Introduction: The Rise of Dual Fuel Generators

In recent years, dual fuel generators have surged in popularity. The ability to run on both gasoline and propane (and sometimes natural gas) offers users flexibility, longer run times, and the security of having a backup fuel source during emergencies. This versatility is especially valuable during natural disasters, camping trips, or extended power outages when one type of fuel may be scarce.

As a result, many leading generator manufacturers have introduced dual fuel models to their product lines. Brands like Champion, DuroMax, Westinghouse, and Firman now offer a wide range of dual fuel portable generators. Given Generac’s reputation for quality and innovation, it’s natural for consumers to wonder if Generac has joined this trend.

What Is a Dual Fuel Portable Generator?

A dual fuel portable generator is a generator designed to operate on two different types of fuel, most commonly gasoline and propane (LPG). Some advanced models can also run on natural gas. The key feature of a dual fuel generator is its ability to switch between fuel sources, either manually or automatically, depending on the model.

Key Benefits

Fuel Flexibility: Can run on either gasoline or propane (and sometimes natural gas).
Extended Run Time: Switch between fuels for longer operation.
Cleaner Operation: Propane burns cleaner than gasoline, producing fewer emissions.
Storage Benefits: Propane can be stored indefinitely, while gasoline degrades over time.

Generac: A Leader in Power Generation

Founded in 1959, Generac Power Systems is an American manufacturer specializing in backup power generation products. Generac is best known for:

Home Standby Generators: Market leader in whole-house backup systems.
Portable Generators: Wide range of models for home, job site, and recreational use.
Inverter Generators: Clean, quiet power for sensitive electronics.
Commercial and Industrial Solutions: Large-scale backup and prime power systems.

Generac’s reputation is built on reliability, innovation, and a commitment to meeting the evolving needs of consumers and businesses.

Does Generac Make a Dual Fuel Portable Generator?

The Short Answer

As of 2025, Generac does NOT manufacture or sell a dual fuel portable generator in their consumer product lineup. All Generac portable generators are designed to run on a single fuel source—either gasoline or, in some cases, liquid propane (LP)—but not both.

Details

No Factory Dual Fuel Models: Generac’s official product lineup, both in the United States and internationally, does not include any dual fuel (gasoline/propane or gasoline/natural gas) portable models.
No Official Conversion Kits: Generac does not offer or endorse any factory-approved dual fuel conversion kits for their portable generators.
Warranty Implications: Modifying a Generac generator to run on a second fuel using aftermarket kits will void the manufacturer’s warranty.

What About Standby Generators?

Generac’s home standby generators (such as the Guardian series) are designed to run on either natural gas or liquid propane, but these are not portable and are intended for permanent installation.

Why Doesn’t Generac Offer Dual Fuel Portable Generators?

There are several possible reasons why Generac has not introduced a dual fuel portable generator:

1. Engineering and Emissions Standards

Generac is known for its strict adherence to quality, reliability, and emissions standards. Designing a generator that meets Generac’s high standards for performance, durability, and emissions on both gasoline and propane is a complex engineering challenge.

2. Brand Reputation

Generac’s reputation is built on reliability and longevity. Introducing a dual fuel model that doesn’t meet their exacting standards could risk damaging their brand image.

3. Market Focus

Generac’s primary focus has been on home standby and commercial generators, where dual fuel capability is already offered (natural gas/propane). Their portable line has traditionally emphasized gasoline or dedicated LP models.

4. Aftermarket Solutions Exist

Many third-party companies offer dual fuel conversion kits for Generac generators, allowing users to modify their units if they desire dual fuel capability.

5. Strategic Product Development

Generac may be waiting to see if the dual fuel trend is a lasting shift or a temporary fad before investing in new product development.

Generac’s Current Portable Generator Lineup

Generac offers a wide range of portable generators, including:

1. GP Series (Gasoline Only)

GP2200i, GP3500iO, GP6500, GP8000E, etc.
Designed for home backup, camping, and job sites.

2. IQ Series (Inverter, Gasoline Only)

iQ3500, iQ2000, iQ2300, etc.
Quiet, clean power for sensitive electronics.

3. XC Series (Gasoline Only)

Heavy-duty models for professional use.

4. LP Series (Propane Only)

LP3250, LP5500, etc.
Designed to run exclusively on liquid propane.

None of these models are dual fuel.

Alternatives: Top Dual Fuel Portable Generator Brands

Can You Convert a Generac Portable Generator to Dual Fuel?

Aftermarket Conversion Kits

While Generac does not make dual fuel portable generators, aftermarket conversion kits are available from third-party companies. These kits allow you to modify a Generac generator to run on propane (LPG), natural gas, or both, in addition to gasoline.

How Do Conversion Kits Work?

Carburetor Adapter: The kit typically includes an adapter that fits between the air filter and carburetor, allowing propane or natural gas to mix with incoming air.
Regulator and Hoses: A regulator controls the flow of propane or natural gas from the tank to the generator.
Selector Valve: Some kits include a valve to switch between gasoline and alternative fuels.

Popular Conversion Kit Brands

US Carburetion
Hutch Mountain
Motor Snorkel
Century Fuel Products

Compatible Generac Models

Most conversion kits are designed for popular Generac models such as the GP and XP series.

Risks and Considerations

Warranty Voidance: Any modification, including installing a conversion kit, will void Generac’s warranty.
Safety Concerns: Incorrect installation can lead to fuel leaks, fire hazards, or carbon monoxide poisoning.
Performance Issues: Generators typically produce less wattage on propane than gasoline.
Legal and Insurance Issues: Some jurisdictions prohibit or restrict modified generators. Insurance may not cover damages from a modified generator.
Emissions Compliance: Modified generators may not meet EPA or CARB standards.

Pros and Cons of Dual Fuel Portable Generators

Pros

Fuel Flexibility: Use whichever fuel is available or more affordable.
Extended Run Time: Switch between fuels for longer operation.
Cleaner Operation: Propane burns cleaner, producing fewer emissions.
