Having a generator is a great way to ensure that you have power in the event of an emergency. There are many ways to run a generator, but one of the most popular is using propane. So, how long will a generator run on propane?
The answer to this question depends on a few factors, including the size of the generator and the amount of propane you have. In this guide, we’ll answer that question and give you some tips on how to make sure your generator is always ready to go when you need it.
How Long Will A Generator Run On Propane?
The answer to this question depends on a number of factors, including the size of the generator and the amount of propane you have. Generally speaking, a generator will last for up to about 8 hours on a full tank of propane. However, this is only true if the generator is running at half load. If you are running the generator at full load, it will only run for about 4 hours on a full tank.
To get the most out of your propane generator, it’s important to understand how long it will run on a full tank. This way, you can plan ahead and make sure you have enough propane on hand to power your generator for the duration of an outage.
To better understand, the list below includes some of the most popular generator sizes and how long they will run on a full tank of propane.
- 6,000 watt generator = 8 hours
- 10,000 watt generator = 7.5 hours
- 12,000 watt generator = 6.8 hours
- 15,000 watt generator = 5.3 hours
As you can see, the larger the generator, the less time it will run on a full tank of propane. This is because larger generators require more fuel to run. If you have a large generator, you may want to consider investing in a second tank of propane so that you can extend the runtime of your generator.

The following are some of the types of generators that run on propane: portable and standby.
Portable Generators
This type of generators are the most popular type of generator on the market. They are small and easy to transport, making them ideal for use in an emergency situation. This is beneficial if power outages are common in your area.
Portable generators typically range in price from $500 to $1,500.
Standby Generators
Standby generators are larger and more expensive than portable generators. They are designed to be installed permanently at your home or business. This is beneficial if you want to be prepared for a long-term power outage.
Standby generators typically range in price from $2,000 to $10,000.

There are a few things you can do to make sure your propane generator is always ready to go when you need it.
Invest in a quality generator
This may seem like an obvious tip, but it’s worth repeating. A quality generator will not only last longer, but it will also be more efficient and use less fuel. When shopping for a generator, look for one that is certified by the Environmental Protection Agency (EPA). This certification means that the generator meets strict emissions standards.
Another thing to look for when shopping for a generator is a fuel gauge. This feature will help you keep track of how much fuel is in the tank so that you can plan accordingly.
Store propane in a cool, dry place
When storing propane, it’s important to choose a cool, dry place. Exposure to heat can cause the propane to expand and leak from the tank. If you live in an area with extreme temperatures, consider storing your propane tanks in a temperature-controlled space.
Check for leaks before using
Before using your generator, it’s important to check for leaks. To do this, mix a solution of soap and water and apply it to the connections on the propane tank. If you see any bubbles, this indicates a leak.
If you find a leak, do not attempt to repair it yourself. Call a qualified technician to fix the problem.
Keep your generator clean
A clean generator is a happy generator. Be sure to clean your generator regularly to prevent build-up and corrosion. This will also help it run more efficiently.
Final Thoughts
Generators are a great way to keep your home or business powered in the event of an outage. However, it’s important to understand how long they will run on a full tank of propane. This way, you can plan ahead and make sure you have enough fuel on hand to power your generator for the duration of an outage.
Now that you know how long a generator will be running on propane, you can be sure to have enough fuel on hand when the power goes out. By following the tips in this guide, you can also extend the lifespan of your generator and keep it running smoothly for years to come. Now you’ll be prepared for anything!
