TBN of New & Used Oil

Read our primer articles on Oil Analysis and Tribology

Hello

Recently I have tested Lube oil from a Diesel Engine of a powerplant.

The Used oil TBN was : 8.564
New oil TBN: 7.452
Both samples were tested on same day.

Is this possible, I am little confused since I thought New oil TBN should always be higher.
Can any help me.
Thanks

Lubeboy,
Both samples are from the same manufacturer batch?
Did the user add some "perform" additives?

In addition, how about the identity and history of the used oil?
