How long will a generator run on propane vs gasoline?

A generator running on propane will have three times more runtime compared to a generator running on gasoline. Depending on how much gasoline and propane you are using, the amount of time the generator runs might vary.

If we fill one generator with gasoline and another with propane respectively with the quantity of 1.1 gals of fuel in each of them, you will find that the generator runs on gasoline for 11 hours and on propane for 34 hours.

Does a generator run better on gas or propane?

A generator runs better on gas in comparison to propane. Though generators running on propane are environment friendly as they tend to release less carbon emission, they are less efficient in terms of producing electricity.

Generators running on propane tend to produce 25 – 30 % less electricity compared to generators running on gasoline. It is because gasoline has a better BTU per gallon of fuel than propane.

Is it cheaper to run a generator on propane or natural gas?

It is cheaper to run a generator on natural gas compared to propane. Though prices fluctuate based on global demand, it can be said that generally, propane is far more expensive than natural gas.

If you look into the numbers, you will find that one-gallon propane will cost you 2.41 $. Whereas for a similar quantity of natural gas, you will have to spend 0.86 $.

So, you can easily understand that it is cheaper to run a generator on natural gas compared to propane.

Can portable generators run on natural gas?

Yes, a portable generator can run on natural gas if it is a tri-fuel or natural gas portable generator. Portable generators are built to run either on propane or natural gas.

If your portable generator can run on natural gas natively, you can use it without any issue with natural gas.

Various brands are introducing tri-fuel portable generators which can run on gasoline, propane, and natural gas. Those can also run on natural gas without any problem.

Can a propane generator be converted to run on natural gas?

Yes, a propane generator can be converted to run on natural gas. A propane generator can not run on natural gas without any modifications.

There are conversion kits available in the market to make your propane generator run on natural gas.

Conversion kits are necessary because the propane generators run on a different mixture of fuel which might not be compatible without the conversion kit. Therefore, if you buy the kit and convert your propane generator, you will be able to use it with natural gas.

Final thoughts

A dual fuel generator can run on natural gas. To run it on natural gas, you will have to use a conversion kit, which you will have to attach to your dual fuel generator with proper modifications. Without these modifications, it is not possible to use your dual fuel generator on natural gas.
