Factory spec says minimum 0.3. In practice I only get worried below 1 bar, and and the actual oil system failures I have encountered were definitely not gradual, more like a couple twitches and then zero.
1.5 is not alarming enough to shut down like that. Pretty much where my hot idle is all the time. With most benzes it's a bit closer to two but 1.5 has not bothered my particular car for the past 40k miles.

it should be pegged at 3 above ~1500 RPM or so... but 1-2 idle at N.O.T. is fine... if you see it drop while revs are up, then thats something to worry about...check oil level, likely low if that happens or theres a catastrophic leak, which I guess would make it low too...

(11-20-2012, 11:46 AM)Siekkinen Have you changed the two o-rings that are at the head of the oil filter housings pin? They made a difference on my oil pressure.
Check those orings-every 61X engine I've worked on those orings were so old I thought they were black plastic and crumbled pretty easily

larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?

I have never seen any, though I have seen the grooves. Maybe they have disintegrated on my cars and I never even knew it.

You mean at the tip of that tube that goes through the filter? They are supposed to be rubber rings on there?

Yea, that's exactly what I ment but I just couldn't explain it understandably. There really are supposed to be two rubber rings. They affect the oil pressure. My oil pressure used to be about 2 bars on idle and then I changed the o-rings and the oil pressure increased to 3 bars.

zomg, I had no idea. Got a part number? Link? Actually the hardware store here has loads of o-rings. But I don't know if I could pick out a good fit.

I just left them alone. Maybe I should look for a replacement and crack them off.

I just had a look at my filter. Those rings were there and they seemed to be hard plastic. Not so much a rubber o-ring. I am confused as to how they got on there. They seem super hard and I can't imagine how they could stretch to fit on.

Replacing those o-rings probably helps you with your pressure problem
