Sudden shift of oil pressure from 4.5 bar to less then 2 bar over 2.5 months 200 1990

In my experience- no, low oil pressure would not make the engine run rough, although they may be linked in some way.
If a failed bearing is causing excessive friction for example, but I would expect that to be very noisy.

Oil pressure of 15 psi would be enough to keep the bearings lubricated, the key thing is the sudden drop in pressure which I would associate with increased clearances somewhere in the lubrication system. Often is excessively worn bearing or oil pump.

It's not the oil pressure which prevents metal to metal contact, that's done by the oil film which 15psi should be capable of supplying.

Just my opinions of course,

Ian F
