Post Oil pressure
I am curious about the level of oil pressure we can expect in the 2cv engines (602 and 652 cc). I have installed an oil pressure reading gauge. At idle I measure 20 psi (1,2 bar) and at around 4000 rpm, it is 60 psi (4,4 bar). Anybody has same experience ?

From https://www.citroenspecialsclub.org/pub ... /page1.php

After starting the car and left to warm up to a steady idle the readings were 115 psi at 6000 rpm 90 psi at 3000 and 50 psi at 1000
I then went on a blast for 1/2 hour reaching 60ish mph. After this the readings were 90 psi at 6000 rpm 60 psi at 3000 rpm, at idle the reading was 20 psi dropping to 15 psi after a couple of minutes.

According to Haynes manual:

A79/0 and M4 35.5 to 44 lbf/in2 @4000rpm
A79/1 57 to 71 lbf/in2 @6000rpm
M28 and m28/1 78 to 92 lbf/in2 @6000rpm
