This is a tricky question.For efficient operation of the plant the losses in all raw materials should be as low as possible.For inventory purpose companies have got their own policy guideline circulars where they mention say 0.5 to 5% for different types of raw materials which includes fuel oil.

Dear Amir Feroze,
The losses are dependent on many factors, the conditions of the plant operation. Where stocks are are stored, for example the raw material stock yard is covered or open; the de-dusting system of crushing area. Its the theory of nature that material balance shall be like that In = Out.
The thumb rule for raw materials in stacking yard is the actual moisture content from crushed material on daily basis considering no dust emission, whereas for coal it is important to ascertain the difference in the GCV, Ash and VM of Received Coal and that of Pulverized Coal. The historical data can give the optimistic value of losses.
