Find The Best Generators of Each Fuel Type

Want to find the best generator for each fuel type? From Diesel, Gasoline, and Propane to Natural Gas and Solar power, we got it for you.

Things You Need To Know First

Generators are a very useful addition to our lives. They are good investments for future emergencies such as power outages. Office, apartment or even in an average home, generators will always be useful in an emergency.

Generators serve as backup power. In fact, sometimes they are the only source of power for certain activities such as camping, tailgating and the like. What’s important for you to know is that aside from the different types of a generator (conventional and portable), there are also different gas-powered generators.

Some generators are classified by their fuel type. Finding the best generator for each fuel type requires you to check their pros and cons. Today, we will be talking about generators powered by diesel, gasoline, propane, natural gas and solar power.

Here are several things we think you need to know!

Best Diesel Generator

Features

To find the best portable diesel generator or the best diesel generator in general, you need to look into their features. There isn’t much difference in features when it comes to generators per fuel type.

However, there are very few features depending on the brand and generator model that sets them different from the rest. For instance, generators have different safety features. The most common safety feature is a circuit breaker protection.

This helps keep you and your generator from electric shock and/or overloading. A low oil shutdown feature is also a good addition. This feature automatically shuts down the engine upon detection of low oil pressure thus, lessening potential engine damage.

What To Look For

Top diesel generator reviews can help you know what to look for when buying. However, there is only so much knowledge reviews can give you. What you need are first-hand information and parameters.

First when buying a diesel generator, you have to check its power, performance, and capacity. Diesel generators are very sturdy and do not require too many features, which is why these three are among the most important aspects.

Does it have an 8-gallon fuel tank capacity? What is its running and starting watts? Is it equipped with a USDA approved spark arrestor/muffler? Can the engine withstand the rigors of long operation?

These are just some of the most important questions you need to ask before buying a diesel generator.


Pros

  • Diesel generators are very low maintenance and fuel efficient. In fact, they can even run for years without maintenance.
  • Again, diesel generators can provide more horsepower per fuel gallon in comparison to gas-powered generators.
  • Diesel generators are very durable. They are sturdy enough to withstand regular wear and tear.
  • Diesel is the most efficient generator fuel and the safer option to store for longer time periods compared to gasoline. This is because diesel requires a higher temperature to ignite.

Cons

  • If not used regularly, diesel generators tend to break down.
  • Diesel generators are significantly more expensive than most gasoline-powered generators.
  • Diesel fuel that is stored for too long can potentially damage or degrade the workings of your generator engine.

Best Gasoline Generator

Features

The best-rated gasoline generators are equipped with highly functional and straightforward features. Gasoline generators are not usually fuel injected, unlike diesel generators.

Contrary to the diesel generator’s direct injection fuel engine, a gas-powered generator features an OHV engine. They also have different throttle modes that increase fuel economy and keep the engine from constantly running at full speed.

And when it comes to portable gas-powered generators, you will commonly find models that have good inverter technology. Good inverter technology produces very little THD (total harmonic distortion), thus, a cleaner and more stable power output, suitable for even the most sensitive devices and appliances.

What To Look For

When in doubt, you can check the best generator reviews for reference. However, the most important thing is you know what you’re looking for. You should know what you need from a generator.

For gasoline-powered generators, those that come with features to improve fuel economy are highly idea. This is because gasoline is not as fuel efficient as diesel. A fuel stabilizer is also a good addition when buying a gasoline-powered generator.


Pros

  • Gasoline is a fairly common type of fuel. It is very accessible among local gasoline stations, making it easy for you to refuel your engine.
  • Gasoline-powered generators are relatively cheaper compared to other models.
  • Gasoline tends to be more fuel efficient compared to propane and/or natural gas.

Cons

  • Gasoline has a very short shelf life. This fuel type can easily break down or start absorbing moisture within a month’s time.
  • Gasoline has a lower flash point of temperature making it easy to ignite and cause a fire when stored somewhere a little hot.
  • Gasoline-powered generators tend to require more expensive.

Best Propane Generator

Features

Propane generators are also referred to as liquid propane or liquid petroleum gas-powered generators (LPG). However, what makes this type different from other fuel type generators; it runs on a tank separate from the generator itself.

This LPG tank can be the same tank you use for grills, fueling heaters and/or the like. Or, you can opt to use a stationary tank that you can simply via a service truck from time to time.

This type of generator is perfect for recreational purposes such as camping, RV power, or even emergency backup power.

What To Look For

The best propane generators are not always the one with the most features or the highest fuel tank capacity. However, it is very important to take note of the fuel capacity of your propane generator.

Check if it accepts a 20lb or 30lb LPG tank and so on. You cannot hastily buy an LPG tank and assume that it will be accepted by any propane generator model. Also, look at the durability of the generator from the engine to its frame or enclosure.

This is to make sure that your generator will be sturdy enough to withstand wear and tear or the rigors of a long operation.


Pros

  • The propane type of generator and the LPG tank are both fairly accessible and easy to buy.
  • This is the best generator option for you if you are not planning to use it as often.
  • Again, it is highly ideal for recreational purposes and outdoor activities such as camping, RV power, and even home backup power.
