Just writing to say thanks for all your responses on this.  I agree with
Jeff S. that there can naturally be a lot of speculating in responses, but
in vehicles that seem to be outliving the planned utility of their
manufacturer, it's all we have.  So any info can be useful, even if it is
pretty subjective or dependent on unknowns in an engine's specific history.

It seems the broadest consensus seems to be about knowing your oil pressures
and temps, and drive accordingly. So for me, anyway, I'm gonna move in that
direction.

Thanks all,
