1st UOA was done on factory initial oil fill, unknown type of oil. Refilled with LubroMoly TopTec 4200 5W/30.
I did not do a UOA after the second oil change. Refilled with LubroMoly TopTec 4200 5W/30.
2nd UOA was done on the 2nd run of LubroMoly TopTec 4200 5W/30, obtained by the dealer and refilled with Castrol SLX Professional LL03 5W/30.
3rd and 4th samples were obtained by the tech at the dealership and were Castrol SLX Professional LL03 5W/30.
The last 20K miles been running close to 4-5% Biodiesel along with 4-6 oz of Optilube XPD.
I was finely "relieved" to see the wear metals come down.
I'm going to do a cross country trip soon and will change the oil at 10Kish. I'm going back and use the Lubro Moly TopTec 4200. I'll monitor the wear and TBN to see if I can stretch the change out past 10K if TBN holds up. Not sure its going to though.
