Any way we could see the TBN (total base number) for each oil change? This is a true indicator of the condition of the oil and additive package when it is tested.

Also I noticed on the first change, the molybdenum ppm is high. This is an additive (and a good one at that).. If this was factory fill,,,I wonder what they are using in there!!

Interesting stuff, thanks for sharing
