So, what is "too much" oil pressure in a waterboxer?  mcneely

And, what is too much oil pressure in an inline VW motor?  (ABA Jetta 2.0
liter)

 Mine, using 15-40 starts up cold with (3000rpm) 75-80psi, then when up to
normal oil temp (~200f) the pressure settles at around 60-65psi (again,
given a 3000rpm engine speed)  I've wondered about the seemingly pretty
high cold oil and engine oil pressure...

   After hard use on a hot day, my idle OP sits at about 25psi with the
15-40w oil.    When I use 10-40 or 10-30, I see about 10psi lower at speed
and a few psi lower at idle when hot.
