Oil filter won't fit

:
CX5 GT
I have changed oil before in my 2016.5 CX-5.

I used Wix filters but today I've tried Wix 57002, STP per Autozone then a Mobil-One 1-108. None of these will fit. The threads are too small. Am I losing my mind?

Sorry if this is an old topic but it doesn't make sense...
 
Mobil 1 M1-M108A
NAPA FIL 7002
Wix 57002

All should be correct filters. If you are saying the threads are too small on the Wix and Mobil1 then I cant say bad packaging. Perhaps a side by side photo of the old filter and new filter(s).
 
The oil filter uses a common pipe thread size and a number of filters will screw on.

We shouldn’t list Mobil 1 M1-108A as a correct oil filter for SkyActiv-G 2.5L, and even 2.5T as suggested on Mobil website. Principle applications of Mobil 1 M1-108A oil filter listed on Mobil website are Hyundai, Kia (1994-10), Infiniti, Nissan (1995-16), Mazda (1990-08, 2011-16), Subaru (2004-15) (Mazda B6Y1-14-302, Subaru 15208-KA010), yet M1-108A is listed for SkyActiv-G 2.5L and 2.5T for all CX-5’s up to 2020 MY. We know 2.5L and 2.5T use different OEM oil filters. And Mazda part no. B6Y1-14-302 is an old OEM oil filter used on earlier Mazda2. In addition, Mazda had sent out a memo a while ago that B6Y1-14-302(A) can’t be used on SkyActiv-G engines.

Mobil is a major, highly respected maker. I wonder why they haven't addressed this?

Also aftermarket parts manufactures usually use one-size-fit-all attitude to save their cost. They don’t really care the products really meet all specifications of original OEM parts, as long as they fit.
 
thanks @yrwei52 for the insight. I went ahead and linked your post in the knowledge sharing document so a person can make a decision for themselves which product they may or may not want to use in their vehicle.
 
I'm running the Mobil M1-108A filter. Comparing to Mazda filter, I recollect there is only about 2 PSI difference in bypass pressures and the Mobil 1 has finer filtration. In past cars, I've seen 80-100 psi oil pressures with really cold oil and winding it out, so 2 PSI is moot. Have to remember that bypass is going to occur in cold weather at startup with either filter, and once warmed, the flow is through the filter so the bypass is out of the picture at this point anyway. Are there really any other differences that would require the use of a Mazda filter.

The choice is yours.

That 108a filter has been around for a long time - it's listed as the recommended model for a 2004 Subaru I own. As you said, the OEM and aftermarket filters sometimes have different bypass pressures, but if it really is only 2psi different from the OEM it's probably fine. In the case of the Subaru however, the bypass pressure of the OEM part is double, so it's not quite an exact match but they list it as the replacement anyway.

Thanks yrwei. I wonder what this mysterious "difference in internal construction" that Mazda alludes to really is, unless it just has a lower flow rating. In a compact filter this size there is certainly a balance between flow and filtration and it looks like Mazda chooses flow over filtration judging by the rather average micron rating of their filters. I was trying to improve on that with the Mobil 1.
 
Now I'm curious about what the micron rating is on all of these filters.
For specifications there’s no information on OEM oil filters. We can use Wix 57002 which is custom made for Mazda SkyActiv-G engines and the specs should be similar to OEM PE01-14-302A. Wix 51365 which is equivalent to Mazda older OEM oil filter B6Y1-14-302A mentioned in Mazda’s memo and the specs should be similar too. The comparison of these 2 Wix oil filters can be seen here:

Oil filter specs?

On nominal micron rating Wix 57002 is 15; and Wix 51365 is 21.

And here’s a long discussion on oil filters:

Bosch ST3300 Oil Filter - Fits 2016 but won't work for 2017??
 
Here are different oil filters listed for some Mazda vehicles:

OEM:
Mazda2 1.5L - B6Y1-14-302A
Mazda CX-5 2.5L - PE01-14-302A / 1WPE-14-302 / PE01-14-302A-MV
Mazda CX-9 / CX-5 2.5T - PY8W-14-302 / 1WPY-14-302

FRAM Ultra Synthetic:
Mazda2 1.5L - XG6607
Mazda CX-5 2.5L - XG6607
Mazda CX-9 / CX-5 2.5T - XG6607

Mobil 1 Extended Performance:
Mazda2 1.5L - M1-108 / M1-108A
Mazda CX-5 2.5L - M1-108 / M1-108A
Mazda CX-9 / CX-5 2.5T - M1-108 / M1-108A

Obviously both FRAM and Mobil 1 oil filters are one-size-fit-all while Mazda OEM oil filters have different specs for different engine requirements.
