Generator fuel consumption has always been a concern of many in deciding on what generator to buy. Diesel-powered generators tend to be more fuel-efficient than petrol ones, with a 120kW diesel generator achieving an efficiency of between 10.9 and 32.1 litres per hour depending on its load, which is considerably better than a petrol generator. Here, we provided you with an approximate diesel fuel consumption of diesel generators from 10KVA to 500KVA units. Note that; there may be a slight difference in actual fuel usage due to various factors. The table below may only be a close reference if not exact to get a better idea of diesel generator fuel consumption.
