Recently, my '89 100Q has started reading quite different oil pressures
than it used to. Before, it would read about 5+ bar when started cold,
then eventually move to 1.5-2 bar at idle when warm, and 4-4.5 bar at
revs when warm.
Now, it starts at 4-4.5 cold, and sits at 2.5+ idling when warm,
4+ bar at revs.
This seems to have happened right abuot the time of my last oil change.
I use the same Castrol 20W50, and the same OE+ filters (with anti-
drainback valve as always). What could change this long-standing behaviour?
Clogged filter? Clogged line? Incipient oil pump failure? Driver paranoia?
