Could overheating an engine make the engine use more/excessive engine oil (motor oil)?
BTW, my engine spec VW Lupo 1.4 litre 16V (petrol) and does the coolant temperature sensor controls the radiator fan on this particular model because I haven't noticed the fan being switched on in a while?

Yes, if the coolant gage on your dash is either reading a high temperature or none at all check the coolant level in the radiator and the coolant recovery container.
The sensor must be immersed in antifreeze / water to enable it to switch the electric fan on. If the fan still does not work, a mechanic should trace the voltage to the sensor and on to the fan. If there is no voltage to the fan the sensor may be not switching on the necessary voltage to the fan. The mechanic can test the fan motor by running two wire leads directly to the battery to see if the electric fan motor is working properly.
Any motor that overheats normally overheats the motor oil which naturally thins it out making inadequate piston ring seal. Overheated engine oil is more likely to be sucked down the intake valve guides also particularly if they are in need of repair.
Hope you get to the bottom of your problem!

best way to find out is un hook the fan plug in a meter crank the car and turn the ac o the fan should come on when the air is on it not givit a little run time till it heats up if you do get voltage check the resistance though the fan it its open you need sa new fan if you get no power. do the same thing but check thy resistance though the water sensor if it stays open then replace it. hope this helps good luck.

It works this way with any engine. The thinner the oil gets when heated the easier it is for it to make it past the rings to the combustion chamber and the quicker the rings will ware out from friction. So yes to much heat will kill a engine and cook the oil away.

Yes, if it was hot enough it could have damaged the piston rings. Or it may be just a one time thing, the oil was also above the temperature it was designed and formulated to operate at.
