Whether you need one for your home during emergencies or for outdoor activities and remote job sites,  picking the right fuel can make a big difference in how long your generator works, how much it costs, and its impact on the environment.

Knowing your fuel options helps you make smarter choices, making sure you have a practical and reliable power source whenever you need it.

 

Understanding Fuel Types: Propane vs. Gasoline

In terms of keeping your indoor generators running effectively, you’ll come across two common fuel choices: Propane and gas, each offering its own perks and drawbacks. Let’s break down a bit.

Propane

Propane is one of the popular fuel choices for standby and portable power stations. It’s an awesome source as it burns cleaner, which means less pollution and fewer deposits gunking up your generator. It has got a longer shelf life, making it an excellent choice for emergency preparedness, so you don't need to worry about it going bad. Plus, it performs well even in cold weather. So, if you’re after a greener option with low maintenance, propane is a good-to-go fuel choice.

Gas

When talking about gasoline, it’s all about power and convenience. It has a higher energy density, which means you get more energy out of each gallon. Also, You can find gasoline just about everywhere, which makes it super handy and practical. It’s perfect for those times when you need to refuel quickly and want to keep things moving.

Coming to both fuel options, each holds its significance for different reasons. Gasoline is found to be the common fuel choice used in portable generators. On the other hand, propane is most favored for standby generators since it typically runs quieter, stores well, and demands less maintenance over time.

 

Energy Content and Efficiency

When breaking it down to evaluating the energy content and efficiency of propane versus gas, it’s good to know how each fuel impacts the performance of your home generator.

Energy content is measured in British Thermal Units or jouls, which translates to the amount of power each fuel can produce and how long it can run on it.

Gasoline is a heavy hitter here. A gallon of gasoline has about 114,000 BTUs, which means it packs a lot of energy. Due to this, gasoline-powered generators can run longer on full tanks compared to their propane counterparts. Ideally, if you’re looking for a generator that can keep going for as long as possible without frequent refueling, gasoline is a solid choice.

Propane, on the other hand, has around 91.500 BTUs per gallon, so visibly it doesn’t have as much energy as gasoline. Apparently, a propane generator will need more fuel to produce the same amount of power equivalent to gasoline and it won’t run longer as a single tank.

But mind it, propane has its own perks. It burns cleaner so there’s less carbon buildup and very few emissions. This would make your generator’s engine perform longer with reduced maintenance.

Ultimately, if you need a lot of power and want your generator to run for extended periods, gasoline might be the way to go. But if you’re looking for a cleaner, more environmentally friendly option that’s easier on your generator over time, propane is a great alternative.

 

Calculating Run Time

Several factors influence the run time of a generator, including the fuel type, tank capacity, and load. Understanding these factors helps you manage your generator usage and consequently, you can optimize its run time effectively.

All you need to do is divide the tank capacity and fuel energy content by the consumption rate. This will make it possible to estimate the generator’s runtime. Here’s a simple formula:

Run Time=  Tank Capacity×Fuel Energy Content​                     —---------------------------------------------                               Load in watts

Where:

• Tank Capacityis the amount of fuel your generator can hold, in gallons.
• Fuel Energy Contentis the energy provided by the fuel, in BTUs per gallon. For gasoline, it's approximately 114,000 BTUs per gallon. For propane, it's about 91,500 BTUs per gallon.
• Loadis the power demand on the generator, in watts.

Example Calculations:

Let’s suppose you’ve got an average-sized generator with a tank capacity of 5 gallons and a constant load of 2000 watts.

For Gasoline,

1. Tank Capacity: 5 gallons
2. Fuel Energy Content: 114,000 BTUs per gallon
3. Load: 2,000 watts

Using the formula

Run Time=  5 gallon  × 114,000​ BTUs / gallon                     —------------------------------------------                                    2000 watts

Run Time=   570,000 BTUs                     —-------------------                         2000 watts

Converting BTU to watts= 1 BTU = 0.29307107 watts):

Run time (Gasoline) =   570,000 X  0.29307107                                         —------------------------------                                                   2000 watts

Run time (Gasoline) =  83.5 hours

For Propane

1. Tank Capacity: 5 gallons
2. Fuel Energy Content: 91,500 BTUs per gallon
3. Load: 2,000 watts

Using the formula:

Run Time=   5 gallon  × 91,500​ BTUs / gallon                      —------------------------------------------                                     2000 watts

Run Time (Propane) =   457, 000                                        —------------                                        2000 watts

  

Converting BTUs to watts (1 BTU = 0.29307107 watts):

Run Time (Propane) =   457, 000 X 0.2307107                                         —----------------------------                                                  2000 watts

Run Time (Propane) =   67.1 hours

In evaluations, we observed that gasoline-powered generators would run for approximately 83.5 hours whereas using propane, it recorded a run time of 67.1 hours, given the same load and tank capacity. These calculations illustrated the run time using the varying energy content of the fuels.  For a definite answer, you may consider this run time and other benefits each fuel offers to arrive at the best options for your needs.

