A generator’s fuel consumption varies depending on its size, load, and efficiency. On average, a gasoline generator consumes about 0.5 to 1 gallon per hour of operation per 10 kilowatts of power output. In metric terms, this equates to approximately 2 to 4 liters per hour per 10 kW of power delivered. Actual consumption may vary depending on specific generator model and operating conditions.
The amount of fuel used by a generator is usually measured in gallons or liters per hour.
Small portable generators can use about 0.2 to 0.5 gallons per hour (0.8 to 2 liters per hour) at a moderate load, while larger generators can use more fuel. For accurate fuel consumption, it is essential to refer to the generator’s specifications and consider the load it is handling.
The cost of running a generator all day depends on its fuel consumption and local fuel prices. For a generator that consumes 1 gallon per hour and whose gasoline costs $3 per gallon, running the generator for 24 hours would cost approximately $72.
This calculation assumes continuous operation at the given consumption rate and fuel price. Costs vary based on actual fuel consumption and local fuel rates.
A gasoline generator typically runs for 8 to 12 hours on a full tank, depending on its tank size, load, and efficiency. Smaller generators with smaller tanks can run for shorter periods of time, while larger generators with larger tanks can run for longer durations before needing a recharge. Exact run time may vary depending on generator electrical load and operating conditions.
