Looks like you never need to change the oil!

I will just change the oil filter and top off the oil.

That is a really high TBN for having that many miles on it. Wow!! Wonder what was the TBN in the virgin oil?

 

[ovidiu]

The TBN is 10.8 here is the pdf file http://lubricants.petro-canada.ca/pdf/DURON_Synthetic_IM-7944E.pdf

is the EGR still working?

 

[ovidiu]

Yes the EGR is still working. The Lab where i did the UOA is Oelcheck in Germany and they usually show higher TBN than Blakstone Labs.
