Can a Generator Run on Propane and Gas?

Apr 22,2023 | YESGENERATOR

Understanding the Versatility of Dual Fuel Generators and Their Fuel Sources

dual-fuel generators

When it comes to powering your generator, the choice of fuel plays a crucial role in its performance and functionality. One common question is whether a generator can simultaneously run on propane and gas.

This article will delve into the world of dual-fuel generators, examining their capabilities, fuel options, and the benefits they offer users. Let us explore how these versatile power stations can provide reliable and flexible energy solutions.


Dual Fuel Generators: The Best of Both Worlds

Propane and Gasoline Tanks

Dual fuel generators have gained significant popularity recently due to their ability to run on propane and gasoline. This unique feature allows users to switch between fuel sources, maximizing convenience and versatility. Whether you prefer the long shelf life and cleaner burning qualities of propane or the availability and convenience of gasoline, a dual-fuel generator provides you with the best of both worlds.


The Advantages of Dual Fuel Generators

Extended Runtime: With a dual-fuel generator, you can expect extended runtime compared to a single-fuel generator. By utilizing propane and gasoline, you can easily switch to an alternative fuel source when one runs out, ensuring continuous power supply during extended outages or emergencies.

Fuel Availability: One of the significant advantages of dual fuel generators is their flexibility in fuel availability. While gasoline can be easily obtained from gas stations, propane can be conveniently sourced from tanks or cylinders. This accessibility allows users to power their generators even in remote locations or areas where gasoline is not readily available.

Smooth Transition with Automatic Transfer Switch (ATS): For those seeking a seamless transition between utility and backup power, a dual-fuel generator combined with an automatic transfer switch (ATS) is ideal. An ATS detects power outages and automatically starts the generator, ensuring an uninterrupted power supply. This setup is handy for home standby generators, where reliable and automatic power restoration is essential.

Exploring propane as a Fuel Source


Clean Burning: Propane is known for its clean-burning properties, making it an environmentally friendly choice for powering your generator. It produces lower emissions of harmful pollutants, such as carbon monoxide, than gasoline. This cleaner burn is not only beneficial for the environment but also extends the lifespan of your generator's engine.

Shelf Life: Propane offers an advantage in terms of shelf life. Unlike gasoline, which can degrade over time, propane has an indefinite shelf life when stored properly. This makes it an excellent option for long-term storage and emergency preparedness.

Gallons of Propane: The propane required to power a generator depends on its fuel consumption rate and power output. As a general guideline, a 20-pound propane cylinder can typically provide around 10-12 hours of runtime for a mid-sized portable generator operating at 50% load. For longer durations, larger propane tanks or refillable cylinders are recommended.


Gasoline: A Convenient Fuel Option


Wide Availability: Gasoline is readily available at gas stations nationwide, making it a convenient and easily accessible fuel source for your generator. This accessibility ensures you can refuel your generator without hassle, especially during emergencies or extended power outages.

Fuel Generators and Inverter Technology: Gasoline-powered generators are commonly found in portable power equipment due to their versatility and affordability. Inverter generators, in particular, provide stable and clean power output suitable for sensitive electronics, making them popular for recreational activities, camping trips, and outdoor events.


Making an Informed Decision

When choosing between propane and gasoline as fuel sources for your Generator, consider the following factors:
Power Output: Determine the power requirements of your appliances and equipment to ensure your generator can meet the necessary demands.

Runtime: Assess the expected duration of power outages or the desired runtime for specific applications to select the appropriate fuel type and storage capacity.

Environment: If environmental impact and emissions reduction are essential to you, propane is a cleaner-burning alternative that minimizes carbon monoxide emissions.

Long-Term Storage: If you anticipate storing fuel for an extended period, propane's indefinite shelf life may be advantageous.


Dual fuel generators allow users to choose between propane and gasoline, offering extended runtime and fuel availability. Whether you opt for propane's cleaner burn and indefinite shelf life or gasoline's widespread availability, a dual fuel generator ensures you have a reliable backup power solution for your home or on-the-go power needs.

Consider your power requirements, runtime expectations, and environmental considerations to decide which fuel type best suits your needs.
