My 88 generally doesn't show over 25 psi at any time. Could be the gauge, sender, or the 200k miles on it. Don't know, don't care. As long as it isn't 0psi :ack: (happened twice now, once from the rms leak and once due to a fram oil filter :fs1: ).
I'm not saying yours couldn't be better, but it's possible that you're over-thinking it. :D
