It looks good to my amateur eye. I know that PUP 5w30 starts out on the thin side of 30 wts. but it has sheared into 20 wt. territory in 5K. It would be nice to know the TBN to see if this 'premium' oil could go further.

Id be curious to see how a different 5w30 or even a 0w40/5w40 would do, in terms of shearing. Might just be me but id want to find something that stays in grade during whole OCI.

Agreed. A 0w40 wouldn't hurt one bit.

No plans to run intervals past 5k.
