2009 Suburban - normal hot idle oil psi to rpm

Asked by GuruV1TT4 Jan 27, 2019 at 11:08 AM about the 2009 Chevrolet Suburban 1500 1LT 4WD

Question type: Maintenance & Repair

I can't for the life if me get a solid answer on this so I am
hoping someone can lay it out for me. What is the
good/acceptable bottom oil psi my 2009 Suburban 5.3 liter
should safely run at during a hot idle?
We had a low pressure warning at 10psi and it coded a oil
pressure sensor guage. We replaced that and now we dont
get the warning but the low speed/hot idle is still only at 12-
15psi.
Is there a standard psi to rpm ratio for this model that I can
count on?
