What type of fuel do you need for a generator?
Generators can run on different types of fuel, depending on the model and design. The most commonly used fuels for generators are gasoline, diesel, natural gas and propane. Gasoline is often used for portable generators because it is widely available and convenient for short-term use.
Diesel is preferred for larger, more powerful generators, especially in commercial or industrial settings, because it is more energy dense and more efficient for continuous operation.
Natural gas and propane are cleaner alternatives, often used for backup generators connected to a home’s natural gas line or with large propane tanks for extended use.
What fuel should I put in a generator?
Choosing fuel for a generator depends on several factors, including availability, cost, and intended use of the generator.
Gasoline is commonly used for portable generators due to its availability, but it is not ideal for long-term storage. Diesel fuel is preferred for heavy-duty generators because it provides more power per gallon and is more efficient for extended use. Natural gas is often used for backup generators because it provides a continuous supply of fuel when connected to a utility line.
Propane is another option, popular for its clean-burning properties and long shelf life, making it suitable for portable and standby generators.
What fuel for the generator?
For gasoline generators, regular unleaded gasoline with an octane rating of 87 or higher is generally recommended. Some generators may also be compatible with gasoline containing up to 10% ethanol (E10). However, blends with high ethanol content, such as E15 or E85, should generally be avoided because they can damage the engine and generator fuel system.
It is important to use fresh gasoline and, if you are storing gasoline for future use, to add a fuel stabilizer to prevent the fuel from breaking down and causing generator performance problems.
The amount of fuel a generator uses depends on its size, load, and fuel type.
On average, a small portable gasoline generator can consume about 0.5 to 1 gallon of fuel per hour when operating at half load. Larger diesel generators can consume between 1.5 and 3 gallons per hour, depending on the load. Propane and natural gas consumption also varies, with propane generators typically using about 0.5 to 2 gallons per hour and natural gas generators using about 100 to 250 cubic feet per hour.
Energy efficiency can also be affected by the age, maintenance and general condition of the generator.
Generators are powered by several types of energy sources, depending on the model and intended use. The most common fuels are gasoline, diesel, natural gas and propane. Some generators are dual-fuel or tri-fuel, meaning they can run on more than one type of fuel, providing flexibility depending on fuel availability. In some cases, generators can also run on biofuels or even solar power, although this is less common.
Fuel choice impacts generator runtime, efficiency and environmental footprint, making it an important factor when selecting a generator for specific needs.
