Thanks for the affords answers.

The reason for my question about the final pressure of the oil pump is as follows: I have switched to an oil filter. Since I drive SAE 50 blocks the fine micronic paper filter the flow when the oil is still cold at 12 ° C.

That's why I chose a very large filter bowl that has a bypass valve. That opens at 18 PSI. (My pressure gauge scale ends at 10 PSI.)

Therefore I am interested in the pressure increase of the pump PSI/RPM to estimate how well it works with the bypass.


Mulletwagon: You can use a pressure switch. If the oil pressure gets at zero, a warning light switched on.
