Gasoline is the most common fuel source for portable generators. It is readily available at most gas stations and is relatively affordable. However, gasoline has a shorter shelf life compared to other fuel sources, so it may not be ideal for long-term use or in areas where fuel availability may be limited during emergencies. It is important to store gasoline safely and in approved containers to prevent spills and fire hazards.


Diesel fuel is known for its efficiency and longevity. Diesel generators are generally more fuel-efficient and have a longer run time compared to gasoline generators. Diesel fuel is also less flammable than gasoline, making it a safer option in some environments. However, diesel fuel can be more expensive and may require additional maintenance compared to gasoline generators.


Propane is a clean-burning fuel that is often used in standby generators. It is easily stored in tanks and can be refilled as needed. Propane generators are quieter than gasoline or diesel generators and produce fewer emissions. However, propane can be more expensive than gasoline or diesel, and the availability of propane may be limited in some areas.

Environment and Location

The environment and location where you plan to use your generator play a crucial role in determining the type and size of generator you need.


Using a generator indoors can be extremely dangerous due to the risk of carbon monoxide poisoning. Generators emit carbon monoxide, a colorless and odorless gas that can be deadly if inhaled in high concentrations. If you need to use a generator indoors, ensure that it is properly ventilated to prevent the build-up of carbon monoxide. It is highly recommended to use a generator outside, in a well-ventilated area to ensure the safety of yourself and others.


Using a generator outdoors is generally safer than using it indoors. However, it is still important to consider factors such as weather conditions and accessibility. Generators should be placed in a level, dry area away from flammable materials and should be protected from rain or snow. It is also important to consider noise levels, as generators can be quite loud and disturb your neighbors or surrounding environment.


Proper ventilation is essential when using a generator. Whether you are using it indoors or outdoors, ensure that there is enough fresh air circulation to prevent the build-up of carbon monoxide. If using your generator in an enclosed space, such as a garage, it is important to provide proper ventilation by opening doors or windows. Additionally, consider using carbon monoxide detectors to alert you of any dangerous gas levels.

Run Time

The run time of a generator refers to the duration for which the generator can operate on a single tank of fuel. It is an important factor to consider depending on your power needs and the length of time you anticipate needing backup power.

Short-Term Use

If you only require backup power for short periods, such as during a temporary power outage, a generator with a shorter run time may suffice. Portable generators, particularly those powered by gasoline, often have relatively shorter run times. However, it is important to have enough fuel on hand or a reliable supply of fuel to ensure uninterrupted power when needed.

Long-Term Use

If you anticipate needing backup power for longer durations, such as during long power outages or in remote locations without access to electricity, a generator with a longer run time is crucial. Standby generators, particularly those running on propane or diesel, typically have longer run times and can provide continuous power for days or even weeks with proper maintenance and refueling.

Maintenance Requirements

To keep your generator in optimal condition and ensure its reliable performance, regular maintenance is essential. Here are some common maintenance requirements you should consider.

Fuel Refilling

Regularly refilling your generator with the appropriate fuel is crucial to ensure uninterrupted power supply. Depending on the fuel source, you may need to store and handle fuel safely and refill the generator’s tank periodically.

Oil Changes

Just like a car, a generator also requires regular oil changes to keep its engine running smoothly. Consult the manufacturer’s guidelines to determine the recommended oil change intervals and ensure you use the correct type and grade of oil.

Filter Replacements

Air filters and fuel filters play a vital role in the proper functioning of your generator. Over time, these filters can become clogged with dirt and debris, affecting the generator’s performance. Regularly inspect and clean or replace these filters as recommended by the manufacturer.

Regular Inspections

Performing regular inspections of your generator is important to identify any potential issues before they worsen. Check for loose or damaged parts, leaks, and any signs of wear and tear. Additionally, ensure that all electrical connections are secure and in good condition.

Safety Considerations

Safety should be a top priority when operating a generator. Here are some key safety considerations you should keep in mind.
