Oil filter Fram or OEM Subaru

I use either Mobil 1 0w20, or Royal Purple 0w20. For the filter, I use Fram Titanium. I do all routine maintenance myself. I've got a 2015 SR DC with 388k miles, and have never had any issues. It still runs perfectly.

Not only is it fine, it’s widely considered the best option for the WRX. I have had multiple cars and always did my own oil changes. On my first oil change on the WRX I used my (at that time) tried and true Mobil 1 high performance oil filter and the seal blew and made a mess. Luckily I caught it before any damage was done. Since then I’ve exclusively used Subaru OEM oil filters and had zero issues.

Quality air filter changed regularly. Quality oil filter Frams higher end stuff are surprisingly well made for the $.

The OEM filter is not the best in any metric, whether filtration %, efficiency, or longevity. I'd say the OEM A01 filter is regarded as better built too but can be pricier and harder to obtain.

My recommendation would be Fram Ultra XG7317 which is a heavy duty built filter with synthetic media - I happily run this one for two oil changes at 6000 miles before changing.

These oils are only as good as the filters you pair them with.

I have seen Fram metal filters expand due to factory oil pressures.

Fram is absolutely the worst filters ever. Years ago a motorcycle forum I belonged to cut open a bunch of major brand filters, K&N, WIX, FilterPro (store brand style) Fram and NAPA. NAPA and WIX were the best bang for the buck, K&N obviously the best but also much more expensive. Fram was shocking, all the internals were cardboard, no metal reinforcement etc. Absolute garbage.

I had a FRAM oil filter on my 05 Impreza, I think the part number was #PH6607, I noticed i i was “burning” a ton of oil! I went to do my usual 3K Mile oil change. I noticed the oil levels were alot lower than the time i check a few days prior! I looked under the car and there was oil EVERYWHERE! Mainly built up around the filter!

I used a FRAM oil filter on the car at my last oil change and it turns out it collapsed internally triggering a low engine oil pressure to my ECU. The garage (VW/Audi/Porsche specialized) told me to never use anything other than Mann filters on my GTI since everything else is either gonna collapse or be more expensive than the Mann for no added benefits.

The cardboard construction on a Fram filter would have come apart.
