Key Takeaways

  • Since propane does not deteriorate, propane-powered generators last longer than gas-powered ones. 
  • Propane generators are more difficult to fix on your own due to their more complicated mechanics. 
  • When compared to gasoline generators, propane generators emit roughly half as much carbon monoxide.
  • Propane generators will cost more to run than gas generators in 2023.

Are you tired of being left in the dark during a power outage? Are you ready to take the plunge and invest in a generator, but you’re not sure whether to go with propane or gas?

In one corner, we have the clean-burning, fuel-efficient propane generator. The other corner has the tried and true, always-available gas generator.

Who will come out on top?

Fear not, my friends, because we’re here to help you make the tough decision between these two power-providing giants!

Propane Vs Gas Generator head to head comparison

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

Operating a generator on gas is more expensive than propane.

Propane for powering a generator in 2023 costs about $2.85 per gallon, while gasoline costs about $3.31 per gallon.

 

Gas vs Propane Generator: Head-to-Head Comparison

Let’s dive in and see which type of generator will reign supreme in the battle of propane vs gas!

Cost

In most cases, the price of propane is higher than the price of natural gas. Propane is typically sold in lower quantities, which makes it more expensive to purchase in big numbers for generators. Additionally, you also need a tank & proper storage system for propane, which might increase the overall cost. 

Natural gas, on the other hand, is less expensive, more readily available, and does not call for the use of tanks for its storage.

 

Portability

Generally, propane generators are more portable than gas generators, Propane is a lighter fuel than gas, so a propane generator will typically be lighter and easier to carry than a gas generator of the same size. Propane is also easier to store and transport than gas, making it a good choice for portable generators. 

However, it is worth noting that there are many other factors that can affect the portability of a generator, such as the overall size and weight of the unit, the type of handle or wheels it has (if any), and the availability of an easy-to-use carrying case or bag. So, it’s always a good idea to carefully consider all of these factors when choosing a portable generator.

 

Maintenance Requirements

The requirements for maintaining & storing a generator that runs on propane or gas are comparable. 

Both kinds of generators need to have their oil and air filters checked and changed on a regular basis, and they also need the regular cleaning of spark plugs & carburetors. It is essential to adhere to the instructions provided by the manufacturer regarding the intervals at which maintenance should be performed. Failing to perform regular maintenance might lower the performance of the generator and limit its lifespan. 

Due to the corrosive nature of propane gas, additional general maintenance activities, such as cleaning the fuel line and fuel filter more frequently, may be required for propane generators. To stop gas leaks, it’s also important to ensure the propane tank is well-secured, and all connections are tight.

 

Voltage Regulations

No matter what kind of fuel a generator uses, it has no effect on voltage regulations. 

Voltage regulation means that a generator can keep its output voltage the same even if the load or engine speed changes. 

Propane and gas generators can have good or bad voltage regulation depending on how well they were designed and built. When choosing a generator, it is essential to give careful consideration to the voltage regulation capabilities of the unit, as insufficient voltage regulation can lead to the malfunctioning or destruction of electronic devices

 

Transfer Switch Option

One of the benefits of propane generators is that they may be fitted with an automatic transfer switch. This transfer switch can detect when there is a disruption in the power supply and trigger the generator to begin operating on its own. In the event of an unexpected power outage, you won’t have to waste time manually starting the generator thanks to this feature. 

On the other hand, gas generators may also be fitted with a transfer switch; nevertheless, in the event that there is a power disruption, the generators may need to be started manually. 

However, gas generators have the benefit of being able to run for extended periods of time without the need to be refilled. This could be an advantage for you if you require a long-term solution to your power needs.

 

Resale Value

When it comes to resale value, both propane and gas generators can hold their value well if they are well-maintained and in good condition. However, here are a few factors that affect the resale value.

The demand for the generator’s fuel is one thing to think about. In general, generators that run on a more extensively used fuel, like gas, may fetch a greater price on the secondary market.

Generator quality is another aspect. Generators from trusted, high-quality brands may have a higher resale value.
