A few of you may have caught some of my oil/filter research and I ended up going with Mobile 1 extended with a royal purple filter. When I changed it, I caught something that had me doing more research...the filter is tiny but the space has plenty of room for a longer filter. The problem is I don't know enough about filters so I searched around and found this:
https://allwheeldriveauto.com/subaru-service-seattle-subaru-oil-filters-explained/
Essentially, with the newer ducting (I have this) or with turbos, a larger/longer filter would be too close to the exhaust pipe and increase the engine temp. The author also mentions that the small filter won't last long due to the size, even synthetic. I can buy this argument but no evidence to really back it up.
So now I'm thinking, drop the oil change interval and/or at least the filter change down to 5k for simple change math to avoid a failing filter. I'll find out if the oil can remain if it dumps too much out...but I'm pretty sure I can go with just the filter. Anyone have any thoughts/recommendation to add...besides doing the test, which I will do at 5k.
