I have just under 20,000 miles. A couple of years back on the DGR I had the oil get up in the 240-50 range. Since then my engine puts about 1.5 quarts into the sump after a few days sitting and it seems to get dirtier quicker. I also notice I need to top off the oil occasionally. I now drian the sump before start up and put that oil back in the tank, otherwise I fogged the whole neighbourhood
