The topic is rapidly become like the tight bearing clearance fiasco - where the idea (M1 0W40 is better) becomes fact solely by constant repetition.

SFP,
Would you concede that the lead and copper readings have gone down with the 0W40 compared to the 10W60? I don't know about what you consider long term but the reports have shown less wear on the rod bearings with the 0W40. There is no denying that. As for iron, there has been high traces with the 10W60 as well. I think you like to take in what you want and ignore the actual test results.
