It was about 35 degrees this morning. 240D (with goopy mixture of Kero/D2/oil/etc) started on the third crank. Ran fine, as always.
After about 15 minutes of driving, I noticed that the oil pressure was not at 45...and that it was flopping all over. Up, down...up when slowing down, up when idling, up when accelerating, down when accelerating - all over the place with little rhyme or reason. Pulled over and checked the oil level with the car running - it was over high. I have not added any oil since the last oil change. It doesn't leak at all, nor does it burn, that I know of (M1 15W-50, BTW). Oil was black and did not notice or smell anything like coolant (will check that later once all has cooled down). Will also check engine oil level later once all has cooled down. Got to work and in neutral, did get rhyme or reason out of it. At idle it would hang around 20 or so...but I would have to get it to 3,000 rpm or so (guess, no tach) before it would peg 45. At least this was consistant. Question: What might be going on? If it were the oil pump in the engine acting that crazy (i.e. BROKEN), would I be able to tell by how the engine ran? Has my oil pressure guage gone goofy? Thanks for any ideas.
