"newer oils are probably superior in most ways...but are lacking in some other aspects."
Exactly. Lacking in ZDDP.
If you have an old engine that relies heavily on ZDDP's protective properties then a newer engine oil with only 600-800 ppm of phosphorus will cause excessive wear because the next generation additives don't work that same way that ZDDP works.
The B234 isn't that sensitive, so many 9000 owners have been rolling the dice and getting away with it. So far.
