Is that the recommendation for synthetic for your engine? I'd have
thought much longer.

The Ford (Navistar) 6.4 diesel and really all of the new generation of
emissions controlled diesels have higher maintenance requirements than
the old generations.

There was a real sea change in diesel technology that accompanied the
emissions controls, mechanical injection pumps were replaced with high
pressure common rail electronic injection, basic turbos were replaced
with two stage turbos with servo controlled variable stator vanes, etc.
All this change give significantly higher performance than the old
generations, but needs more care.

I'm particularly anal about maintenance on my $60k truck ($15k engine
alone) and I'm pretty happy with the results. I do oil analysis at every
oil change and my reports are some of the best seen for a 6.4 per the
various diesel forums. I'm not going to skimp on maintenance to save
perhaps $200/yr in oil and risk a $15k engine as a result.
