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.

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).
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.Mobil is a major, highly respected maker. I wonder why they haven't addressed this?
In addition to Hyundai、Kia、Infiniti、Nissan、Subaru, Mobil says the principle application of Mobil 1 M1-108A oil filter is also for Mazda (1990-08, 2011-16), and equivalent to Mazda OEM B6Y1-14-302; and Mazda issued a memo not to use B6Y1-14-302(A) on SkyActiv-G due to the reasons stated in there. The choice is yours.⋯ Are there really any other differences that would require the use of a Mazda filter.
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.
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.In addition to Hyundai、Kia、Infiniti、Nissan、Subaru, Mobil says the principle application of Mobil 1 M1-108A oil filter is also for Mazda (1990-08, 2011-16), and equivalent to Mazda OEM B6Y1-14-302; and Mazda issued a memo not to use B6Y1-14-302(A) on SkyActiv-G due to the reasons stated in there.

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:Now I'm curious about what the micron rating is on all of these filters.
