it's not running low, that is for sure... Jumps right

If you needed to know that the pressure was 6, Mercedes could have given
you a gauge that read 6! They give you a gauge that carefully reads
where oil pressure is critical - between 0 and 3. You NEED to know that
the pressure is at least 3 when the rpm is 2500-3000 rpm or higher and
is always above 0.5 at idle. That's the critical range.
You SHOULD be sure that the oil is suitable for a diesel. I recommend a
CF or better rating and an xW-40 or xW-50 rating (CH-4 thru CI-4 rated
oils are probably a bit more desirable, but that's hardly critical). The
"x" should be some number between 0 and 15 (I don't know of a diesel
rated 20X-xx oil but there MIGHT be one there somewhere). Most
conventional diesel rated oils are 15W-40. In MY OPINION the best of
these diesel 15W-40 oils are Chevron Delo 400 and Mobil Delvac 1300. The
others commonly available in the US (Rotella, Exxon, Castrol, etc.) are
inferior, rather ordinary, but can certainly provide suitable lubrication.
