I saw many Thread about this. I read a lot of them but... How to be really sure of your gage ?
The factory one is at the low line when hot after a highway run
The Canadien tire mecanical gauge with a nylon tube is at 30 psi at 2500 rpm and 5 psi at idle.
The industrial gauge install with a pressure line 1/4 '' made in rubber indicate 45 psi at 2500 and 20 psi idle
All is install at the same time
---------------------------
I change the little spring and piston that was made when I have to much pressure... .005 oversize and 10mm longer
I change the place where I connect those 3 gages Now the factory gauge indicate the pass over red line and the low line when hot.
The industrial one is always the same and the mecanical to. Maybe to much pressure at cold.
Do you have something to test you oil pressure gages ??
