What I
s The Best Generator Fuel?
A major consideration for any generator purchase is which fuel type or types would best meet the buyers’ power generation needs? Most home generators and portable generators are powered by unleaded gasoline, diesel, propane, or natural gas. Some generators, such as dual fuel generators and tri fuel generators, can be powered by two or all three fuel types. Read below to figure out which fuel types and generators may be right for you.
Unleaded Gas
Advantages
Unleaded Gas is a great fuel option because of its wide availability. Just go to your local gas station, fill-up a 5-10 gallon container, and you are set. Unleaded gasoline is also portable which makes it a great option for those looking to be more mobile and portable with their generator. There is no large propane tank to contend with.
Disadvantages
Unleaded gasoline is less efficient than natural gas or propane. Further, gas may not be readily available during power outages and disasters such as hurricanes, floods, tornados, and blizzards. Gas is also highly flammable and storing large quantities of fuel may be hazardous. Unleaded gas has a shelf life of about 1 year so long-term hoarding of gas is not a good solution.
Recommendation
Unleaded Gas is a reliable fuel source and is most often widely available. It maximizes portability of a generator. Be smart about how you store it and consider it a viable fuel option. See our article Best Small Gas Generators. See gas generators for sale.
Diesel Fuel
Advantages
Diesel fuel is strong in areas where unleaded fuel lacks. Diesel fuel is the least flammable fuel source and is more easily obtained during natural disasters. Diesel generator engines are designed for high workloads and run more efficiently than generators designed to operate solely on unleaded gas.
Disadvantages
Diesel powered generators are typically louder than generators powered by unleaded gas. Large storage tanks and local regulatory requirements can increase the installations costs, hassle, and maintenance of the generator system. Diesel powered generators are heavier and not as portable as most unleaded gas generators.
Finally, diesel engines emit more pollution and some states limit the number of hours per year a diesel engine may be run.
Recommendation
Diesel fuel generators are great for industrial use and in home use situations. They tend to be a little more expensive but are reliable and long lasting. See our Best Diesel Generators For Home review. See Diesel Generators For Sale.
Liquid Propane Gas
Advantag
es
Propane is an outstanding fuel choice for generators. Engines run more quietly on propane, making it excellent for home use. Propane is a cleaner burning fuel than gasoline and is more emission compliant. Propane boasts a longer shelf life than unleaded gasoline and diesel. Propane is readily available during power outages and natural disasters when gasoline is often unable to be pumped.
Disadvantages
Propane begins to derate at 20 degrees F and lower so it may not be the best choice in extreme cold (below zero temperatures). Propane is a more expensive fuel and propane generators can cost more to operate than an unleaded gas or diesel generator.
Recommendation
Propane is an excellent fuel for a more quiet and clean experience. It is readily available at most times and home delivery is even option. A great option for temperatures above 20 degrees F. See our Best Propane Generators For The Home review. See Propane Generators For Sale.
Natural Gas Generator
Advantages
Natural Gas generators can be an excellent solution for the home. Natural gas offers an unlimited fuel supply to homes with natural gas. Natural gas engines run more quietly than unleaded or diesel generators. Natural gas is readily available during a power outage as electricity is not required to pump or feed it to your home.
Disadvantages
Natural gas generators may not be a good option for areas prone to earthquakes. Tremors may cause interruptions in natural gas feed. Natural gas generators are more expensive to run and natural gas is less efficient than unleaded or diesel.
Recommendation
Natural gas is a good fuel source for homes with natural gas feeds. Natural gas can offer an unlimited supply of generator fuel but may not be the best solution for earthquake prone areas. Just be sure to follow safety precautions to minimize risks. See here for our Best Natural Gas Generators For Home review. See Natural Gas Generators For Sale.
Conclusion
Each fuel type has its advantages and disadvantages. Your situation will help determine the best fit for you. Why not consider a dual fuel generator or tri fuel generator to allow you to diversify your fueling capabilities? This ensures that you will always be able to find a fuel source for your generator and to use it in any situation at home or on a trip. In hot weather or cold weather.
