The 36 psi at idle is only for when it just hits 3 bars.
According to the manual... its after warm-up and at least 2 cooling fan cycles.
IMO that is way later than "just 3 bars"
They do spec 80C though, so if your 10W-30-dino-sheared-into-a-20-weight is 100C after 30 minutes you could be right about the 20 psi.

Ah ok didn't know that. Weird though. Pretty much everyone I talk to about it seems to have their oil pressure 20 or lower once fully warmed up.
Also I upgraded to the oil jet bolts which definitely lowers the oil pressure compared to a 2000, 2001 model s2000.

Could be as simple as a faulty oil filter. How many miles are on the oil change?

Not sure exactly. Probably 5-7k so guess it's probably time to do an oil change. I'll do one tomorrow and see if anything changes.
