What Type of Fuel to Use in Your Generator

Type of Fuel Use in Generator

There are many generator fuel options, and figuring out the most suitable can be overwhelming. The choice may impact the performance, efficiency, power requirements, and when you need to visit a generator maintenance service provider. Consider the distinct characteristics of the available fuels and how they align with your specific needs before settling on one. Here are the types of fuel and the factors to consider when choosing the right option:

Types of Fuel to Use in Your Generator 

There are several types of fuel you can use in your generator. These include:


Gasoline is a liquid fuel from petroleum that produces electricity through internal combustion. It is readily available at most gas stations and easy to store. Gasoline is affordable, with a short shelf life of around 6-12 months. 

Use gasoline for convenience and user-friendliness. Store it correctly and safely to maximize its benefits and minimize risk.


Diesel is an energy-dense fuel from crude oil. It is reliable, efficient, durable, and cost-effective when you want power for longer periods. Store diesel in a cool, dry place, and consult a generator maintenance service provider regularly to run smoothly.

Use diesel to lower operating costs and extend run times. The fuel can be beneficial during prolonged power outages or in remote locations with limited fuel availability. 

Natural Gas

Natural gas is a gaseous fossil fuel composed of methane and hydrocarbons. It is a clean-burning fuel with a lower operating cost. It is virtually unlimited supply when connected to a utility gas line. 

Use natural gas when you have limited fuel storage capacity. You can access a continuous power supply since natural gas is constantly flowing. Consult a generator maintenance service provider for professional installation and reduce the risks at your home. 


Propane is a liquefied petroleum gas (LPG) from natural gas processing and crude oil refining. It is clean and has a longer shelf life of around 18-24 months. Store propane in portable cylinders or larger tanks when other sources are limited. Choose propane when you want a quiet operation. 

Factors to Consider When Choosing Your Generator Fuel

 Choosing the type of fuel for your generator is influenced by various factors. They include:

Type of Generator

Generators accommodate specific fuel types and cater to varying power needs. Portable generators use gasoline or propane, offering flexibility and convenience for on-the-go power solutions or temporary power backup during outages. 

Stationary or standby generators are ideal for permanent installation and provide continuous power backup to homes. These may use natural gas or diesel, taking advantage of their longer shelf lives, lower maintenance requirements, and higher power output capabilities. 

Consider how the generator will be used, the power capacity needed, and the desired level of portability or permanence. Align your fuel choice with the specific type of generator that best meets your requirements to get power solutions tailored to your unique needs.


Consider the initial purchase price and the long-term operating expenses of each fuel. Natural gas and propane often have lower and more stable prices than gasoline or diesel.

Some fuels may require less upkeep, resulting in lower lifetime costs. Assess the various cost aspects of each fuel to make an informed decision that aligns with your budgetary and long-term power needs.
