propane 8,500 watts / 11,200 watts, natural gas 7,500 watts / 9,500 watts. The WGen9500 and WGen9500DF are different generators.
