frequently asked questions
frequently asked questions
How long does a dual fuel generator run on propane?
A standard 20-pound propane tank can power most generators for about 5 hours, depending on load. Some models, like the BISON smart generator with a 4L tank and 1600–1800W output, can run up to 12.5 hours on LPG due to higher efficiency.
Can I run a dual-fuel generator on both fuels at the same time?
No, dual-fuel generators are designed to operate on one fuel at a time. However, you can switch between gasoline and propane as needed—even during operation.
How long can a dual-fuel generator run on a single tank of fuel?
Runtime depends on the generator’s size, load, fuel type, and tank capacity. Gasoline models typically run 6–12 hours on a full tank, while propane can offer longer runtime. For example, a 5-gallon gasoline tank may power a generator for about 8 hours under moderate load. Heavier loads reduce runtime due to higher fuel consumption.
How do I maintain my dual-fuel generator?
Regular maintenance includes checking and changing the oil, cleaning the air filter, inspecting the spark plugs, and keeping the fuel system clean. Always refer to your generator’s user manual for detailed service intervals and procedures.

In today’s world, having flexible and reliable power is more important than ever. Whether dealing with unexpected outages, living off the grid, or facing emergencies like storms and natural disasters, a steady power source can make all the difference. From running essential appliances to charging devices and powering tools, reliable electricity is a must-have in many situations.
Traditional generators that run on a single fuel, such as gasoline or propane, have drawbacks: fuel shortages or price spikes can leave you powerless when you need energy most. However, BISON dual-fuel generators solve these problems by allowing the use of two fuels, typically gasoline and propane. This flexibility helps prevent fuel shortages, reduces costs, and improves performance and lifespan.
In this article, we will explore what dual fuel generators are, their benefits, types, key factors to consider before buying, and the best use cases. Whether you’re a homeowner, outdoor enthusiast, or generator dealer, understanding dual fuel generators will help you choose the right power solution.
What is a dual fuel generator?
A dual fuel generator can run on two types of fuel, typically gasoline and propane (or LPG). This flexibility enables dual-fuel generators to provide critical backup power during disasters, power shortages, or emergencies.
They use a fuel selector switch or separate fuel lines to switch between fuels. With a simple adjustment, they know which fuel to burn to generate electricity. Of course, most BISON dual fuel generators have an easy-to-use control panel for switching fuels, along with clear instructions for a smooth transition.
Key components that enable this include:
- Fuel tanks or connections: Separate tanks or hookups for gasoline and propane — gasoline stored in a traditional tank and propane connected via hose to a cylinder.
- Carburetor or fuel system: Specially designed to efficiently handle both fuels, ensuring smooth engine operation regardless of fuel choice.
- Control panel: Contains start/stop buttons, the fuel selector switch, and displays for fuel levels and generator status.
Advantages of dual fuel generators
- Fuel flexibility and availability: Dual fuel generators offer greater adaptability than single-fuel units by allowing you to use whichever fuel—gasoline or propane(LPG)—is easier to find. This flexibility can prevent power outages caused by fuel shortages or price spikes.
- Extended run time: Access to two fuel sources means you can carry both gasoline and propane(LPG) to run longer without refueling. Propane’s long shelf life also makes it ideal for emergency storage. Switching fuels based on conditions helps maximize efficiency and extend runtime.
- Cost efficiency: You can choose the more affordable fuel depending on current prices. Propane burns cleaner than gasoline, reducing engine wear and maintenance costs. Its long shelf life also minimizes fuel waste.
- Environmental benefits: Propane(LPG) burns cleaner than gasoline or diesel, producing fewer harmful emissions like carbon monoxide and particulates. Using propane helps reduce air pollution and lowers your carbon footprint.
- Convenience and storage: Propane’s near-unlimited shelf life makes it safer and easier to store long-term compared to gasoline, which degrades and can damage your generator if stored too long.
- Versatility in application: Dual fuel generators are ideal for emergencies, outdoor activities like camping, and work sites with varying power needs and fuel availability, making them a versatile power solution.
Types of dual fuel generators
Portability dual fuel generators
Small portable dual fuel generators are lightweight and easy to carry, ideal for camping, outdoor activities, or powering essential appliances during an outage. Larger standby generators, on the other hand, are stationary and automatically power your entire home during a blackout, offering reliable, hands-free backup.
Inverter dual fuel generators
These models provide cleaner, quieter electricity that’s safe for sensitive electronics like laptops and phones. They’re also fuel-efficient and typically more compact, making them a great choice for outdoor adventures and travel.
Generators vary in output, measured in watts:
Under 3,000 watts – Best for light use, like charging devices or running a few small appliances.
3,000–7,000 watts – Suitable for powering RVs or covering more critical household needs.
Over 7,000 watts – Ideal for whole-home backup or job sites with high power demands.
Choosing the right dual fuel generator
Key considerations
- Power requirements: Calculate the total wattage of the appliances or tools you plan to run. This ensures you select a generator that meets your needs without being over- or underpowered.
- Fuel efficiency: Choose a model that optimizes fuel use for longer run times and reduced refueling, saving both money and effort.
- Fuel capacity: Fuel tank size affects runtime and power output. Most tanks range from 3 to 8.5 gallons. For example, a 4-liter tank on the BISON Smart Generator Dual Fuel can generate 5.4–20 kWh. A larger tank generally means more output and less frequent refueling.
- Portability: For travel or outdoor use, go with a lightweight, compact model. For home backup, a larger unit may be better. Many heavier models include wheel kits and handles to improve mobility despite their size.
- Noise levels: Noise ranges from 50–90 dB, with most falling between 65–75 dB. Gasoline operation is typically louder than propane. If you’re camping or staying in an RV park, quieter BISON dual fuel generator models are ideal—especially where noise limits apply.
- Runtime: Check how long the generator runs on a full tank of gasoline or propane. Longer runtimes mean fewer interruptions, which is essential during extended outages.
- Ease of use: Look for user-friendly features like simple setup, easy refueling, and digital displays for monitoring fuel and performance. BISON’s Smart Generator Dual Fuel, for example, includes an LCD screen for quick access to fuel levels and operating status.
- Warranty coverage: A reliable warranty demonstrates the manufacturer’s confidence in their product, ensuring peace of mind in the event of a mechanical failure.
Important features to look for
- Starting mechanism: Choose between electric start for convenience or manual recoil for simplicity. Some models also offer auto-start, which is especially useful for powering medical devices during outages.
- Power output options: Look for multiple outlets, including household sockets and USB ports, to support a variety of devices and appliances.
- Safety features: Preference is given to built-in protection features such as low-fuel automatic shutoff, leak sensors, overload protection, and cooling systems to prevent overheating and ensure safe operation.
