06 LBZ oil PSI

[Kartmnn]

What should a lbz with 114xxx miles hold for oil pressure? When its hot the pressure is around 25 on the gauge at idle and at about 1800rpms its holding around 40. Anything over 2000-2100rpms it jumps to almost 60psi. Last oil change was done at GM dealer with whatever oil they use. thanx

Sounds about right to me.

It may be less then 40 at 1800 because I drove it today and it looked around 35. Motor runs great so I dont know...

Do you have EFILive or know someone who does? If so, you can datalog oil pressure. The gauge sometimes leaves a lot to be desired.
