I need to document one more bit of odd behavior, after the trip and I put her into park, the oil pressure creeps back up a bit. But only until I shift into drive again. Is that because there is no longer strain on the engine?
It'* because RPM, and thus oil pump speed, drops as you put it in drive and then into neutral. Ordinary.

So a good conclusion then is thicker oil for higher mile cars, with questionable oil pressure? Mine seems to run low also. 159000 and about 25psi at idle on the oil gage.
What is the recommended heavyer oil?

James...25psi at idle sounds fine. Don't need to worry in your case.

Thicker oil isn't recommended. Mechanical gauge is recommended. Find out if your gauge which we know has a certain amount of inaccuracy is over or under stating the real pressure.

Ok, got my pressure tested at the oil filter. In general, it was about 2 or 3 pounds higher than what my gauge indicates.
