Best Dual Fuel Generators Buying Guide For 2023-2024

Now that you have finished reading about all of our picks for the best dual fuel generators, you must know a lot about them.

You also might have considered a couple of options already. But, while choosing a dual fuel generator, you have to thoroughly study its properties and compare its importance regarding your application.

There is a high chance that some features available in a certain product will not be needed in your case at all. To avoid such a problem, we are providing this comprehensive buying guide.

Here, you can read about each of the properties in detail and decide what you need in your dual fuel generator the most. Make sure you read the buying guide completely for accurate selection.

Fuel Capacity:

As dual fuel generators are powered by gasoline and propane, they have dedicated fuel tanks to store fuel. Not all the fuel tanks are the same as each tank has its own capacity. This capacity is given in gallons. For example, a 10-gallon tank can hold 10 gallons or less of fuel at once.

Having a high capacity tank will be advantageous for you in many ways. If you have a large fuel tank, you won’t have to worry about refueling the generator every now and then, and you can enjoy uninterrupted power output. Keep in mind that large fuel tanks are only available with premium options.

Rated and Peak Output:

As you are buying the generator for power backup, you must pay attention to the power available at the output of the generator. You will find 2 different output ratings on each dual fuel generator, which are rated and peak output. But these values differ for gasoline and propane. Therefore, you will find 4 different output values on each generator.

This can get confusing, but you don’t have to worry. If you only consider the peak capacity of the generator for both fuels while buying the generator, you will automatically get a higher running watts output.

For example, if you opt-in for a high peak value for gasoline, you will automatically get a higher peak value for propane and higher running watts as well.

Generator Size:

This can be a major aspect if you wish to move the generator around for different applications. If you are considering a heavy-duty generator, then make sure you take the size and weight of the generator into consideration.

Mostly, heavy-duty generators are bulkier and heavier in comparison with the low powered ones. Hence, moving a heavy-duty dual fuel generator, especially when the fuel tank is full, can be a challenging task.

On the other hand, if the generator is compact in size, you will notice that the power capacity, as well as fuel capacity, will be lower.

Noise Levels:

Dual fuel power generators are powered by internal combustion of gasoline or propane. As this combustion is a continuous process, there is a significant amount of noise produced by generators while they are in operation.

It is impossible to find a fuel generator that is absolutely quiet in operation. But, you can definitely opt-in for a lower noise rated dual fuel generator.

If the generator is making an unbearable amount of noise, it can create a lot of disturbance that will, in turn, affect your application. Hence, you should always consider a generator that has a lower noise rating.

Also, keep in mind that if you are going to use propane as your primary fuel, you won’t have to worry about sound levels as much because propane performs silently.

Engine Efficiency:

Each dual fuel generator houses an engine that is used to burn the gasoline or propane to generate energy. While many power output ratings might seem similar, the fuel consumption will change because of engine efficiency.

The engine efficiency basically represents how efficiently the fuel can be consumed to produce energy.

If the engine is not efficient, you will run out of fuel pretty fast. Also, you will face a lot of harmful exhaust gases caused by the improper burning of the fuel. Hence, even if you are going for a low power engine, make sure that it is efficient in terms of fuel consumption.

Conclusion:

A dual fuel generator can be a lifesaver if there is a sudden power cut. The major advantage of a dual fuel generator is the option to use a secondary fuel in case you don’t obtain the primary fuel around you.

There are a lot of different dual fuel generators available in the market. Hence choosing one of them can be a tedious task.

Therefore, we have created this list of the best dual fuel generators for you. You can also find a buying guide to help you with your purchase.

In case you are still wondering which one of the above options is the best for you, you can take a look at our recommendations below:

At first, we will recommend you Westinghouse dual fuel generator as a heavy-duty option. This generator is capable of providing 9500W of continuous power and it has a 12500W peak power capacity.

The fuel tank is pretty big as it can hold up to 6.6 gallons of fuel at once. You will get 3 year of warranty with this model.

If you need a decent collection of outlets, then the Pulsar dual fuel generator will be a good choice. It also has a good power ratings as it can provide up to 9500W of continuous power and it has a 12000W of peak power.

The fuel tank is also large at 8 gallons. But you will get only 1 year of warranty from the manufacturer on this generator.
