# How do you calculate fuel consumption of a gas generator?

**fuel consumption**model will look something like this: Gallons

**consumed**per hour = k + p*X where “k” is the gallons per hour of

**gasoline consumed**with no power load and “p” is the rate at which

**gasoline**is

**consumed**to generate X watts of power. The “k” factor is similar to idling your car at a stop light.

Also, how much fuel does a generator use per hour?

Gasoline is the most common **fuel** source for portable **generators**. A standard 5-kilowatt **generator** will typically consume about 0.75 gallons **per hour**.

Subsequently, question is, how much gas does a 2000 watt generator use? Barely an hour and a half for a standard **2000 watt generator**, which consumes around three-quarters of a gallon of **gas** hourly.

Moreover, how much gas does a 4000 watt generator use?

**Gas generator** consumes an average of . 5 gallons of **fuel** per hour at half load.

How much gas does a 3500 watt generator use?

The **3500**-**watt generator** is **fuel** efficient. In fact, you can keep an inverter **generator** running for 8 or 10 hours **using** only 2 to 3 gallons of **gas**. In addition, most **generators** with a **3500**-**watt** capacity are affordable and are widely available.
