My Last Oil Question!!! Lol

See thats just it...it is bothering me a bit. If it is closer to 20 psi, i would feel much better. Im sure the numbers i have now are ok, but i always look to make things better if i can, without rebuilding when i dont need to. The rest of the numbers at higher RPM's seem good, so i guess i shouldn't be concerned. I have the 20w50, so if the 5w50 synthetic isn't good, i will go to the petro oil and stay with it.
