Hi! I have a couple of questions about oil pressure. On my 1990 300 te the pressure when the engine is hot will be around 1 in N, and go slightly under 1 in D when standing still. It pops up to 3 at around 1500 rpm. This is all with AC off, turning it on will take away some more...

On a cold start it goes to 3, but it takes some seconds to go up when I start the engine.

Iīve always heard that itīs really bad to be under 1 no matter what, but my engine seems fit and good.

Is this normal and no need to worry?

Thanks! jm
