What is the reason for replacing the crush washer?
Is this a Subaru thing?
I've never heard of doing that when performing an oil change (and I've changed quite a few hundred gallons of oil in my time).
So the filter threads are aranged verticaly/straight up which actually allows you to pre-oil the filter.....COOL! Don't see that too often today. Lots are angled and some are even upside down!
Does the filter cross to an aftermarket or AC-Delco PN?
What was the cost of the filter at the dealer?
