Dual Fuel Generators

Dual Fuel Generators For Sale

Dual fuel generators have become a go-to solution for homeowners, contractors, and businesses seeking dependable power that adapts to changing fuel availability. By running on two different fuel types, typically propane and gasoline, these units provide the resilience, cost control, and runtime flexibility needed for emergencies, worksites, and recreational use.

What Is a Dual Fuel Generator and How Does It Work?

A dual fuel generator is designed to operate on two distinct fuel types — most commonly gasoline and propane. The engine and fuel delivery system are built to allow seamless switching between fuels, often via a simple selector switch.

Gasoline delivers high energy density and is widely available, while propane offers a cleaner burn, longer storage life, and stable performance in cold conditions. Inverter dual fuel generators provide cleaner electricity for sensitive electronics, while conventional models prioritize maximum output.

Advantages of Using a Dual Fuel Generator

Dual fuel generators deliver unmatched flexibility, making them valuable for situations where fuel choice and runtime matter most.

They extend operating time by allowing you to switch fuels when one runs low, keep you operational during fuel shortages, and help control costs by letting you choose the cheaper fuel option. This flexibility is particularly important in storm-prone regions, remote worksites, and off-grid travel.

Potential Limitations to Consider

While highly versatile, dual fuel generators have trade-offs. They are generally heavier and more expensive than single fuel models due to the added components. Propane may deliver slightly less power output per gallon than gasoline, and operators must understand safe handling procedures for both fuel types.

Fuel Efficiency and Runtime — Propane vs Gasoline

*Costs vary by region and market prices.
**Propane shelf life is effectively unlimited if stored in a sealed cylinder.

Choosing the Right Dual Fuel Generator for Your Needs

Selecting the right model starts with determining your wattage requirements. For home backup, ensure the unit can handle your essential circuits and, if possible, integrate with a transfer switch. For worksites, prioritize fuel efficiency under continuous heavy load and robust construction. For RV and camping, choose an inverter model for quiet operation and clean output.

Maintenance & Safety for Dual Fuel Generators

Maintaining a dual fuel generator requires following both gasoline and propane care guidelines. Gasoline tanks should be treated with fuel stabilizer or drained if storing long-term, while propane hoses and connections should be inspected for leaks.

Always operate outdoors or in well-ventilated spaces to prevent carbon monoxide buildup, and store fuels according to local safety regulations.
