major oil leak!

I would check the oil pressure sender and 1.8 bar oil pressure sender.
If I am correct the 1.8 bar sender is closest  to the front of the 
engine, down under the PS pump
Both are on the left side under the intake manifold.
It is possible one of them died and is letting oil through their bodies.
With the oil pressure fluctuating that would be a good place to start 
Since you had to add engine oil I do not think it would be the PS pump.
