Oil Pressure with M10 motor

[Hans]

What sort of pressure readings are people seeing - hot/cold, idle/4000rpms ?

Do a search....there is lots on this topic.

I see about 90 cold and 60 at freeway speed hot. It drops to 20-30 at idle when hot.

Confirmed.

Depending on what weight oil you use, can change that 5-15lbs. idle - hot
