3 Best Dual Fuel Generators

This article will cover what are dual fuel generators, what separates them from conventional generators, and review the best dual fuel generators.

 

We will also look at their pros and cons to help you decide on the right dual fuel generator for your needs.

 


What is a Dual Fuel Generator?

A dual fuel generator is a multi fuel machine that produces electricity from gasoline or propane. They have been specially engineered in a way that their engines can be powered by the alternate source of fuel in the case one is not available.

 

This model of operation is supported on the standing that both fuels do not mix in the course of operation. With that, you can always have two separate tanks holding different fuels, or one with the available fuel in case the other is suddenly not available.

Check Latest Price

Founded in the year 1886, Westinghouse has lasted this long in the market just because they know what they are doing. With their WGen7500DF, they have cemented that stand even further.

 

Additionally, the Westinghouse WGen7500DF boasts an impressive 10 hours of operation when maintained on its fuel sources, cranking out as much as 7500 watts of energy in the least. Yes, that is the least – since the machine can manage up to 8550 watts when it is being run on the propane fuel tank.

 

Speaking of the tanks, this unit is built with a sturdy frame which has metal roll bars incorporated into them. These roll bars are arranged in such a way that they provide additional protection for the fuel tanks.

 

Likewise, they make it easy to lift the generator when transporting it from one place to the other is needed.

 

To cap it all off, the unit is protected by a voltage regulator. This is in addition to the low shut off oil sensor and a couple of other safety measures in place. Together, they ensure the engine is never overloaded to the point where it causes a fatal damage.

 

PROS

  • Digital hour meter on the unit helps in scheduling maintenance
  • Can crank up between 7500 – 8550 watts of energy during operation
  • Comes with everything you need in the box – manual, funnel, tool kit, etc.
  • A remote start is possible by a key fob
  • Lower fuel consumption due to the overhead valve technology
  • Fuel selector switch is easy to operate
  • Circuit protection and low-oil shutoff switch for better engine safety

 

CONS

  • Does not come with a battery
  • Engine oil doesn’t ship with the unit
  • The propane tank is not included in the pack

DuroMax XP10000EH

DuroMax XP10000EH Dual Fuel Portable Generator - 10000 Watt Gas or Propane Powered-Electric Start- Home Back Up & RV Ready, 50 State Approved

Check Latest Price

Are you looking for a generator that needs a lot of power? The 10,000 watts of energy that this Duromax XP10000EH is capable of might do the trick.

 

For all that power, one would expect that the unit groans, huffs and puffs when working. In fact, the opposite is the case.

 

You would think so too if you knew that only about 72 dBA of noise is always produced during operation.

 

If you have been looking for a generator that packs electric start functions out of the box, this is yet another one to look at. That is not to mention the obvious – the fact that the Duromax XP10000EH runs on both gasoline and propane.

 

Speaking of the fuels it runs on, we believe it does so quite efficiently too. Even though Duromax might not be known for great customer service, this unit still comes with a one-year warranty. If you can look past that, though, you would totally enjoy the versatility provided by the six outlets on the generator set.

 

Starting the unit is as easy as turning a key. However, this might fail when a battery is not in the machine, or dead. To cater for such situations, Duromax has installed a coil starter into the unit.


Of course, we would expect something that could generate that amount of energy to be heavy. A total weight of 256 pounds is no small deal, but solid wheels and handles will make you forget that during transport.

 

With all the power coming from a massive 4-stroke engine and the potential to clock up to 18 HP, this generator can power most homes and some industrial setups in the case of a power outage.

 

PROS

  • Comes with a huge engine that generates lots of power
  • Noise levels are surprisingly low
  • A total of six outlets makes the generator highly versatile
  • Easy two fuel selector switch

 

CONS

  • Surge protection is absent
  • Duromax is not known for stellar customer service

Why Should You Get One of These?

Buying a dual fuel generator could be worth it as it allows the versatility of producing power from gasoline or propane. This allows you to choose the most available or affordable fuel source.

 

The option to use propane as fuel allows for a cleaner burn than gasoline, which is safer for the environment and better for the generator as well.

 

However, dual fuel generator’s run time, noise levels, and portability are not necessarily better than single fuel generators although they cost around $100-$200 more.


So, Which is Best?

All of these dual fuel generators have their pros and cons. But, which is best? There is no one-size fits all answer because it will depend on your specific needs. Each generator has different specialities.

 

Performance

The Champion 4250 is the best performing option with 4,250 peak Watts and a run time of up to 22 hours hours on gasoline at 25% load.

 

Price

The Champion 4250 is also the most affordable option

 

Portability

The Westinghouse WGen 7500DF is the most portable option and comes with wheels and a foam grip handle included.

 

Safety

The Westinghouse WGen 7500DF also has the best safety features including low oil shutdown, and twist lock/rubber covered outlets. This generator is also CARB compliant meaning its safer for the environment than some other options.

 

Noise

Inverter generators tend to be more quiet than conventional generators, and that’s the case here as well because the Champion 4250 is the most quiet option at only 64 dB.
