TBN retention of Motul 300V Trophy 0W-40?

[dailydriver]

Since this oil starts life at a (relatively) low 8.something TBN, does anyone know just how well it retains it's TBN over an OCI which includes some fuel dilution?

Anyone using it yet, or done a UOA on an at least 7K mile OCI?

There is no indication from their site that it is a general purpose PCMO.

True, but MANY people do use it as a shorter drain (under 8K mile) street oil.

If it were really ONLY a PURE race oil it would have a lower starting TBN than it's 8.25
