Thanks for the comments.
I didn't do a TBN as I only wanted this as reference to compare with the brand I replaced it with. I just assumed that the PAO MC oils were good for 5k.
In regards to the "thickening", I am not sure what to think. By reading other UOAs, it is evident (unless I am missing something) That M1 Vtwin and Amsoil MCV 20/50 will both end up on the heavy side on a 5k OCI. Whether that is good or bad, I am not sure. But.... wonder given all the material avaiable that extols these oils as rock solid Best of Breed, whether or not they actually live up to their own standards.
