5 Best Tri Fuel Generators 2024 (+Pricing, Pros and Cons)

tri fuel generator

Tri fuel generators offer a versatile and reliable power solution by allowing users to switch between three different fuel sources: gasoline, propane, and natural gas. This flexibility ensures uninterrupted power supply during emergencies, outdoor activities, or off-grid living. In this article, we will explore the five best tri fuel generators available in 2024, along with their pricing, pros, and cons, to help you make an informed decision.

What is a tri fuel generator?

A tri fuel generator is a type of generator that is designed to operate on three different fuel sources: gasoline, propane, and natural gas. This versatility allows users to choose the fuel option that best suits their needs, circumstances, and fuel availability.

Tri fuel generators typically come equipped with a fuel selector switch or valve that allows users to easily switch between the different fuel sources. This flexibility is especially beneficial during emergencies or situations where a particular fuel type may be scarce or unavailable.

Gasoline is the most commonly used fuel option for tri fuel generators. It is readily available at gas stations and provides a convenient power source. Propane, also known as liquefied petroleum gas (LPG), is a cleaner-burning fuel that offers longer shelf life and reduced emissions compared to gasoline. Natural gas, on the other hand, is often sourced from utility pipelines and provides a continuous supply without the need for refueling.

The ability to use multiple fuel sources makes tri fuel generators highly versatile and adaptable. They are commonly used for various applications, including backup power during power outages, camping trips, outdoor events, construction sites, and remote locations where access to a specific fuel source may be limited.

Pros of Tri Fuel Generators

Tri fuel generators offer several advantages that make them a popular choice for individuals and businesses alike. Here are some of the key pros of tri fuel generators:

  • Fuel Versatility

The ability to operate on three different fuel sources (gasoline, propane, and natural gas) is a significant advantage of tri fuel generators. This versatility allows users to adapt to varying fuel availability and choose the most convenient and cost-effective option for their specific needs. It ensures a continuous power supply even when a particular fuel type is scarce or unavailable.

  • Extended Run-Time

Tri fuel generators typically have longer run-times compared to single-fuel generators. By using propane or natural gas, which often have larger fuel storage capacities, these generators can provide power for extended periods without the need for frequent refueling. This is especially beneficial during prolonged power outages or situations where refueling may be challenging.

  • Easy Fuel Switching

Tri fuel generators are designed with user-friendly fuel selector switches or valves that allow for seamless switching between fuel sources. Users can quickly transition from one fuel type to another without any complicated procedures or downtime. This convenience adds to the overall usability and flexibility of the generator.

  • Environmental Considerations

Propane and natural gas are cleaner-burning fuel options compared to gasoline. They produce fewer emissions, reducing the environmental impact of power generation. By utilizing these cleaner fuels, tri fuel generators contribute to a greener and more sustainable power solution, particularly in environmentally sensitive areas or situations where emissions need to be minimized.

  • Adaptability to Different Applications

Tri fuel generators are versatile and can be used for various applications. They are suitable for both residential and commercial use, providing reliable power during emergencies, outdoor events, construction sites, camping trips, and off-grid living. The ability to choose from different fuel sources ensures compatibility with a wide range of power needs and scenarios.

  • Backup Power Reliability

Tri fuel generators are often chosen as backup power solutions due to their reliability. They offer a dependable power source during power outages, ensuring that essential appliances, medical equipment, and critical systems continue to function. The option to switch between fuel sources provides added peace of mind and ensures uninterrupted power supply when it is needed the most.

Cons of Tri Fuel Generators

While tri fuel generators offer numerous advantages, it is important to consider their potential drawbacks as well. Here are some cons associated with tri fuel generators:

  • Higher Initial Cost

Tri fuel generators often come with a higher initial cost compared to single-fuel generators. The inclusion of additional components and the flexibility to operate on multiple fuel sources can increase the price of these generators. However, it is essential to weigh the upfront cost against the long-term benefits and versatility provided by tri fuel generators.

  • Larger and Heavier Design

Tri fuel generators tend to be larger and heavier than their single-fuel counterparts. The inclusion of multiple fuel systems and larger fuel storage capacities can result in a bulkier and less portable generator. This can make transportation and storage more challenging, particularly if you require a generator for on-the-go or mobile applications.

  • Noise Levels

Tri fuel generators, especially those running on gasoline, can produce noise during operation. While efforts have been made to reduce noise levels in modern generator models, some users may find the noise output to be relatively higher compared to other power sources. This can be a consideration, particularly in noise-sensitive environments or when using the generator in close proximity to living spaces.

  • Maintenance Requirements

Tri fuel generators may require additional maintenance compared to single-fuel generators. The presence of multiple fuel systems means that each component needs to be properly maintained and serviced. This includes regular inspection, cleaning, and potential adjustments to ensure optimal performance and fuel switching functionality. It is important to follow the manufacturer’s maintenance guidelines to keep the generator in good working condition.

  • Availability of Fuel Sources

While tri fuel generators provide the advantage of fuel versatility, the availability of different fuel sources can vary depending on your location. While gasoline is generally widely accessible, propane and natural gas availability may be more limited in certain areas. It is important to consider the availability and accessibility of the desired fuel sources in your region before investing in a tri fuel generator.

Despite these potential drawbacks, many users find that the benefits and flexibility offered by tri fuel generators outweigh the cons. It is crucial to carefully evaluate your specific needs, budget, and circumstances to determine if a tri fuel generator is the right choice for you.

In conclusion

Tri fuel generators provide a convenient and flexible power source, allowing users to switch between gasoline, propane, and natural gas. The five models discussed in this article offer reliable performance with their own set of pros and cons. Consider your power requirements, budget, and specific needs before making a purchase decision. Whether it’s for emergency backup power or outdoor activities, a tri fuel generator can be a valuable investment for uninterrupted power supply.


  • What is the difference between Tri-Fuel and dual fuel generators?

The main difference between tri-fuel and dual fuel generators is the number of fuel types they can run on:

1.Dual fuel generators can operate on two fuel types, usually gasoline and propane or natural gas. This gives some flexibility in fuel options.

2.Tri-fuel generators can run on three fuel types – gasoline, propane, and natural gas. This gives even more flexibility and versatility in fuel choice.

  • Is a Tri Fuel Generator Right for Me?

Tri fuel generators can power entire homes but dual fuel models may be adequate for smaller needs. The extra fuel flexibility of tri fuel units comes at a higher cost. Consider your access to natural gas and propane when deciding if the cost is justified. Also factor in maintenance, transport needs, and your specific power requirements. For most homes, a dual fuel generator provides sufficient backup capability. But for large homes, available gaseous fuels, or off-grid use, a tri fuel generator may be the optimal choice.
