Oil filter Wix or AC DELCO

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

Absolutely not. Example, I was an equipment manager at a Petroleum tank company. On our generator I tried to use several different manufacturers and the all blew the seals out because of filter material and pressure valves they used. I ended up buying OEM filters and never had a problem after that.

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.

Wix or the Black Mazda filters.

I would highly recommend Rock auto, there website is simple old school but they are no bs auto parts store and will only show what does fit. They often show the real part your buying (say for tie rod), I've bought thousands of $ of brakes and suspension components over the last 20 yrs and always correct, they often sell OEM parts or the direct suppliers version of OEM which is unique. It will take some time for most of the aftermarket parts for the CX50 but at this point WIX or OEM Mazda are going to be your best bet for oil filters

If you're going to go aftermarket, the Wix/Napa Gold filter is also designed to meet Mazda's specs.

If you want to go aftetmarket I recommand using WIX filter they are good stuff

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

Had a WIX 57312 instead of a Motorcraft EC-781. So yeah, it fit but it was allowing oil to bypass the filter completely.
