It looks like they thought it was Mobil1 5W30, but it was Mobil (not 1) Clean 5000 5W30. Would that change their analysis of the TBN?
Still, it's good to know 13000mi is too far on conventional, at least for your car.
Hmm, this makes me want to see a UOA on Christ's engines with t-shirt air filters.
