Hi RevRider,
I'm coming in late on your thread but want to say I liked your oil filter selection hierarchy. Here's mine based on a comparison I did last week and both the Purolator One and Fram Tough Guard are superb values for our Subarus. I use both in my 2021 Forester.
1. Filter media performance
2. Silicon anti-drain back valve
3. Mileage rating, i.e. robustness
4. Made in the USA.
