I ordered a (4 Pack) of Subaru engine oil filters & crush gaskets through Amazon for my 2018 Subaru Outback 2.5 4 cyl non-turbo engine. The crush gaskets were 17mm rather than 13mm which were on the drain plug which caused me to check the specs on my order. I had ordered part# 15208AA12A filter and gasket Genuine Subaru 1990-2018.
I rechecked the order and discovered there were different filter gasket combinations for different models with the same engine and mine should have been a part #15208AA15A instead of 12A. The crush washer was OK for reuse but I am wondering about the difference in filter and if it can be left on and used on my vehicle or the oil changed at an earlier interval, or I should replace the filter with the correct #15208AA15A. I used Subaru's recomended Idemitsu Full Synthetic 0W-20 Engine Oil SN/GF-5 - 5 Quart and perhaps I have 3 filters and washers available.
