I recently did an OC on my 2010 Subaru Forester. The Fram Ultra XG 6607 had been on there 9k miles and 10 months. It is never short tripped and does a combination of 50:50 city/highway 50 miles per day. The oil used was 5w-30 Mobil 1 + half a bottle of LM MoS2.
The filter had no issues and looked great. The silicon anti drain back valve was extremely soft and pliable.
