I was just wondering what oil, and oil filter do you guys recommend? Thank You

5w30 oil; Subaru OEM oil filter & crush washer.

5w30, synthetic after 5000 miles unless you plan on changing it religiously every 3000 miles, Subaru OEM filter or Purolator filter. For better filtering, you can use a Forester filter, more filter surface area, same other specs. New crush washer every time.
