Hi Mark,
I like to see 50 to 60 psi hot running down the road at 3500 to 4200 rpm. My
comfort level mninimum of 40 psi is also at 3500 to 4200 rpm. I really don't
care what idle oil pressure reads, but 20 psi or above is good.
I'm waiting for the response from members who will swear that the car only
needs 5 psi oil pressure as flow is more important than pressure. Some truth
to that. To those with lower than recommended oil pressure, I dedicate the
following verse written by W.H.Charnock, titled O.P.
O.P.
"Oil pressure at two thousand, hot, is forty pounds or so,
And if it is not forty pounds, your motor will not go."
Thus spake the learned makers in their clever little book,
And so, at that small instrunment, I seldom dare to look.
Sometimes on biting winter morn, when bitter frost abides,
The needle crawls to shaky ten, then sleepily subsides;
Oh clueless clot though I may be, is not this car a hero,
Have we not gone ten thousand miles, oil pressure, hot, at zero?
The Collected Motoring Verses of W.H.Charnock was originally published in
hard cover in 1959 and is difficult, and expensive, to find. However a
re-print titled Harry Charnock's Motoring Verse was published in 2002 as a
soft cover book. UK price was 7.50 pounds, cheap and a good book if you can
find it. No doubt also out of print??

Bob, At what RPM are you suggesting 50 to 60 psi hot? I take it you are
suggesting the minimum 40 psi at idle?
