Knowing how long a 6500 watt generator will run can be helpful for purposes like planning refueling sessions. Discover a few numbers.
The first thing you want to know is that 6500 watt generators can vary a lot in terms of how long they can run from brand model to brand model.
At the same time, you can still say 6500 watt generators will often run around 14 hours at 25% load and around 11 hours at 50% load.
You can check out the rest of the article to get more precise numbers per brand model, see what 6500 watt generators stand out, and see the run times on 5 gallons of gas.
How long will a 6500 watt generator run on a tank of gas?
While knowing whether a 6500 watt generator can run what you need is important, having an idea of how long the machine can do this is relevant too.
That being said, you want to know that there is not really a general number for how long a 6500 watt generator can run on a tank of gas.
Instead, generator brands can make their machines with different specifications in this area.
To help you get an idea of what you can expect, I listed the 6500 watt generators in the table below together with their run times.
One thing to keep in mind when looking at this table is that you can’t really compare run times at different loads.
A run time at 50% load is not necessarily half as long as a run time at 25% load.
| 6500 Watt Generator Name | Run Time @25% Load | Run Time @50% Load | Run Time @Rated Load | Peak/Starting Watts | Continuous Watts |
|---|---|---|---|---|---|
| Predator 6500 | Not Mentioned | 14.5 Hours | Not Mentioned | 6500 Watts | 5500 Watts |
| Honda EM6500S | Not Mentioned | 9.8 Hours | 6.4 Hours | 6500 Watts | 5500 Watts |
| Briggs & Stratton Q6500 | 14 Hours | Not Mentioned | Not Mentioned | 6500 Watts | 5000 Watts |
| Westinghouse WGen5300v | 14.5 Hours | Not Mentioned | Not Mentioned | 6600 Watts | 5300 Watts |
| Westinghouse WGen5300DFv | Not Mentioned | 11 Hours (Gasoline) | Not Mentioned | 6500 Watts | 5300 Watts |
| Champion 5250/6500 | 13.5 Hours | Not Mentioned | Not Mentioned | 6500 Watts | 5250 Watts |
| Pulsar G65BN | Not Mentioned | 11.5 Hours (Gasoline) | Not Mentioned | 6500 Watts | 5500 Watts |
How long will a 6500 watt generator run on 5 gallons of gas?
It is also possible that you have a certain amount of gas in mind and want to know how long a 6500 watt generator can run with this.
In the table below, you can find how long 6500 watt generators would last while running at the different loads.
You can say 6500 watt generators can run around 15 hours at 25% load and around 11 hours at 50% load on 5 gallons of gas although individual models vary.
Again, the fuel usage per hour is not the perfect detail to compare generators with due to the different loads.
| 6500 Watt Generator Name | Run Time @25% Load | Run Time @50% Load | Run Time @Rated Load | Fuel Usage Per Hour | Fuel Tank Size |
|---|---|---|---|---|---|
| Predator 6500 | Not Mentioned | 9.30 Hours | Not Mentioned | 0.54 Gallons @50% Load | 7.79 Gallons |
| Honda EM6500S | Not Mentioned | 7.90 Hours | 5.2 Hours | 0.63 Gallons @50% Load | 6.2 Gallons |
| Briggs & Stratton Q6500 | 14.00 Hours | Not Mentioned | Not Mentioned | 0.36 Gallons @25% Load | 5 Gallons |
| Westinghouse WGen5300v | 15.40 Hours | Not Mentioned | Not Mentioned | 0.32 Gallons @25% Load | 4.7 Gallons |
| Westinghouse WGen5300DFv | Not Mentioned | 11.7 Hours (Gasoline) | Not Mentioned | 0.43 Gallons @50% Load | 4.7 Gallons (Gasoline) |
| Champion 5250/6500 | 15.70 Hours | Not Mentioned | Not Mentioned | 0.32 Gallons @25% Load | 4.3 Gallons |
| Pulsar G65BN | Not Mentioned | 11.1 Hours (Gasoline) | Not Mentioned | 0.45 Gallons @50% Load | 5.2 Gallons (Gasoline) |
