I'm guessing you have CCV problems, which sometimes leads to oil consumption from what I read, the short trips in the cold that your wife does don't help. If you have paste under your oil cap its not being run long and hard enough to burn off the condensate in there.

As far as oil consumption, clean your engine out well, take a look for leaks around the oil filter housing, as well as feel under the valve cover to see if you can visually or by touch find any leaking spots, take out the spark plugs and see if they have oil on them at all, and obviously get under the car and check for oil spots by the oil pan gasket.


The M54 does consume oil, as far as I remember a quart every 1000 miles was within BMW spec believe it or not. I was about 3 quarts low on my last oil change, I drained out just under 5 and put in 8. However, my indy says no valve cover leaks, no under body leaks, no oil filter housing leaks. So if I'm losing oil it means i'm burning it within spec or through the CCV.
