How Much Gas Does A Gas Generator Use Per Hour And Day? I had no idea how much gas a generator would use before buying one. A lot of people are curious to see what the specs on their generators are and to find out what features they might need. When you’re first looking at your options, it can be overwhelming to compare them all. With all the information available, you may end up looking for generators in different categories that aren’t suited for each other because they have different usage needs. But there is help on the way! This article will show you how much gas a generator uses, so that you can be sure to buy a generator with enough fuel capacity and electricity output for your job site needs. Before going to the main point, let us tell some basic things about gas consumptions.

Why Gas Consumption Rates of  Gas Generator Varies?

  1. Generator Type

A manual stick generator has different consumption rates than an electric one. The latter uses way less gas, because it is not as dependent on the power source. However, it runs faster and consumes more fuel, so you would have to have a bigger fuel tank.

  • Standby
    A standby generator uses way less fuel than a portable one, because it only works when it is needed. This means that the engine doesn’t run continuously, and thus has a lower gas consumption rate.
  • Portable
    Portable generators consume more fuel than a standby one, because they are constantly running. The engine is constantly burning fuel, and speed up the more it goes. Now let’s get to the main topic: gas consumption!
  • Inverter
    Most people have an inverter, which is a device that converts DC electricity to AC and vice versa. Simply put, it’s a power converter
  • Portable Generator
    A portable generator is light weight and doesn’t need to have a lot of fuel capacity, which means that its gas consumption rate will be lower than that of a standby generator. But it can consume more fuel when you use it at maximum capacity or when you over utilize the power source. This means that the amount of gas used depends on how much you use it and what you run on it.
  • Duel Fuel Generator
    It’s a generator that can be run on natural gas, propane, or liquid fuel. So it’s not only dependent on electricity and its consumption rate varies depending on the fuel you use for running it.
  • Tri-Fuel
    It has three different fuel types – gasoline, diesel, and residual oil. This means it consumes more fuel than a portable generator that runs on one fuel only. It also has a higher consumption rate than a standby generator. If you use it at maximum capacity or over utilize the power source (like running a lot of tools at the same time), it will consume more gas.
         2. Type of Work

A generator may consume more gas when running for construction work vs. a farm or industrial site. It all depends on the type of job you’ll be doing: If you need a lot of power to run equipment or work on large projects in your yard, then you have to pick a bigger generator that consumes less gas, but gives more power output!

         3. Type of Work

A battery is capable of supplying power to a device while you are walking, running or doing other activities. But this requires additional gas consumption. This means that if you have a larger battery and less load, then the generator won’t be as efficient as it will consume more gas than if it had a smaller battery but more load.

The type of work a possible generator will be used for may also influence its gas consumption rate. Inverter generators use less fuel than stand-by generators when you’re just sitting around – they use it when the ambient temperature is low and electricity rates are high. Stand-by generators use little to no fuel when your electricity rate is low and the weather is hot!

How Much Gas Does a Generator Use?

Before buying a generator, you should know the minimum amount of gas it will consume. It is very easy to calculate this using the following simple formula:

Gas Consumption (in L/h) = Power (in W) x Time (in h).

Assuming that you are using a standard generator which consumes 5.2 L per hour and has an output power of 5000 W, then your gas consumption will be 5000 x 5.2 = 26000 L over the course of one hour!

How Much Gas Does A Generator Use Per Hour?

Gregory’s Law states that the power in a generator is equal to the motor power and the voltage. Since most generators have a voltage of 220 V, this means that the internal combustion engine would produce an output of 220 x 5 = 1,200 W. The total power of the generator is then: 1,200 W + 5.2 L/h = 1,214 W total per hour.

How Much Gas Does A Generator Use Per Day?

To determine how many hours you can run before you run out of gas, you can set up a spreadsheet with the values for your generator (or batteries) and compare it to what your total electricity usage is over that period of time. Then, calculate the difference from your actual usage and divide by the number of hours to determine how many gallons you need.

So for example, let’s say that you are running a 500 W generator for one hour out of each day for 20 days at a rate of 2.42 kWh per day (which equals 784 kWh total over the course of your work week). From your spreadsheet, you should have 1.2 kWh in electricity use each day (7840 kWh/21 days), and so your calculated daily gas consumption can be determined quickly by using this formula:

GPM = 0.8 x grid power in kWh (7840 joules)

GPM = 0.8 x (0.82 kWh/hour)

GPM = 784 / 0.0083

= 1342 gallons used per day!


Generators are very useful devices when there is a power outage – you can use them as generators for most of your appliances, such as your refrigerator and TV. Yes, they do consume a lot of fuel but it’s still better than being without power! If you want to have the peace of mind that comes with knowing that you can stand a long blackout with ease, then generators will help you achieve this goal. The most important factor to consider is what type of generator you’re going to buy. It should be reliable and it should give the power output that matches the load requirements and type of work that will be done on it based on its capacity.
