Oil filter Mann or Wix

I always do Mann filters when available like temporary-republic-6 said it is the OE filter. Also some independent companies have cut and tested different filters and found Mann has the largest filtering surface. I been using mann for roughly 20 years now.

I do every 3-5k miles, with Mann oil filter, both o rings, drain plug and washer, 7 quarts of 5w-40 liqui moly Leichtlauf High Tech oil.

i keep using wix and haven’t had any issues

Subarus are honestly for the most part pretty easy to work on. Oil + filter changes are very easy. 30 ft/lbs, only use oem or wix filter imo

DIY. Kirkland 0w20 full synthetic 5qt - 4-pack (20qt total) for $70. Buy a few WIX oil filters off Amazon for $10-12 each, and for $100 you can do 3 oil changes in your driveway.

Use an M56 filter, it's slightly larger. Been doing it for over 2 years. Over the counter Pennzoil Ultra Synethic 5w30 is fine, I use Redline 5w30, it's slightly thicker at temp. For a filter, you can't really go wrong with Wix, Mobil, or Fram Ultra. If you watch a tear down of any of these, they're all virtually the same. Fram are built in America and readily available, the Nissan filters are covered in glue and made like total crap in my opinion. But those three should be made in America. Lots of oil filter brands use Fram filters and slap their name on it, Wix too in Napa's case. If you change it every 3,000 miles you can basically use anything as long as it's a quality filter. Personally had nothing but good things to say about Wix and Mobil. Only annoying part about Fram Ultra is the stupid grip they put on them makes my filter wrench slip right off.. But I've used all three and had no complaints.

I have used Mann Filters and Valvoline European 5w40 since new. I have gotten the OCI dialed in at 6500 miles.

I found a shelf full of Made in Germany Mann oil filters for my BMWs that is OE for the N55, N54, N52, N20 engine that were 80% off and ran up as $2.78 each. I cleared cleared the shelf full of those filters.. And i also found a new starter for my NA miata $11 that I was planning to replace . It was 95% off.

Have you considered checking oil pressure regulating valve? In the past I have replaced pretty undamaged filters when I did oil changes. But for the last three years I get crushed filters out of the housing.

Wanna see what a Wix filter looks like after less than 10k and 1 year of driving. Notice how the paper media pulled away from the rubber support. Notice that the filter has been sucked in.
