Oil filter Mahle or Wix

I use OEM filters on both, but I’ll use Wix filters if I’m not around the dealer.

I bought a 10 Wix filters off of Rockauto. Part #: 51394. Each one was $4.80 and shipping was $10. Came out to be roughly the same price as buying OEM ones from a dealership off of eBay and I would rather use Wix ones.

Wix is considered to be good, and it’s not expensive and readily available (can walk into local O’Reilly and buy off the shelf). Subaru OEM works if you’re close to a dealership or think to order it; I never remember to order and my local dealer is terrible, so I avoid them.

Stick with the wix, rebuilders of rotory engine's suggest that brand alone. Given the necessity of the filtration needed for those engines, that's all I use for k20, 404xxxkm and running strong!

The WIX oil filer still included all the gaskets and a copper crush washer.

Pennzoil and a wix filter, 30 bucks total and 10 minutes of my time.

Then go buy a Wix. Or go to the dealer. Leave the cheap stuff (and Fram) on the shelf.

Engine is running smooth as butter and gets over 30 mpg on the freeway, so she seems to be fine with it

I use a Wix 57356XP filters and Mobil 1.

I supplied my own oil filter, a Wix 57002 for my 2020 6.
