We do oil analysis yearly, but this is the first year we've had TBN tested. I'm surprised that the values are still this high after all these years.

Ho-lee crap man!! Thanks for contributing these. Not the usual stuff we see here on the boards. Yeah, TBN looks awesone. I don't know what to make of the oxidation number. Have the years taken their toll? Maybe.
