Don asked:<<did you change the oil when you bought the car, or is still
running the oil that the PO put in it>>
Hello Don of OK, ;-)
Oh, no, no , no ;-) The 1st thing I do when I buy a car is change the
fluids - almost always with Mobil 1 synthetic. We've put 15000 miles on
this car since buying it in Feb - last week was the 3rd oil change.
Also, with the car being driven 400-500 miles per week it's getting plenty
of exercize to burn off anything possible.
I strongly suspect the fuel in the oil was from the bad GPs which I fixed
last week. The next oil change would tell but I won;t do another test for
15-20k miles. Also, normally we see a lot of 1.0% fuel in oil numbers with
the threshold for Monitor at 5% and Abnormal at 6% - so with me at 3% I
really don't have anything to worry about. If you're curious about other
test results, take a look at

But I asked the list for possible reasons - and the suggestion about GPs
seems the most likely cause. Except for the internal IP problems - which I
sincerely hope are unlikely on a car with only about 100K car - the other
potential problems have been eliminated. I got a Carfax report on it when I
bought it and the mileage fits -
Thanks again for the suggestions -

Subject: Re: [MBZ] Fuel Content in Oil
Larry - did you change the oil when you bought the car, or is still
running the oil that the PO put in it? If it's still the PO's oil, it
will reflect his/her driving habits (could be a lot of short trips).
FWIW, the fuel content in the oil in two samples from the SDL at over
10K miles each, was <1%, as was the 240D at 5k miles. The SDL was
driven 40 miles per day, while the 240D was driven locally - lots of
short trips. The SDL engine is most similar to yours.
