TBN looks low as well. Wonder if there are other ingredients in motor oil chemistry oil base oil chemistry that B/S labs or other are not catching and its time to re-look the oil analysis playing field.Additive levels and viscosity look a bit low. Unfortunately B/S labs isn't that good. Thank you for sharing it though. Looks similar to a PUP VOA I saw recently that was API SN. Additive composition is similar to M1, with PP having more Boron. GTL based.

I think this is an UOA of the SN+ version:Quite a few VW508 0W-20 motor oils are very thin at 100*C. These oils are scheduled for 10K mile intervals. I have no doubt PP is up to the job regardless of the 8.01 viscosity.

Pennzoil will back your engine for 300k miles using this oil, so I'm sure they have done their homework. If we've seen anything from recent engine failures that have resulted in extended warranties and/or large-scale replacements, it's poor mechanical engineering that has sealed those engines' fates, not the engine oils that meet the required specs.The oil is quite shear stable but a thinner oil is ultimately still a thinner oil. There is less reserve in a more demanding application that can cause the oil to deteriorate (fuel, viscosity breakdown, etc).
