TBN = 0 is not for the fainthearted, as the oil could corrode the lead bearings. Perhaps it's not a big problem in newer engines that don't use lead bearings. Let's see how the UOAs turn out. They said the early iterations struggled to get good UOAs.
It's a full synthetic, which is somewhat a first for a mainstream 15W-40. I thought Group III and GTL base stocks were rarely available in SAE 15W viscosity. There may be some PAO in the base oil as a result.
