Discover how long a 6000 watt generator can run to plan your refueling sessions or see whether they are good for overnight AC duty.

Before going into some rough numbers, you need to know that individual brand models can and often vary in terms of run times.

At the same time, you can say that 6000 watt generators will often run around 13 hours at 25% load and 8 to 9 hours at 50% load on a full tank of gasoline.

There are also a few dual fuel 6000 watt generators but you can not really put a general number on how long these run on propane.

You can also check out the different 6000 to 6300 peak watt generators and their run times in the table below.

How long 6000 watt generators run on a tank of gas

It is interesting to see what a 6000 watt generator can run but you likely also want to know how long you can do this on a tank of gas.

You can say that 6000 watt generators typically run around 13 hours at 25% load and around 8 to 9 hours at 50% load.

That being said, there are definitely also generator brand models that have run times higher and lower than these numbers.

If you want to be 100 percent sure, you would check how long your specific 6000 watt generator can run on a tank of gas in the table below.

One quick note is that run times at 25% load are not necessarily double that of 50% load. There is not really a perfect conversion in this area.

How long 6000 watt generators run on propane

A few of the 6000 watt generators in the table below are dual fuel models which means they can also run on propane (LPG).

When running on propane, the generators have different watt capacities and run times.

You can find how long the dual fuel watt generators can run on a 20 lb tank of propane (when this info was available) in the table below.

FAQ

How long does a 6000 watt generator last?

6000 watt generators will typically last around 13 hours at 25% load and around 8 to 9 hours at 50% load on a full tank of gas.

In terms of durability and not run time, it is hard to put a number on how long a 6000 watt generator lasts.

Even two generators of the same model design can vary in terms of durability.
