560 oil consumption
Here is a mysterious one:
1991 560 SEL with 62k miles in excellent condition, service history, etc. is burning about 1+ quart of oil per 400 miles. Topped off 1/12 quarts last week and reset the tripometer....425 miles later the oil light came on.
Car runs fantastically, gobs of power, no smoke whatsoever.
No leakage whatsoever, no oil in coolant system.
I am aware of valve stem seals being problematic at much higher mileage, but??
Any direction here is much appreciated, though I am thinking compression and leakdown tests are in order here.
