There are not any calories in diesel fuel oil. Diesel fuel oil should not be consumed by humans or animals. Consumption of the fuel oil can be fatal.
Diesel fuel is often referred to as "diesel oil" or "heavy oil". Do not confuse this with "engine oil for a diesel engine" which means "lubricating oil specially formulated for use in diesel engines". My first Ford Fiesta diesel's tax disc said - "Fuel - Heavy Oil". They've now realised that this term is anachronistic, and my latest tax disc reads "Fuel - Diesel". To be pedantic - Diesel fuel is an oil - Petrol is a spirit.
