This UOA was recently posted on Vortex. Assuming this is regular use, this UAO is outstanding IMO. Shear is lowest we have recorded on this engine at 5% in 4000 miles. Flashpoint retention is superb. Metals are very low. I don't normally post other people's UOAs but this one I think people need to see.
We need to verify that this was not an all-highway run and that it is needs to be tested on more engines but extremely promising results! (Note if run all highway, it is hard to tell much other than the low shear becasue all highway runs on this car look good with most any oil).
Here are the Brad Penn specs:
