Oil energy saving

jen_jen_2

This may seem like a silly question, but do you save the amount of oil used in the same way you would save gas and electricity or can you not be more efficient because the oil burns at the same rate when you need to power the burner for hot water and heating?

What i mean is if I turn off some radiators but have others on does it consume the same amount of oil as having them all on? They are not thermostated so either hot or cold.

Any tips on how to consume less fuel would be greatly received
