Bernerd Fulanda answered on 5 Jul 2017:
It is so because we know oil is lighter than water, so any unburnt oil forms a light layer over water and as the water covers large area, when you add more and more water you are simply spreading the fire because the oil continues to burn ontop of the water and as the water flows, so does the fire

water is made up of hydrogen and oxygen atoms. as you are a ware oxygen supports combustion. in an oil fire, the heat produced is adequate to ionize the water molecules into oxygen and hydrogen, the oxygen will support burning

You say water cant be used to extinguish oil fire, what should we use then?
Joseph commented on :
you fire extinguishers which are usually a mixture of chemicals which do not support burning and water for example carbondioxide is agood example of a gas that does not support burning.
