6k on the M1 0W40 and its TBN was down to 1.99 ! My recollection from other UOAs here is that the 0W40 generally has better TBN retention than what you experienced. Did you do some severe driving during the 0W40 use?
Nothing more severe than usual.

Not bad for an Energy Conserving oil, IMO!.................
The PU 5W30 seems to be a bit less prone to shearing than the PP 5W30, doesn't it?
Yeah, the PU seems to do really well for short-ish (5k) intervals.
