85 300d -i just changed oil and filter ,noticed oil pressure at 3 with idle at 750 upon starting,when warmed up after 15 minutes pressure drops to 2-2.5 at 750.i dont recall oil pressure remaining at 3 before,is this normal ,can it be a funky filter-i used a mann filter and know its the correct one.maybe i just never checked before when changing filter and this is ok.

Its normal....

If during your Oil Filter change you also changed the 2 little O-rings at the bottom of the Oil Filter Cap Stem it may be sealing better down there and raising the idle oil pressure.
a hot oil pressure at idle of 2-2.5 is good. Mine is about 1.5 bar.
