Oil pressure

What is normal oil pressure for a 4.0? My old 258 would run at about 20psi. I got my 4.0 wired in and it seems to run at 40psi. I like the looks of that a lot better

Mine runs between 40-50. Mid to upper 40'ish when it's fresh and around 37-40 when I need to change it.

Running 20W-50, I get 80 psi cold, and no lower than 40-45 psi at its hottest.
