What You'll Learn
Fuel type: gasoline, propane, diesel, or natural gas
The fuel consumption of a 7500-watt generator depends on the type of fuel used. Here is an overview of the fuel consumption for different types of fuel:
Gasoline
A 7500-watt generator with a 6.1-gallon gasoline tank capacity at 100% load can run for around 4 hours continuously, consuming 1.5 gallons of gasoline per hour. An inverter 7500-watt generator with a larger 6.9-gallon tank can run for 5.5 hours at full load, consuming slightly less at 1.25 gallons per hour.
Propane
An inverter 7500-watt generator with a 4.6-gallon propane tank will run for approximately 3 hours, consuming 1.53 gallons of propane per hour. A non-inverter 7500-watt generator with a 7-gallon propane tank will run for 4 hours at full load, consuming 1.75 gallons per hour.
Diesel
A non-inverter 7500-watt diesel generator with a 3.5-gallon tank can run for 5 hours at 100% load, consuming 0.7 gallons of diesel per hour. Another common diesel generator with a larger tank capacity may consume up to 1.12 gallons of diesel per hour at full load.
Natural Gas
A 7500-watt generator consumes around 1.6 to 2.0 gallons of natural gas per hour. A non-inverter portable generator with a 4.76-gallon natural gas tank will run for approximately 2.5 hours at full load, consuming 1.9 gallons per hour.
It is important to note that fuel consumption depends on various factors, including the wattage, load, and efficiency of the generator. Running a generator at a higher load can result in increased fuel consumption, and it is recommended to avoid operating the generator consistently at 100% capacity for longevity. Additionally, in extreme cold temperatures, the BTU/hr available from a tank may decrease, affecting fuel consumption.

Fuel efficiency
The fuel efficiency of a 7500 hp engine will depend on various factors, including the type of fuel used, the load, and the engine's efficiency. For example, a 7500-watt generator will consume around 1.2 to 1.5 gallons of gasoline per hour, while the same generator using propane will consume 1.5 to 1.75 gallons per hour. Diesel-powered generators are generally more efficient, with consumption rates ranging from 0.6 to 1.15 gallons per hour.
Brake-Specific Fuel Consumption (BSFC) is a standard measure of fuel efficiency for engines, expressed in pounds of fuel consumed per horsepower produced per hour (lbs/hp/hr). For gasoline engines, the BSFC typically ranges from 0.45 to 0.50, while for diesel engines, it is usually around 0.40. This means that a gasoline engine with a BSFC of 0.50 at peak horsepower will consume 0.50 pounds of fuel for every horsepower produced per hour.
Additionally, the load on the engine also affects fuel efficiency. For example, a 7500-watt generator at 75% load will consume less fuel than the same generator at 100% load. Similarly, inverter generators are generally more efficient than non-inverter generators, as they are designed to optimise fuel usage.
Overall, the fuel efficiency of a 7500 hp engine will depend on a combination of factors, including fuel type, engine type, load, and engine specifications. By understanding these factors and making informed choices, users can optimise fuel efficiency and reduce fuel consumption.

Fuel tank capacity
For example, a non-inverter 7500-watt diesel generator typically has a fuel tank capacity of around 3.5 gallons. At 100% load, this generator can run for approximately 5 hours continuously, consuming around 0.7 gallons of diesel per hour. On the other hand, an inverter 7500-watt generator usually has a larger fuel tank capacity of 6.9 gallons of gasoline. With a full load, it can operate for about 5.5 hours, consuming approximately 1.25 gallons per hour.
The fuel type also impacts the fuel tank capacity and the runtime of the generator. Gasoline, propane, diesel, and natural gas are common fuel options for 7500-watt generators. Gasoline is the most popular choice due to its wide availability, ease of storage, and transport, but it can be expensive. Diesel-powered generators are generally more efficient than those using other fuels, resulting in lower fuel consumption. Propane and natural gas are alternative fuel options, but they may have different tank capacities and consumption rates.
Additionally, the load on the generator affects fuel consumption. A generator operating at a higher load will consume more fuel compared to when it operates at a lower load. Therefore, it is recommended to operate the generator at a moderate load to optimize fuel efficiency and prolong its lifespan.
In summary, the fuel tank capacity of a 7500-watt generator can range from approximately 3.5 to 8 gallons, depending on the generator type and fuel used. By considering factors such as fuel type, load capacity, and runtime, you can make informed decisions about choosing and operating a 7500-watt generator to meet your specific needs.

Generator load
The Westinghouse WGen7500 Portable Generator is a popular 7500-watt generator. It produces 9,500 peak watts and 7,500 rated watts, operating for up to 11 hours on a 6.6-gallon (25-litre) gasoline fuel tank. This generator is designed to keep your home prepared for emergency events. It features a Push-Button Electric Start, which pairs with a wireless remote key fob for convenient ignition.
The generator's fuel consumption will depend on the load. At 50% load, the Westinghouse WGen7500 will consume approximately 2.64 litres of gasoline per hour. This means that for every 24 hours of runtime, you would need around 60 litres of fuel.
It is important to note that running a generator consistently at 100% capacity is not recommended for longevity. While the Westinghouse WGen7500 can handle a 75% load, it will consume more fuel at higher loads.
Additionally, the type of load can also impact fuel efficiency. For example, using a generator for heating is generally not efficient, as generators are typically only 15-20% efficient, meaning you will burn 5 times more fuel compared to burning fuel directly for heat.
To optimize fuel efficiency, consider using an inverter generator. Inverter generators can run at an appropriate rpm for the load, resulting in better fuel economy. For example, a 7000-watt inverter generator may consume only 1.62 litres of fuel per hour, offering significant savings over a conventional generator.

Generator wattage
The Westinghouse WGen7500 Portable Generator is a popular option for those seeking a 7500-watt generator. It produces 9,500 peak watts and 7,500 rated watts, operating for up to 11 hours on a 6.6-gallon (25-litre) gasoline fuel tank. This generator is designed to be easy to use and powerful, making it ideal for emergency events. It features a push-button electric start and a wireless remote key fob for convenient ignition.
The Westinghouse WGen7500 is equipped with a 420cc 4-Stroke OHV Westinghouse Engine, ensuring durability and performance. It includes a built-in fuel gauge, automatic low oil shutdown, and GFCI household outlets for added safety and convenience. The generator operates with a low noise level of as little as 72 dBA, making it a quiet option for a 7500-watt generator.
In terms of fuel consumption, the Westinghouse WGen7500 is rated for 11 hours of operation at a 50% load on 29 litres of fuel. This equates to approximately 2.64 litres per hour. However, it's important to note that fuel consumption may vary depending on the load and other factors.
When considering fuel efficiency, it's worth mentioning that generators are typically only 15-20% efficient in converting fuel to electricity. This means that using a generator for heating may not be the most cost-effective option, especially in regions with high fuel costs.
Additionally, some users have suggested that running a generator at a lower load may result in increased fuel consumption per watt consumed. This is because an engine typically operates most efficiently at its full rated load. Therefore, it is recommended to operate a generator close to its rated load while allowing some cushion for excess loads.
In summary, the Westinghouse WGen7500 Portable Generator is a powerful and convenient option for those seeking a 7500-watt generator. With its durable engine, long runtime, and safety features, it is well-suited for emergency situations. However, as with all generators, fuel consumption and efficiency are important considerations, and alternative heating methods may be more cost-effective in certain circumstances.
