Oil filter Wix or OEM Mazda

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.

I personally do an old and filter every 6-7000 km. I do it so frequently because, 1) I do it myself, so cost is down and I make sure the job is done right. 2) the sky active engines are known for carbon buildup, so more frequent oil changes should help. 3) Longevity, I want to see 300,000 or more on the dash one day.

People like me on the other hand are going for synthetic oil and Mazda OEM filters but still need to get an oil change at 5000 miles.

An oil change with decent full synthetic is 30-40$ for 5 quarts + OEM filter for another 5-10$. It's relatively cheap to do every 6-8 months to know it always has decent oil, and no problems should arise.

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!

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