Are Propane Generators Better Than Gas (Propane Vs Gas Generator)

When it comes to generating power, everybody has different requirements. The decision between a gas or propane generator is mostly based on your intended purpose.

We present an approach in this article to assist you in making the best generator decision possible.

A dual-fuel generator is recommended if you reside in a region where hurricanes are predicted or plausible.

Are Propane Generators Better Than Gas (Propane Vs Gas Generator)

When fuel is limited, you'll probably want the choice of using both gas and propane to generate electricity. 

Propane has an unlimited shelf life (this means that it does not perish or go bad), whereas gasoline has a shelf life of around a year (with fuel stabilizers).

When catastrophe hits, it's wise to have as many options available to you as possible.

Gas Vs Propane

In order to work correctly, every generator requires fuel. Historically, this was always either gasoline or diesel.

Yet, propane, also known as Liquefied Petroleum Gas (LPG), has grown in popularity as a generating fuel in the past few years. 

Propane possesses certain combustion properties that are quite similar to ordinary gasoline, and it could even use the same carburetor.

This allows you to utilise any fuel in the very same generator, as long as the generator is made to handle both varieties.

Dual-fuel generators are those that can run on either natural gas or propane.

There is also a lot of disagreement about whether propane or gas is preferable.

These topics will be discussed in depth in this post. In some ways, the choice between a propane and a gas generator seems to be more of a subjective one. 

There isn't anything that differentiates the generator's true abilities.

One major distinction is that a propane-powered generator may not have the same watt capacity as a gas-powered generator with the very same motor.

When contrasted to an equal gas generator, a propane generator will normally provide 10–15 percent less power.

Gas Generators 


  • An internal combustion engine drives a propeller to spin an armature inside a gas generator. The armature generates magnetic waves, which aids in the operation of the gas generator. The cost of gas is among the most prominent reasons some people pick it. Purchasing and installation costs for gasoline generators are often substantially lower.
  • In addition, gas generators are capable of producing more heat than that of propane generators, roughly 30% more for the very same quantity of fuel. Gas generators are also far more mobile thanks to their small dimensions. Unlike propane generators, which already have tanks on the outside, gas generators have tanks on the inside, giving them the ability to be moved easily.


  • If stored in a generator tank, gas deteriorates with time. To preserve the fuel's freshness, it must be replenished on a frequent basis. If you just want to keep gas fresh, you must change it at least every six months if it's stored in a generator or perhaps another tank. 
  • Gas is also less environmentally friendly than propane. It has greater negative environmental consequences because it is a dirty fuel. Before deciding on a fuel, this is a crucial factor to think about.  In addition, gas generators are less efficient than propane generators. Unlike propane, which can be hooked up to a tank and be prepared to use at all times, you'll have to take a trip to a gas station to buy gas for your fuel generator.

Propane Generators


  • Propane is just another by-product of the natural gas and petroleum refineries. Propane generators are available in both stationary and portable models, but can be used to power a variety of devices and equipment.
  • Propane, if using it as a generator fuel, can provide a range of critical advantages not seen in other varieties of generator fuel. Propane is a hygienic gas with a long shelf life. A propane tank with a volume of less than 100 pounds has a typical expiry date of 12 years after the time of production. Once the tank reaches its expiry date, it must be removed or evaluated to see whether re-qualification is available, which might extend the tank's life by another five years.
  • Another significant advantage of employing a propane generator would be that the flow of propane will not be affected in the event of a catastrophe or any other crisis. Even though you might assume the gas pumps to stop working within a brief span of time, the propane supply should last considerably longer. Propane is kept in canisters, making it not only easily accessible but also to preserve for lengthy periods of time.
  • Propane is a reduced noise fuel which is both pure and eco friendly. The fuel combusts cleanly, which means it creates less carbon monoxide (CO), which can cause suffocation in excessive volumes. Crops and other living things can be harmed by carbon monoxide. Propane is significantly less damaging to people and nature because of its low CO content.


  • Although propane generators are among the most environmentally friendly and long-lasting alternatives, they do have certain drawbacks. Propane generators are much more costly than gasoline generators, which are more inexpensive. Furthermore, propane generators are reported to produce up to 30% less warmth than gasoline-powered devices. Propane generators are also bigger than gasoline generators, which makes them more challenging to manoeuvre.

Bottom Line

Decide which elements of the fuel are most important to you before selecting a generator.

If you're on a limited budget and don't mind replacing your fuel every now and again, an inexpensive gasoline generator might be the ideal option for you. 

A propane generator could be the best option if you want a fuel that does not degrade with age and are ready to pay a higher price for it.
