Diesel Oil Pressure

Mar 15, 2005 5 Replies

Can't figure out why my oil pressure stays above 30 psi at warm idle on my W115 240D (616 4 cyl. diesel). Always before, I've seen it down below 15. Of course that was on cars with more than 250,000 miles.



Is this cause for concern, or rejoicing?


My '80 300SD has 1.75 BAR (25.7 psi) oil pressure at hot idle (after

108K miles).

That's very close to what I'm seeing. Just rolled over 98K miles.

That's just about what my '74 240D with 20/50 weight oil shows at idle, Randall.

Great. That's a relief. I am used to engines with much higher milage.
