I was under the impression that synthetics don't use VIs the same way conventional oils do.

The source I cited in post #13 above claims Group 4 PAO based synthetics do not need VI additives. It is the Group 3 types, of which Mobil 1 is an e.g. (though a good oil that I am running right now) that need them because they are not strictly absolutely synthetic. Group 4 synthetics should not, therefore, have this break down problem, no?
