Generators are an essential tool that provides power supply when there is a limited supply of electricity, or during a power outage.

This is a great investment for homeowners and even for commercial uses that are supporting many powered devices. There is no need to worry when there is a power interruption within the area if a generator unit is set.

A generator comes in different types and models to satisfy every household’s needs. That includes dual and triple fuel generator types, which obviously work in a different way.

It is unlike solar generators that operate with the sun’s energy but through a variety of fuel sources that differ in price and availability.

Having a generator unit for commercial or household use is a great investment these days. It might be costly initially, but worthwhile in the long time run.

Experts can assist you in getting the right generator model for your specific needs. This post can also be beneficial for first-time buyers looking for the best generator unit in the market.

What is a Tri Fuel Generator?

What is a Tri Fuel Generator

A tri-fuel generator is a type of generator that operates with three fuel options, such as propane, gasoline, and natural gas.

It is portable and highly suitable for a variety of applications. People choose to buy a tri-fuel generator with an anticipation of having a wider choice of fuel sources.

It can power your home and other spaces during a power outage, especially this summer season.

Triple-fuel generators allow users to pick one of the fuel sources based on budget and current needs. They feature versatility when it comes to delivering more efficient energy for the household.

Is One Fuel Type More Efficient?

When it comes to running a generator, fuel type can make a difference. One fuel type generator can be efficient depending on the user’s intent to use the unit.

For instance, if you are in a hurricane-prone area, a dual fuel generator is highly recommended. It can deliver more energy than a single fuel unit when there is a limited supply of power, especially when a disaster strikes.

Each fuel option is made to meet different needs of power energy. Propane, for example, can last longer and won’t go bad, unlike gasoline that can only last for at least a year.

Having an idea of many good fuel options can show you which one is efficient for your needs.

The availability of that one fuel type for your current needs is also essential to know. This would prepare households in times of tragedy to make a generator unit efficient.

Which Fuel Is Most Efficient?

Before you decide which fuel generator to buy in the market, you must identify the most efficient and convenient fuel source for the unit.

Today’s market has claimed that the diesel option can power up a generator with the highest energy efficiency.

It is also affordable and widely available in local areas, making diesel one of the most bought fuel sources for generator units.

However, it could be hard to look for tri-fuel generators that work with diesel. These units use up other energy-efficient fuel options, such as natural gas, propane, and gasoline. They differ in prices and availability that buyers might also keep in mind.

The next thing is to find out which of these three fuel choices is the most efficient. Below is a brief explanation of each option to help homeowners decide.

Which Fuel Is Most Efficient?

Natural Gas

Natural gas enters a generator unit through a flexible hose and a low-pressure generator to begin working.

It is a convenient choice among the fuel sources because refueling can be ignored. Just make sure to have an endless supply of natural gas to keep the generator unit operating.

Hire a professional to build gas lines into the generator unit to avoid harming yourself.

Another advantage of using natural gas on generators is it is safe for the engine. It is a clean-burning fuel but will not leave any residue in the engine as gasoline does.

The fuel source increases the lifespan of the generator’s engine with less maintenance required.

Therefore, natural gas is efficient as well as good for the environment for longer uses. Many people prefer using natural gas despite its efficiency due to the convenience it provides.


Gasoline is another efficient fuel source for tri-fuel generators. The disadvantage is that gasoline is not long-lasting which can be stored for future uses.

It is also not easy to obtain and a bit pricier per gallon than the other fuel sources.

Gasoline can also be smelly during the operation. The emission of gas would be dangerous to human health, as well as to the environment.

LPG (liquefied petroleum gas)

This is also called propane. It is believed to be the most efficient of all the fuel sources for generator units.

Propane can be stored for longer periods and is easy to find in most hardware stores and propane suppliers. It is also less expensive but the price may vary in your area, so better check them out.

Homeowners can purchase either smaller or larger tanks depending on their needs. The buying decision will agree on how often you refuel the generator unit.

To go with a larger propane tank is highly advisable because of its extended lifespan.

Similar to natural gas, propane is a clean-burning fuel that is best for engines. It will surely leave the unit clean that would extend its useful life in delivering a power supply.

How Much Upkeep for Portable Tri-Fuel Generators

Internal combustion systems do require regular maintenance to deliver more accurate services, such as through generators.

The maintenance process will include the fuel delivery, air filter, lubricants, and the engine’s ignition.

There are many other factors to consider on each part, such as the type of fuel, the motor’s age, and the manufacturing.

The maintenance schedule may vary according to the times of use for a generator unit. Those generators that function for intermittent use only will have a different schedule than those frequently used units.

Generators that operate only once a year are more difficult to maintain. There should be a weekly test run cycle to diagnose problems right away over the unit.

Here are the two things homeowners must monitor in conserving a generator unit:

Type of Fuel

Since fuel is subject to evaporation and can eventually emit dangerous chemicals, it is important to store it in a safer place.

Thankfully, most of the generator units are equipped with fuel injection systems that can keep liquid fuels away from evaporating.

One more thing is that liquid fuels may cause some degree of lubrication that requires proper maintenance to prevent rusting.

Gaseous fuel options are less of a problem because of their heavier components.

Unlike liquid fuels, they are not subject to evaporation due to the absence of lubrication properties. Therefore, it demands lesser maintenance costs.


All kinds of engines demand a service. The only difference is that gas-powered engines are expensive in the first place but will require the least maintenance.


It is highly recommended to do a regular test cycle to ensure all parts are working well. If there is a power failure, automatic cut-over can help to sustain the generator unit.

Most generator models also feature automatic diagnostics for a more convenient upkeep process. Generator owners must also change the oil and air filter when necessary to avoid rust.

Gas-powered generators require more upkeep and care than other fuel models. – absolutegenerators.com

Is A Tri-Fuel Generator Right For Me?

Tri fuel generators may be fit for your needs but not for everyone. They are portable and may lack some of the good features of stationary generators.

An example is the power capacity of a portable generator which can be lesser than the standby generator models. It could not accommodate all of the home devices that need power during an outage.

Moreover, tri-fuel generators also demand multiple power sources and so an added cost for homeowners. They are suitable for households who are certain in using not just gasoline to power it.

The tool can be connected to gas lines for more power options. If this is not your primary need in buying a generator, better go for a single or dual fuel generator unit to save up cost.

Final Thoughts

Wrapping it all up, a generator unit is one of the most helpful tools during these digital times. We spend so much time-consuming power and when an outage occurs, everything seems useless.

A tri-fuel generator has stepped up the game with all of its unique features. It can run on multiple power sources depending on fuel readiness, unlike single fuel generators. Lastly, it is highly efficient for a wide application.

Find out the best brands and models of dual or tri-fuel generators in today’s market.
