Brian. Re: declining oil pressure as operating temp increases:
check the accuracy of your oil temp guage, then swap in a replacement
oil press guage, check its accuracy, You don't say what engine you're
operating but check the manual for a weak oil pump or an adjustment
thereto. Keep after this problem until you have swapped enough components
and checked enough variables. How much time is on your engine. If it's
old and weak, low oil press. at idle is sometimes to be expected. If the
engine is low time and running
strong you want to know what's causing this phenomena at idle RPM.

When oil is cold it will not flow as readily as when it is hot. So it
is normal for pressure to drop after the oil has heated. He said he
was using straight 100W not a multigrade, which alleviates this
problem somewhat.
His pressure may be low after warmup and need to be adjusted, but the
fact that it is higer when cold is not strange at all.
I cant comment on his reading since my guage doesnt read in potato's,
but I my pilot notes state
1.5 kg/sq cm min at startup
@ 1600 - 1700 RPM 4.7 kg/sq cm
@ takeoff power between 4-7 kg/sq cm
warm idle min 1.5 kg/sq cm
So it sounds to me like he's ok.
