Arco,
You are probably a bright and well educated fellow.
However, you do lead this board in your experience of obscure mechanical maladies.
Most of us will go through an entire lifetime of vehicle ownership without seeing the problems that you experience with any one car you own.
I honestly feel for you, since I have never had any observed problems with any car using any oil/filter combo.
I've never heard rod knock on any car I've ever owned, much less a new Subaru.
Heck, I had better experience with my MGB than you've had with modern, low-performance vehicles from highly regarded manufacturers.
My advice would be to avoid anything even midly complicated or exotic.
