 # How Much Gas Does A 7500 Watt Generator Use?

A 7500-watt generator consumes around 1.20 to 1.5 gallons of gasoline per hour. If you run the generator with propane, the consumption will be 1.50 to 1.75 gallons per hour. And it will consume around 0.6 to 1.15 gallons of fuel if the generator runs on diesel. If you use natural gas in the 7500-watt generator, you will need 1.6 to 2.0 gallons of them per hour.

Keep reading to know how much gas does a 7500 watt generator use and what external factors you have to consider to determine this fuel consumption.

## How Much Gas Does A 7500 Watt Generator Use?

Here is the gas consumption of a 7500-watt generator for different fuel types.

### How Much Gasoline Does A 7500 Watt Generator Use?

A 7500-watt generator generally uses around 1.20 to 1.5 gallons of gasoline per hour depending on the generator type.

A non-inverter portable generator has a gasoline tank capacity of 6.1 gallons. At 100% load, it can run for around 4 hours continuously. So, the gasoline consumption of this generator is (6.1 / 4) = 1.5 gallons of gasoline per hour.

On the other hand, an inverter 7500-watt generator has a 6.9-gallon gasoline tank. With 5.5 hours of the full load back, it consumes (6.9 / 5.5 ) = 1.25 gallons per hour. So, an inverter generator consumes slightly less gas per hour.

Using this formula, you can also determine the fuel consumption of a 3000 Watt generator

### How Much Propane Does A 7500 Watt Generator Use?

A 7500-watt generator uses around 1.50 to 1.75 gallons of propane per hour.

For example, an inverter 7500-watt generator has around 3 hours of run time. And the fuel capacity of this is 4.6 gallons of propane. So, it will consume (4.6 / 3) = 1.53 gallons of propane.

Another non-inverter 7500-watt generator requires a 7-gallon propane tank. The runtime of this generator at full load is 4 hours. So, the propane consumption by this 7500-watt generator is 1.75 gallons per hour.

### How Much Diesel Does A 7500 Watt Generator Use?

A diesel-powered generator uses around 0.6 to 1.15 gallons of diesel per hour depending on the generator’s efficiency. Diesel-powered generators are usually more efficient than generators powered by other fuels.

For example, a non-inverter 7500-watt diesel generator has a fuel tank of 3.5 Gallons. And at 100% load, the generator runs for around 5 hours continuously. So, you will need around (3.5 / 5) = 0.7 gallons of diesel per hour.

Another common diesel generator takes up around 1.12 gallons of diesel per hour at full load.

### How Much Natural Gas Does A 7500 Watt Generator Use?

A 7500-watt generator uses around 1.6 to 2.0 gallons of natural gas per hour.

For example, A non-inverter portable generator has a natural gas tank of 20 pounds or 4.76 gallons. At full load, it runs for around 2.5 hours continuously. So, the natural gas consumption of this generator is (4.76 / 2.5) = 1.9 gallons per hour.

## What Does The Fuel Consumption Depend On?

Obviously, the generator wattage is the main factor on which the fuel consumption depends on. A 2000-watt generator’s fuel consumption is lower than a 7500-watt one.

However, fuel consumption depends on many things other than just the wattage. Here are those factors.

### Fuel Type:

Depending on the fuel type, the generator consumption varies. For example, gasoline is more efficient than propane. And if you use diesel, your generator will consume less than gasoline.

### Generator Type:

Inverter generators are more efficient than non-inverter generators. As a result, inverter generators of 7500 watts will consume less fuel than a non-inverter 7500-watt generator. Also, stand-by generators are more efficient than portable generators.

### Generator Efficiency and Age:

Depending on the generator’s quality and brand, it can consume more or less fuel. High-quality generators are more efficient. Also, with time, generators keep losing efficiency and consume more fuel.

Usually, we don’t run generators at 100% load. But if you run a generator on full load, it will consume more fuel than at 50% or 25% load.

Considering these factors, you can also determine the fuel consumption of other generators, like 6500-watt generator fuel consumption

### Will A 7500-Watt Generator Run My Air Conditioner?

A 7500-watt generator can run your generator if the generator is 1 ton or 1.5 tons. If the AC is 2 tons, a 7500-watt generator can not run it. For every ton, you need at least 3500 watts of surge power. And keeping the generator efficiency in mind, having a slightly larger generator is recommended.

### Will A 7500 Watt Generator Run A Furnace?

No, a 7500-watt generator can not run a furnace. Depending on the size, a furnace takes around 10,000 to 50,000 watts. So, it is impossible for a small generator like 7500 watts to cover the power.

### How Much Does A 7500 Watt Generator Cost?

A 7500-watt generator will cost you anywhere between \$700 to \$2000. The price depends on the generator type, brand, and efficiency. Inverter and stand-by generators cost more than non-inverter and portable generators.

## Conclusion

There goes our discussion on how much gas does a 7500-watt generator use. Now you can predict the fuel usage of your generator earlier and be prepared according to that.

Also, try to perform regular maintenance of your generator for better fuel efficiency.

That’s time for me to say goodbye. Have a nice day!
