I got more responses that I expected. This afternoon I'm going to put a manual oil pressure gauge on and see what it really is
That's the only and right way to find out
if there is a problem.
10 psi at idle wouldn't bother me as long as the pressure rises as rpms increase. Some motors are good to go with as little as 20 psi @ 2000 to 2500 rpms. Instead of additives run 10w 40w and replace the filter. Oil filters can cause variance in oil pressure but usually on the high side.
Low oil pressure is not necessarily a sign of worn out bearings and that the motor is on its last leg. I'd look for other issues way before considering that diagnoses.
Ignore all the other BS I posted. I was just having fun with the variety of posts made that weren't on track.
