Old stuff? All the Castrol 0w40 UOA/VOAs I've seen in the past year or two have had high Ca, low Mg. Where are you getting your information? VOA or UOA somewhere you can cite for us?
Castrol 0w40 is one of the most tested, highest performing oil on the market today. It's KV100 and HTHS are really not too high for something Ford says needs 5w20. Puzzling results.
Viscosity looked OK for all the oils (0w40,5w20,FF), even though some fuel dilution knocked the 0w40 down to a 0w30 there, it was still safely above Ford's spec.
A lot of engines that show fuel dilution like this don't have high iron, so thats not whats doing this.
