Oil filter OEM Subaru or STP

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

Costco 5w30 synthetic with a genuine subaru filter every 3k miles lol

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.

I use the black OEM filter and Pennzoil Ultra Platinum. The platinum and the Ultra Plat is the same formula now I’m pretty sure. I’d stick to the OEM filter too. It’s what my tuner recommends and I wouldn’t go against what he says unless it’s literally written in the stars

Personally, I just use whatever is cheapest, as long as it is rated decently by the API. The way I see it, oil is really just oil. It's slick, it lubricates, it has whatever weight and viscosity it says on the bottle. The API makes sure it reaches those standards along with any claims on the bottle, so I'm comfortable saving money there. I've never had any issues in my many tens of thousands of miles of ownership and there's no sludge buildup or any worrying deposits inside the motor that I've seen when I've worked on it.

I am running an STP filter on it.

Put some normal oil and an STP filter in it. Got it all back together, runs great. Ran around the block, noticed the oil light flashed when over 2500 RPM . Back in the drive way, let it cool down. This morning, put motor flush in, idle it for 5 minutes per instructions, and drained the oil and changed the filter. Looking at the filter, it seems collapsed. It doesn't seem horribly clogged - there is a bit of silt in the crevices, but that was expected. Is it just because of the cheap filter?

When I first purchased my VW, I could drive it how ever far in whatever temperature and wouldn't get any beeps or blinks. I brought it to a friend to do an oil change and he threw 5W30 in it with a STP oil filter. After that oil change, if the car was driven too long the light would blink and the ding would chime. If you revved to about 2300~ RPM, the noises and blinking would stop. I guess that is a temporary fix, but all I did was change the oil to 10W30 and haven't gotten any noises yet. I guess 5W30 is too thin and can't build up enough oil pressure? I'm not too sure.
