Oil filter OEM Subaru or AC DELCO

AC Delco OEM filter is all I have used on my GM trucks in a long time.

I also use an ACDelco filter (blasphemy, I know).

Wait until you change the filter on a Subaru where the filter is upside down.

Absolutely not. Example, I was an equipment manager at a Petroleum tank company. On our generator I tried to use several different manufacturers and the all blew the seals out because of filter material and pressure valves they used. I ended up buying OEM filters and never had a problem after that.

Oil Filters, I always use OEM Subaru oil filters, I just buy the bulk 12 pack from my dealer.

people are really set on the subaru filters as opposed to fram or others, and they’re really not very expensive so i just do it.

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.

the local gm dealer here uses the cheap delco filters and they always make my oil pressure drop 10psi

For oil filters I feel like the ACDelco filters are pretty low quality and there are many better options. Mobil and K&N oil filters are available at Walmart for $10-15, made in USA, and seem to be much better quality.
