Oil filter Wix or AC DELCO

I've used Fram, Supertech, Denso, O'Reilly or Autozone store brands, WIX.

Pennzoil Ultra Platinum 0w/20 with Wix/Napa Gold filters. -been relentless about 5k services, @45k now.

-just received my first ever Blackstone Lab analysis, TBN numbers were still extremely good. Blackstone advised me to push my next service to 7500 miles.

-the oil that was sampled, was still a very light Carmel color - I feel guilty throwing away oil that still looks this good

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.

AC Delco oil filters are now all made in China (but they won't confirm nor deny this), so they have a single package for all markets they serve.

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.
