thanks. I am trying to be careful, thats why as you will note i changed my oil at 5,000 miles instead of the 10-15k miles interval mercedes recommends. Maybe i'm paranoid. This time i'm going to sample at 5k again and leave the oil in, and check the results again at 10k if the 5k results are acceptable. I bet they will have cleaned up since this test, as I do think that I probably could have taken a better sample.
I wonder if the use of biodiesel has thrown off any results also - should be noted that a few tanks of World Energy's biodiesel mixed at a 20% blend with regular petro diesel, were run in the car during the life of that oil. Burn the bean baby!
