You can calculate fuel consumption per Kilowatt hour in diesel engine by multiplying the miles per gallon by the wattage per hour that the engine runs. This gives the net Kilowatt hour fuel consumption.

The consumption of lubricating oil for a diesel engine depends on the operating conditions and the design of the engine. There are some averages depending on the year of the engine. Pre 1980's engine are around 25% of fuel consumption. Pre 1990 engines are around 20% of fuel consumption and more recently built diesel engines are around 1% of fuel consumption.
Diesel Engine SFC is Specific Fuel Consumption of Diesel Engine. This used to know how efficient Fuel utilization of Diesel Engine to produce electricity. Usually formula of SFC is Fuel Consumption divided by Electricity Production (liter/kWh).

There are several causes for high fuel consumption in a diesel engine. These include a difference in the weight of the vehicle, increased usage of air conditioning, and a difference in tire pressure.
You will need to have some information ready. It is good to know the horsepower and the torque of your diesel engine.
IT CAN BE CALCULATED THEORETICALLY & PRACTICALLY:- 1. theoretically--- For this you must know the SFC(specific fuel consumption) of the engine at the given load. for example(let us consider a diesel generator of 20 kw having SFC as 232 gm/kw-hr at 75% load) (20x0.75)x232 therefore Fuel consumption in ltrs/hr= =4.094ltr/hr 0.85x1000 here 0.75 is for 75% load 0.85 is density of diesel 1000 is factor to convert milli-litre into litres
Depends entirely on the load being applied to the engine.

The primary difference between a petrol car and diesel car is the consumption rate - diesel and petrol are refined from mineral oil using differing methods. The result is diesel engines having a lower fuel consumption rate than their petrol counterparts when installed in a vehicle of similar mass. CO2 emissions are also lower in a diesel engine than they are in a petrol engine.
As a rough rule of thumb, you can assume you will burn one third of a liter of fuel per kilowatt-hour generated. With a reasonable degree of instrumentation on a battery of 600kw diesel generators, we measured fuel flow vs power generated, and got a factor of .287 liters per kilowatt hour. These were relatively new generators powering a fairly level load. If the engines are smaller, if the load fluctuates, if the engines have high operating hours, the factor will increase.
