So I've been seeing a lot of talk about Magnatec in the UOA's and PCMO section. Is this the new "in" flavor? How does a 5w30 Magnatec hold up to, let's say PYB of the same viscosity? I do 5k oil changes in the 5.4 3v and intend to keep it that way. So the question is, is it worth the little extra for Magnatec over PYB for 5k OCI's?