 

Fuel Tank Capacity and Its Impact on Run Time

Apart from the energy content being a significant factor influencing the generator's longevity, the size of the fuel tank also determines how long the generator can run before needing a refill.

A typical fuel tank size of a portable power station generally ranges from around 1 gallon to 10 gallons, depending on the model and what you need it for. Small-sized generators, suitable for camping or small-duty tasks might have tanks on the lower end of this range, while bigger, more powerful units meant for heavy-duty usage or home backup have larger ones.

For example

Small Generators (1-2 Gallons): They’re used for everyday camping or charging small appliances and tools. They offer shorter run times but are lightweight and easy to carry.

Medium-Sized Generators (3-6 Gallons): They’re good options to power common household appliances during outages of several hours.

Large Generators (7-10 Gallons):  They’re meant for extended power needs such as Whole-house backup or continuous operation on job sits.

Here, it’s important to note that not only the tank size of a generator dictates its run time but also the load being powered on it. Indeed a larger fuel tank means longer run times between refueling, but you need to consider the energy efficiency and the devices connected to it.  

 

Storage and Availability

In regards to analyzing the storage and availability of both fuel options, let us tell you that each offers its own set of benefits and challenges. Comprehending them in detail may help you make more informed choices during emergency preparedness and everyday needs. So let’s get into the details.

Propane

Propane is one of the finest fuel choices for portable generators today and it’s easy to see why. Many regard it to be the most reliable fuel with an indefinite shelf life, impressive power output, and eco-friendly profile.  

Unlike gasoline, which can degrade over time, propane stays effective no matter how long you keep it. From small 20-pound cylinders commonly used for a grill to a larger 100-pound tank for extended use, there’s an option that fits your needs.

Plus, propane tanks are safer and more robust with built-in features to prevent leaks and pose a minimum risk of fire or explosion.

It’s also worth mentioning that propane is a safer option compared to natural gas, as it doesn’t require a dedicated pipeline connection.

So, overall it’s pretty an excellent option for keeping a reliable fuel supply on hand, especially during emergencies. You can rest easy knowing that your fuel won’t go bad and that your generator will be ready to go whenever you need it.

When it comes to availability, propane may not be as readily available as gasoline, and the initial setup, including purchasing tanks and connectors, can be more expensive.

Nowadays, many retailers offer propane tank exchange programs, so you can easily swap an empty tank for a full one. This is a convenient option for maintaining a continuous supply without the hassle of refilling tanks yourself.

Gasoline

Gas fuel for generators is a pretty efficient alternative in regards to squeezing out power from each gallon of fuel. Gas-powered generators are widely available with a wide range of portable options, perfect for camping trips and outdoor adventures where you need reliable power on the go.

One of the big pluses of gas fuel is its widespread availability at numerous gas stations and convenience stores across urban and rural areas. This extensive distribution network ensures that you can usually find gasoline nearby for refueling your generator.

Also, this fuel option is highly affordable, so you’ll find it quite cheaper than other types. But here’s the catch: gasoline prices can shoot up during emergencies when everyone’s rushing to fill their tanks, so that’s something to keep in mind.

Another thing with gasoline is that it doesn’t last forever. You’ve got to store it carefully and use it up before it goes bad, which usually happens within a few months unless you treat it with stabilizers. Managing your fuel supply becomes crucial, especially if you’re stocking up for emergencies or planning for long-term storage.

 

Environmental and Cost Considerations

As a user of portable power stations, one must know the environmental and cost considerations for both fuel choices. Here's a breakdown of how these two fuel types compare:

Environmental Impact

Propane: Compared to gasoline, propane burns cleaner with less buildup of soot and carbon in the engine. Consequently, it leads to a longer lifespan for your generator and fewer maintenance headaches.

Gasoline: The combustion of gas leads to the release of harmful emissions, contributing to air pollution and environmental damage. Even though newer engine technology has cut down on some of these emissions, gasoline still has a bigger environmental impact compared to propane.

Cost Implications:

Fuel Costs:

Propane: Propane prices can vary but are generally pretty stable. While it might be a bit pricier per gallon than gasoline, its efficiency and cleaner burn help balance out some of those costs. Plus, propane has a longer shelf life, so you deal with less waste and fewer problems with fuel going bad.

Gas: Gasoline is usually cheaper per gallon upfront, making it a cost-effective choice initially. But gas prices can swing wildly, especially during emergencies or high demand periods, which can make your overall fuel costs less predictable.

Maintenance Costs

Propane: Propane-powered generators are low-maintenance champs because propane burns so cleanly. There's less carbon buildup and fewer deposits in the engine, meaning you can go longer between maintenance sessions and potentially get more years out of your generator.

Gas: Gasoline engines need more frequent maintenance because of the carbon buildup and other residues from burning gas. Over time, this means higher maintenance costs and possibly a shorter lifespan for your generator.
