Hi Paul,

As you know, oil pressure is a hard one to judge.  I think the
removal of oil pressure gauges in more modern cars is as much a
cost cutting thing as a question of not trying to confuse people
with too much information!

Anyway, there is one web page which lists some oil pressure
numbers.  It is at

http://members.aol.com/Fkc43/survey.htm

(I also don't drive around at 4000 RPM very much!)

On my very used engine, I get ~30 PSI at 3200-4000 rpm with
a hot (hot, not warm) engine.  If I go up a hill, the
pressure might drop to ~28 psi.  At idle immediately after a
hill, say, I will see less than 4 psi.  This is with an 80
PSI electric gauge, so the resolution isn't that good.  To
confuse matters further, I used to have a mechanical gauge
on that read a bit lower than the electric gauge.  I like
the electric gauge more because the numbers are higher!

Good luck,
