How much fuel in gallons per hour does one 60 kilowatt mobile electric power generator use?

Fuel use for a generator scales with the power it must deliver and the engine’s efficiency. A 60 kW diesel mobile generator, when running at its full rated output, typically consumes about five gallons of fuel per hour. To see why, convert power to horsepower (60 kW ≈ 80 hp). Diesel engines often have a brake specific fuel consumption around 0.45–0.50 lb of fuel per horsepower per hour. Multiplying 80 hp by about 0.48 lb/hp-hr gives roughly 38 lb of fuel per hour. With diesel density around 6.8–7.0 lb per gallon, that’s about 5–6 gallons per hour. In practice, manufacturers cite roughly five gallons per hour at full load for a generator of this size, so five is the best choice. Lower load uses less fuel, while the other options imply either unrealistically high or low consumption for a 60 kW unit.
