Full disclosure the brand of synthetic I put in our beat old minivan was amazon basics. The good stuff!

I've been using (whether in the Outback or what I request in the boxster) M1. It seems that the "new hotness" for 9x6 and 9x7 motors (bore scoring) is motul 8100 x-cess gen2 5w-40, a couple of different versions of Liqui-moly, and Driven DT40.

Since my car is an S (more susceptible to bore scoring), I'm probably going to switch. It looks like the liquimoly and motul are $12-13/L if you buy per L, but down as low as $9/L if you buy in 5L jugs. It seems that the Driven only comes in qts or cases of 12 qts (assuming you aren't buying a barrel), and the best price for that stuff is $15.99.
