It also does not have any expiration date. So if you’re using a tank, you can fill it and have extra propane available whenever the need arises.

2. No contamination

Propane that has been stored for some time won’t be contaminated. If you’re worried about carbon deposits. Propane is less likely to have residue.

3. Cleaner energy

Propane has lesser by-products and emits less carbon monoxide. So it’s a great option for those who are looking for a cleaner and greener source of fuel.

6. Lower operating cost

Propane Vs Gas Generator

For decades, gas has been a more popular choice for fuel. It has been a familiar energy source for most people. But it can have a lot of side effects. Propane, on the other hand, seems to be a better choice. 

Let’s compare propane and gas side by side to see their differences.

  • Gas is highly combustible while propane produces less carbon monoxide

Propane is the greener choice because it provides nearly half the carbon monoxide gas and diesel produce. And among the types of fuel, gas can be highly polluting. Yes, it’s a popular choice of many because of familiarity. But it’s highly combustible and can release a ton of harmful gases into the air.

  • Gasoline is more expensive

Gas can be quite expensive. It can’t be stored longer as it can be dangerous. That’s why it can cost more. Propane, on the other hand, can be stored for a longer time. It’s safe and does not expire. Therefore, that accounts for why propane costs less than gas. 

  • Gasoline generators are more mobile than propane

This is one of the advantages of a gas generator, it‘s more mobile and portable so it’s easy to bring it wherever they need maybe. That’s why it’s a popular choice for camping or going off the grid. Propane generators, on the other hand, can have a substantial weight. 

  • Gas is easily accessible

While propane is widely available nowadays, gas is more readily available in all gas stations. And propane might not be fully available yet in remote areas.

  • Propane is a better alternative for people with allergies

The smell of gas can be harmful, yes. But it can be worse for those with allergies. And propane is a better alternative since it’s a cleaner energy source. it’s also less likely to cause allergies. 

  • Gas has higher maintenance

Propane virtually requires little to no maintenance and upkeep. It does not leave any residue, unlike gas. Gas also increases your operating cost since there’s a need for more regular upkeep.

  • Gas degrades easily

Gas can only last for a maximum of 12 months. So you can’t store it for a long time. Also, it’s not safe to store gas in large amounts. Propane, on the other hand, can be stored longer without any danger. And it does not need stabilizers to keep its quality.

How Does a Propane Generator Work?

The generator will burn propane to create heat and energy. 

A mixture of water and ammonia is already present in the generator. The heat produced will make ammonia reach its bunting point. Hence, it is converted into ammonia gas. And this gas flows through the generator.

Typically, propane generators work in the same way as other types of generators. The only difference is that it has specialized carburetors. These are needed to burn propane.


Can propane make the engine hotter and more dangerous?

It is a usual misconception when choosing between diesel or propane-powered generators. In actuality, propane has a lower Btu’s than gasoline when undergoing combustion. However, it’s essential to put the correct fuel based on the generator’s specifications.

How can I make my engine last longer?

Each generator would have a specific maximum running time that you cant change. However, some generators have built-in features that protect the engine from power surges and ensures that it can work longer. It would be suggested to look for features such as oil shutdown mechanism, voltage regulator, and automatic idle function to have a long-lasting generator. 

How do I know if the generator is RV ready?

The generator intended to power the RV AC unit, and other appliances should have at least a 2000- 4000-watt capacity. You also have to check if the generator has a built-in outlet compatible with RV plugs or power cord. 

How loud are propane generators?

Most propane generators are relatively quiet, they produce as little as 60 decibels.

What Is A Dual Fuel Generator?

This type of generator uses two types of fuel. And this can be convenient if one energy source is not available, you have a backup.


Buying the best propane generator is a good investment in cases of a power outage due to calamities and other unforeseen situations. It’s also a machine that can aid you if you’re doing heavy-duty labor outside. Make sure that you buy the best generator so you will be worry-free whenever there is no source of electricity.
