This is the Subaru of America OEM oil filter for H4 engines. It came off a 2008 Subaru Forester 2.5x (Normally Aspirated) with 57,000 miles. This car sees a good bit of stop and go rush hour traffic and highway miles. This filter ran for 4,061 miles which was accumulated in just over 2 months. The oil used was Chevron Supreme Conventional 5W-30.
I let it drain for a couple hours and still the ADBV held back a considerable amount of oil. As I cut it open oil began spilling out everywhere.
Here's the components. Everything was put together very well and there were no defects observed.
Ahh yes, the dreaded 'engineered media' endcaps!
Actually, the endcaps are sealed extremely well to the media. This is the fourth Subaru OEM filter I've opened and they've all been excellent.
Here's the typical gap at the connection point. All of the pleats are sealed in-place and no ripping, deformations, or media collapse was observed.
