The "specs" might be adequate. Problem is, the specs don't include some of the debris that is actually being put in the finished product.

Catastrophic failure is hardly a meaningful measure of oil filtration effectiveness.

Agreed. The dual-chamber filter system (in which some oil is continuously filtered and returned to the oil pan) is superior to a simple pressure-path-only filter. For diesels, it was thought that removing as much soot and other combustion products from the oil was important (and it is!). That's probably one reason why it's possible for these engines to last so long. It's also more expensive and probably why Mercedes chose to drop it in favor of the simpler system. Why give the customers prime rib if they're happy with hamburger?
