## How much fuel does a 5kw generator use?

With a five-kilowatt generator consuming 0.75 gallons per hour, you’ll consume up to 18 gallons of gas per day.

**How many Litres does a generator consume per hour?**

Diesel Generator Fuel Consumption Chart in Litres

Generator Size | Approximate Diesel Fuel Consumption | |
---|---|---|

¼ Load (litres/hr) | Full Load (litres/hr) | |

8kW / 10kVA | 0.8 | 2.4 |

10kW / 12kVA | .9 | 2.9 |

12kW / 15kVA | 1.1 | 3.6 |

### How much fuel does a generator use per day?

Most portable generators will run on gasoline out of convenience. A standard 5,000 watt generator will consume around 18 gallons of gasoline during a 1 day/24 hour period.

**How long can I continuously run my generator?**

Depending on your standby generator, most manufacturers recommend that you limit your generator to 500 hours of use at the most. That’s about three weeks of continuous use.

## How much fuel does an 82.5 kVA generator use?

To get optimal performance of 82.5 kVA generator the suggested load excess is 25%. Also, the radiator & fan of the engine affects the diesel consumption of a DG Set. The fuel consumption rate is mainly dependent upon the 82.5 kVA generator load capacity.

**What is the fuel consumption of a diesel generator?**

This chart approximates the fuel consumption of a diesel generator based on the size of the generator and the load at which the generator is operating at.

### How many litres of diesel does a 25 kVA use?

At 20 kW load (full noise for your 25 kVA genset if it is rated at 0.8 pf) that will be about 5.4 litres per hour. This calculation isn’t perfect, it will be too low at very light loads and also be too high for modern diesels over 500 kW. But close enough if you just need to know when to fill the tank.

**What is the fuel consumption of a DG set?**

The diesel consumption rate for any DG Set mainly depends on its load capacity. That means when you operate a DG Set in various load capacity the fuel consumption rate is different. To get optimal performance of 82.5 kVA generator the suggested load excess is 25%. Also, the radiator & fan of the engine affects the diesel consumption of a DG Set.

## Which is more fuel efficient 10kW or 100kW generator?

For that reason, a 100kW generator will burn more fuel at 10kW than a 10kW generator set. Can I believe the manufacturer’s spec sheets when it comes to fuel consumption?

**Why do some generators burn more fuel than others?**

Chart numbers represent estimated gallons per hour consumed (Gallons/Hour, Gal/Hour). Why do some engines burn more fuel than others at the same load? The biggest factor is fuel consumption related to cooling fans and water pumps of various generator sets. For that reason, a 100kW generator will burn more fuel at 10kW than a 10kW generator set.
