Diesel Generator Fuel Consumption per Hour

An important piece of information you need to have when buying or renting any kind of generator — in Malaysia or anywhere — is its fuel consumption.

The last thing you will want to do in the event of a power cut is refilling the generator with fuel every hour because you ended up installing a not-so-efficient backup generator.

Nonetheless, the fuel consumption of a generator can be dependent on several factors. A genset that uses more power will understandably drink up more fuel.

When looking at the fuel consumption per hour of a 100 kVa generator, for example, it’s not only vital to consider the size of the generator. You will also need to factor in the length of time it is being used, the appliances or tools attached to it, and the type of fuel.

Interested in knowing the diesel consumption of a 30 kVa generator or even a Cummins 500kVa diesel generator for your business in Damansara or Kepong?

Call us at Power Pro today. Power Pro can help determine the approximate fuel consumption of your desired generator according to size.
