Diesel Fuel Consumption Chart (Approximate)
This chart provides an approximation of the fuel consumption of a diesel generator based on it’s size and the load. Please note that this table is meant to be used as an estimate of how much fuel a generator consumes during operation and is not an exact representation due to a variety of factors that can increase or decrease the amount of fuel consumed.
