lower oil pressures with age

Anyone else ever noticed oil pressures drop with age?
I was rather surprised this summer when oil pressures seemed VERY low
when warm; lower than I remember. Sometimes below 2 bar at idle, and
it won't climb up to 4-5 bar until about 2,000 RPMs. Hasn't improved
with a new filter and oil. Used to be that it'd be dead on 2 bar at
idle when fully warmed up, and the slightest blip of the throttle
would send the oil pressure up to 5 bar; 1500 rpm was certainly
I had been told this is generally a warning sign of worn main
bearings- extra slop allows more oil to flow there. However, the
suddenness/change with oil change leaves me wondering if it isn't a
change in Mobil 1 oil.
Anyone? I've got about 201k on the clock.
