Toyota 2.5L 4 cylinder, non turbo. OCI would never be more than 5,000. Trips would vary tremendously from city (5 miles or so) to 1200 miles on the highway continuously.
Just about any API licensed house brand would easily suffice. There is no reason to spend a lot of money for that application. Even if it's GDI, your planned OCI is short enough that fuel dilution would be moot.
Seriously; you're overthinking this. Your engine, based on the described application, will NEVER see any difference in wear control regardless of what brand/grade you choose.
Anyone who says otherwise I would challenge to show me real world true data from macro-market applications that what I claim is not true. (Shade-tree anecdotal war-stories are not credible "proof").
