Dual Fuel Generators vs Gas Generators: Its Uses, Consumption, Pros, and Cons

Dual fuel generators vs gas generators — what’s the difference? Which one is the right option for you? We all have different requirements and needs. Investing in a gas or propane generator ideally depends on what you intend to use it for.  So make sure to read the complete guide below to make your best bet.

Dual Fuel vs Gas Generator: Uses

Uses of Dual Fuel Generator

Usually, a dual fuel generator uses two types of fuels (gasoline and propane) to increase its run time. You can use any of these depending on availability. The higher viability of generators makes them the best option to be used in homes, and other remote sites. Based on your situation, you can switch between fuels and adjust the generator to your needs. Healthcare centers also prefer using top-rated dual fuel for life support machines. They also come in handy in stores. Propane comes in user-friendly containers that make them easy to store. In case you run out of propane, you can always switch to gasoline and run the generator for several days.

Uses of Gas Generator

They are reliable and available everywhere in the world. Natural gas fuel is used by hospitals and other healthcare centers that need a power supply. It is more viable because gasoline has a limited shelf life. Diesel causes environmental pollution and propane fuel sometimes becomes hard to find. Homeowners prefer using this, so they don't have to change the fuel more often. Gas fuel is used as a substitute at places lacking electricity to run electric utilities. Production companies and factories use this fuel, as it provides 90% energy efficiency.

Dual Fuel vs Gas Generator: Runtime

Dual Fuel Runtime

Portable dual fuel generators are available in many sizes, so you can choose the size based on your needs. In a dual fuel generator, you can fill 120 gallons and more fuel at a time. In the case of dual-fuel, a standard propane tank can run for days without the need for refilling.

Gas Fuel Runtime

Gas fuel generators have a pre-installed tank that can only have space for a few gallons of gas. Only a small amount of fuel can be filled in the tanks, so you have to refill the tank to keep your generator up and running.

Dual Fuel vs Gas Generator: PROS

Advantages of Dual Fuel Generator

Following are some major pros of installing a dual fuel generator.

Higher Reliability

A dual fuel generator comes with a lot of convenience and ease. These generators are durable, and allow you to use gasoline or propane fuel. Higher flexibility to choose your preferred fuel ensures an uninterrupted power supply.

More Effective

These generators come with more room for fuel that reduces the need to refill fuel many times a day. It keeps the machine working more times and saves money because it is less expensive.

Switch between Fuels

You can anytime switch to gasoline or propane fuel in emergencies. A dual fuel generator reduces your dependency on one type of fuel. These generators required very little maintenance and you can run them 24/7.


Champion dual fuel generators are designed to withstand natural disasters and other calamities. Their frames are made of steel and study manufacturing reduces the noise. Most of the dual generators have wheels that make them easy to transport.

Advantages of Gas Generator

Following are some major pros of installing a gas fuel generator.

Higher Dependability

Gas Generators are the best choice for both residential and commercial use. This fuel is readily available in stores and gas supply is also accessible in homes. There are also fewer chances of gas fuel running out of supply because its prices don't fluctuate.

Less Expensive

As compared to other types of generators, natural gas generators are more cost-effective. The cost-effectiveness makes them a perfect choice for homeowners. Although the cost of fuel is less expensive, the installation of gas lines can be a bit expensive.


For busy people, it is an ideal option because there is no need to fill the gas.  It automatically comes over the electric utilities whenever required. This is one of the biggest perks of using it over others.


As far as the greenhouse gas emission is concerned, it has the least impact on the environment. Dual fuel and diesel contribute to air pollution. It also reduces soil pollution because it isn't extracted from the ground. For environment-conscious people, natural gas is the safest and more eco-friendly fuel available.

Dual Fuel vs Gas Generator: CONS

Disadvantages of Dual Fuel Generator

Below are some major cons of installing a dual fuel generator.

Lower Portability

The biggest pros of dual generators are that they are heavier than other fuel generators. You have to keep your dual fuel generator linked to the propane tank that makes it hard to move. If you are using propane fuel, the energy efficiency would be lower than gasoline fuel.

More Expensive

As compared to gas fuel generators, dual generators are more expensive. Advanced technology is used which makes it more costly than others.

Higher Complexity

These generators are more complicated to operate than any other machine. Some extra features in them increase the complexity. Customers complain about its complexity, so you should choose a good brand.

Not for small-scale use

The cost of a dual generator is very high, which makes it an unsuitable option if you have low power supply needs. It is a perfect option for industrial use but not always for your homes. It is more convenient to use a single fuel generator for residential use.

Air Pollution

Dual generators use propane and gasoline as fuels, which has a huge ecological impact. It is not an environmentally friendly fuel available.

Disadvantages of Gas Generator

Below are some major cons of installing a gas fuel generator.

Needs a Dedicated Network

Your gas fuel generator needed a pipeline that is also affected by natural disasters. You have to install gas pipelines to supply the gas that is quite an expense. As natural gas is not renewable, its availability in the future is still a question.

Higher Carbon Emissions

Although the eco-footprint is lower, it emits Co2 that is not good for the ecosystem. More than that, natural gas is explosive and increases fire hazards.


In the end, it can be said that both fuels have their perks and drawbacks. Your choice of generator highly depends on your power needs and other circumstances. However, dual fuel generators are a  good option because of their lower cost, higher reliability. If you're someone finding dual fuel generators for sale, see the comprehensive products available.
