Per SMS:
Which TDI is this? Is it the same one that VW uses in the diesel cars
that they sell in the U.S. (not in California though).

Apparently not, bc I got it wrong.

It's actually "Mercedes-Benz CDI turbo diesel engine" per Freightliner's web
site. The site is sorely lacking, however, in details.
