BlackStone Comments: You have dropped a few miles from your oil change interval and wear still read about the same. Steady wear trends are what we look for in determining if an engine is wearing normally, and yours is. Silicon dropped to 8 ppm, so we don't think you've got any issues with the air filter or a silicone product in the system. The biodiesel isn't changing a thing--in fact, we have seen studies where diesel engines are proven to wear better on it. Considering the current cost of diesel fuel, we are all for alternatives! Your PSD looks great. Keep doing what you're doing.
Left column is current UOA and the center column is MC15w40 and the right column is Delo 400. I changed the oil early because I felt like it, I also was curoius as to it's condition. When not using B99/B100 I ran regular diesel with Stanadyne Lubricity Formula, might account for the increase in lead. This OCI was load at 24,000 GCVW for all but 300-400 miles. The silicon went down I think because I installed a Donaldson retrofit air box assembly [Ford AIS kit) which has a much better filter element and seal than factory. I was a little surprised to see the oil thinned as much as it did without much fuel dilution. With as much as this over-fuels at low boost I'm surprised the soot was low at .2% and the fuel dilution wasn't very high. I guess I'll go back to 4-5K OCI and be happy.
