Generator Fuel Types

Let’s take a look at different generator fuels now that we’ve covered the finest dual-fuel generators. Knowing the multiple kinds offers you a better understanding of which fuel to use and which is most convenient for you.

We’ll look at the different types of fuel and their benefits and drawbacks so you don’t have to. Let’s get this started!

Generator Fuel Types

Before we get into the pros and cons, it’s important to note the fact that is, there are just three types of fuels to be aware of. The three most crucial ones to understand are propane, gasoline, and diesel.


If you’re searching for the most efficient, diesel is the greatest option. Increased piston pressures and related higher temperatures cause the engine to operate harder while using less energy. Furthermore, diesel is well-known for its reliability, which is why so many people choose it. 

Diesel is most likely to be found anywhere in town, and the price is unaffected by other circumstances. The downside is that one will not be rewarded for maintaining a clean environment. Diesel generators are notorious for their high carbon emissions.


If you’re searching for an eco-friendly badge from your commissioner, this is the one to utilize. Gasoline is mostly made up of methane, which ensures that it burns cleaner than other fuels. They are also less expensive than other alternatives.

However, if you wish to use it at a workplace or anything else that requires consistent electricity, gasoline generators are not the best option. Because you can’t keep that gasoline in your fuel tank every time, you’ll need some time to regain power because you’ll have to manually refill it.


Propane is indeed the safest option out of every one of them. To begin with, it burns cleanly, meaning you won’t be harming the environment. Second, you have unlimited time to retain it. This is the ideal solution when you’re not using your generator regularly because it has a long expiration date.


The only drawback is that this is inefficient. You probably wouldn’t get a lengthy runtime with these fuels because they burn sooner than the others.

Recoil Cord vs. Electric Start

Different starting methods are frequently seen in the generator industry. Some of them are electric, while others follow recoil protocols. There is also a remote start option, which allows you to start from a certain distance. 

However, even if the generator has a remote starting system, you will see that these two start systems are always present in the generator. It’s primarily due to reliability.

Recoil Cord vs. Electric Start

However, there is still some misconception about the differences between recoil and electric start, so we’ll explain.


After you buy a recoil start generator, you will notice a small grip point attached to the side of the generator. To start your generator, begin drawing it, and you will see a wire as soon as you begin pulling it. 

The engine will start if you keep it tugging for a few seconds. This is one of the most reliable starting methods since the starting mechanism relies on the kinetic energy you provide.

Electric Start

Having a generator that follows the electric start method is as simple as turning on a light. To turn it off or on, all you have to do is flick the switch up and down. However, there are two different sorts of electric start systems.

The first is the custom-built compartment in which the toggle switch is installed. Your switch is located in a separate section in the generator, where you can quickly turn it on and off. The second is on the generator panel, where you may view your generator’s stats. You’ll see a dial slot on the panel where you may start your engine by toggling it.

Does Honda Make Dual Fuel Inverter Generator?

Despite their reputation for being the finest engines ever, Honda does not produce dual fuel inverter generators. To ensure that their powerful engines do not go to waste, they have partnered with a few brands that utilize Honda engines.

Furthermore, by following a few simple steps, you may convert your generator to work on a Honda engine. 

Does Honda Make Dual Fuel Inverter Generator

Nonetheless, switching to Honda engines is a good idea. They are more efficient than conventional generators and burn cleaner, which is beneficial to engines. Honda engines also require far less maintenance due to their robust nature.


In this section, we have compiled a list of commonly asked questions about generators and their insights. Let’s get this class going!

Why Dual-Fuel Inverter Generators are Better? 

It’s primarily about the flexibility of being powerful enough to run over both fuels instead of only one. If one sort of fuel is unavailable, you may be will obtain the other. In addition, a dual-fueled inverter generator is recognized for delivering renewable energy that is beneficial to your gadgets.

How does a dual fuel inverter generator work? is it worth it?

Dual inverter generators might be investigated further. You just turn the knob to inform the engine to operate on that specific oil. On the other hand, people have had the alternative of using a generator for more versatility.

Is it cheaper to run a generator on gasoline or propane?

Although gasoline is less expensive to purchase, propane is far more cost-effective in the long term. Because we don’t use generators very often, storing propane is simply more convenient.

Can you run a dual fuel inverter generator on natural gas?

Yes, since the engines are compatible, you might want to use natural gas as per dual fuel inverter generator reviews. While some can run on energy resources without a problem, others may need major changes.

Can a dual fuel RV inverter generator run a refrigerator?

It makes no difference if your generator is dual fuel or inverter. Only the watts required by your refrigerator and the running watts of your generator are important. If it’s more than double, you will be well running a refrigerator.

Does Briggs and Stratton make a dual fuel generator?

We don’t know for sure right now. Although Briggs & Stratton manufactures portable generators, we were unable to locate a dual-fuel one.

Final Words

Generators are an expensive purchase, and hence you should do it right the first time. This was the 10 best dual fuel inverter generator from our expertise. However, to find the one that suits you best, you should always consider your environment and mainly what fuels you’re willing to operate them at.

Hope we were able to answer your concerns, and it’s okay to be extra peculiar when making a big purchase. And with this, we hope you find exactly what you’re looking for.

Till next time, enjoy your day and be conscious of fuel usage!
