There are a million used oil analysis on RP, here's one. Oil was still good in a Denali with 100k miles on ODO after 10k miles on RP. Every Synthetic will hold TBN better then your Dino. So extended oil intervals will be fine based on the oil still having additives (TBN) in the oil after a long time. The two knocks on RP is wear tests and evaporation, and I say knocks only when compared to the best oils. RP is fine stuff, and there are other benefits to using it like great viscosity for cold starts and a nice film that adheres to metal, plus the best price I can get on my oil is 125 bucks shipped to my door.
