Mobil 1 would have more iron than this in half the miles.
Why do you find it necessary to bash?
Last year I did a UOA on both cars at almost 10,000 mile OCIs. The Merc was 22PPM on iron, and the Focus was 11PPM both on M1 oil.
ZZMan, your report is fine on the Castrol Edge. You might get another thou or two but not much more.
