OK, now back to our regular programing ...

This is a DI engine right? If so, there is some concern about calcium, is there not?

I'd be a bit more careful than "Any XW-20" at wally world with a DI engine.

And, if it's going to tend toward some fuel dilution, I'd be real careful about a "skinny" oil. So I'd be looking at modest HTHS for the 20 grade at op temp, the right chemistry for DI issues, and I'd be changing oil every 5,000 as it's easy to see and remember

I don't think so. Not unless Subaru has changed the FB in the last couple years. I can't see anything mentioned about DI in the engine specs shown on Subaru.com.
