OK, we've seen some excellent reports with M1 and some that show higher then usual Iron. Mobil 1 has the same amount of ZDDP as GC and Chevron Supreme, yet these oils show slightly better wear. While it's not enough to cause premature engine wear IMO, does anyone think it's a Viscosity issue with M1 or is it a ZDDP issue?
As I said above, there are other oils with the same level of ZDDP that do was well or better sometimes. It makes me think that Mobil's lighter viscosity is it's dowfall, rather then it's additive package. M1 has a generous amount of Boron, Calcium and Moly. In fact, it's additive package seems more advance then Amsoil's. I'm curious to see if M1 would be better if it were thicker like Amsoil or GC.
