Very True Arco,
Take a look at Valvoline SynPower, 5w-40, SN as an example of GREAT base oil and a lower TBN. IMO...this is fantastic oil for the price and people run it for over 8K in their OCI with low wear numbers and plenty left in the add pack.
There are a lot of very good oils out on the market with exceptional base oils an they don't need a high TBN.

High CA will just cause high wear initially due to package surface competition. If you dont need a high basenumber oil dont use it. And Base stocks REALLY matter They are the difference between a ho-hum oil and a great oil. Period.
