My subjective opinion, based on my experiences, is different than yours. I've not had wear issues with Mobil 1 15-50. Thousands of miles trouble free, most of it since 2005 with the "new" formulation of Mobil 1.
would be a boring world if we agreed on everything...

Just because an engine has not worn out does not mean that the Mobil 1 in question had the same amount of ZDDP as it did earlier. Keith is correct, Mobil 1 15 - 50 DOES NOT have as much ZDDP as it once did. That is not anyones opinion, that is a fact that Mobil 1 has stated many times.
Most engines can still run fine with it though for hundreds of thousands of miles. That point does not speak to the levels of ZDDP for the average engine.
