I scored 115 QTs of 0W-20 and 80 QTs of 5W-30 for the AAP RGT sale and have decided to run it in a 60/40 mix. A VOA of the mix for any who are interested from Polaris Labs.
My 5K run had the TBN at 2.68 (down from 6.44). My viscosity also sheared a bit from 9.6 to 8.7, meaning it started as a light xW-30 and ended as a heavy xW-20. There was 3-4K RPM sprints for miles during the 5,500 mile road trip where the 3.6L would downshift to 6 or 5 to maintain the 75+ MPH speed in headwinds and mountains. Despite that, the wear metals were good as was the gas mileage.
All in all I am happy with RGT (heck, I better be--200K worth in the stash).
