Best Tri Fuel Generators 2021

tri-Fuel generator is a type of portable generator that could run on three different fuel sources, namely NG, or natural gas, Propane or Liquid propane gas and Gasoline.


The reason for generating electricity using multiple sources becomes useful when one type of fuel source may not be available during an emergency, power outage, severe snow, etc. Fuel flexibility is beneficial in many different ways. You can be sure that the portable generator works during fuel shortages and keeps your generator on when the power is out, even if you have only one or two fuel types on hand.


The best Tri-Fuel Generators should have the following features- triple fuel capabilities, sufficient fuel capacity, excellent run-time, and of course, reliability. In addition, the tri-fuel generator should be able to accommodate the fuel you have on hand when typhoons, hurricanes, or when the power grid goes down, and you need electricity.

Frequently Asked Questions (FAQs)

Are these Natural Gas Portable Generators?

Yes, most of the generators mentioned on our list use three fuel types (Natural Gas, Propane & Diesel). However, these generators have slowly been replaced by dual fuel generator types on the market as they are more efficient and safe for use. We also recommend the later kind of generator for users that want to pick up a new unit from the market.


If you have any problem picking up the ideal model for your needs, you can always use the contact page, and we will get back to you.


What Fuel is Most Efficient For Tri-Fuel Generators?

When it comes to generator fuel, diesel is hands-down the most efficient option. Because of this, you will save money on diesel compared to using alternative fuels. However, depending on local diesel pricing, diesel can potentially be the most cost-effective fuel in particular situations.


Unfortunately, diesel is usually missing from a tri-fuel generator’s fuel system. Propane, natural gas, and gasoline have all been tested, with gasoline coming out on top. Propane, on the other hand, is typically less expensive per gallon and you can easily connect your generator to a propane tank. A few disadvantages of using gasoline include the difficulty of obtaining and storing it, as well as the fact that it burns less cleanly.


When compared to natural gas, propane has a burn efficiency roughly two times greater. However, natural gas is less expensive per unit than propane, which is the case for both liquid and gaseous fuels. To choose the most affordable option, look into local fuel prices and energy efficiency first. Keep an eye on fuel prices to see if you can get a better deal in the future.


Regardless of how efficient or affordable it is, natural gas is preferred by many households. A natural gas-powered generator can run endlessly without the need for manual refueling. For some, the added cost is well worth the added convenience. To avoid personal injury or damage to your underground pipes, have a professional connect your generator’s gas lines.


Do I Really Need a Tri-Fuel Generator?

In many cases, but not all, tri-fuel generators are the best option. Standby generators have various advantages that portable tri-fuel generators do not. As an example, the power of a portable generator cannot match that of a standby generator (particularly one powered by a tri-fuel). So they aren’t able to run all of your electronics at once.


Owners of tri-fuel generators should be prepared to use a variety of power sources. A tri-fuel generator isn’t necessary if you only ever use gasoline. Some homeowners choose not to have their generators’ connected to a natural gas line. A single- or dual-powered generator may be less expensive if this is the case. Those that need a variety of power sources can benefit from tri-fuel generators, which are designed for those who know they will need them.


Can I Hook Up Natural Gas From My House To My Generator?

You can hook up your generator to the natural gas line, however, you can only achieve this if you are either using a tri-fuel generator or converting your generator to natural gas. The generator will also need to be close to your house, and you will need to have a gas meter outside of your house.


Can I Convert a Dual-Fuel into a Tri-Fuel Unit?

Yes, you can convert a dual fuel generator and a single fuel generator, If you already own a dual-fuel generator, converting it to a tri-fuel generator will not require any major modifications. You simply add an additional fuel tank and change over the wiring connections so that all of them connect together. If you decide to go DIY, there are many conversion kits and tri fuel kit online that can help you safely convert your generator.


However, if you don’t understand the dynamics of mechanical parts, it might come as rocket science. In that case, you will need a handyman for the conversion. Below we recommend a fitting tri-fuel conversion kit for all kinds of models.


As mentioned, tri fuel generators tend to be hard to find and are often out of stock. However, the Sportsman 4000 Watt Generator is a great tri fuel generator and is currently in stock and available.

Alternatively, we recommend the following dual fuel generators:

  1. DuroMax XP13000HX
  2. Durostar DS10000E
  3. Westinghouse WGen9500DF
  4. Champion 100573 4000W

Before selecting the best Tri-fuel generator, it helps to determine how you’ll be using the generator and what devices or appliances you’ll be powering up with it.

Also, you’ll want to make sure you’re not breathing in any poisonous exhaust fumes.. so we would suggest checking out an Exhaust Extension for your generator.

All of the options above will be sure to give you the electricity you need during times of emergencies or when the grid goes offline. What’s more, you get peace of mind knowing that the generator can be relied upon to work when needed. Still haven’t found the product you are looking for?
