I was changing the oil on my 2016 F150 (3.5L, NA) and one site said M1-210 and another said M1-212 (please ... ignore the brand for now and focus on mechanical issues). Since both are supposed to be M22-1.5 threads, I figured either would screw on. But alas, the 212 starts about 1/4 of a turn then jams, while the 210 fits perfectly. Confused !!! Setting aside the base mounting width issue, shouldn't both have screwed on ??
Oil Filter Threads ...

Mobil1 filters are now made by Mann-Hummel , typically at factories that were formerly Purolator's to my knowledge, and over the past year or so there have been numerous complaints of Purolator and Motorcraft filters (also made at the same factories) with poorly machined threads that won't go on.
A M1-212 cross refs to a Fram XG10575 which is what Fram also lists as the correct filter for a 2016 FORD F-150 3.5L V6. I would have to believe the threads were messed up when it was made. The M1-210 cross refs to a Fram XG2. The threads for both are M22-1.5. The specs for the M1-210 are not very comparable to the the M1-212. I'm not sure I would be comfortable using it.
Am I positive? Well, since I don't have a "tap and die set" for that size, then no, but if you look up the specs for both, they are the same per published documents.
I am not asking or saying they are interchangeable, I'm asking "shouldn't each have been able to screw on?"

Yes; the threads "should" be the same, and therefore "should" be able to be threaded on at least with an easy start.
Assuming that all else is equal, there's three plausible explanations:
- the threads on the offending filter have a defect (burr; rolled or flattened thread lead; etc)
- the threads on the offending filter are incorrectly applied (wrong base plate on the M1-212 filter)
- the filter is properly made, but improperly labeled (It's not really an M1-212, but it got labeled as a M1-212)
It's not unheard of to have a filter with a manufacturing defect, regardless of brand.

I used to buy genuine Ford filters for my old MK1 Focus with the 1.6 Sigma engine. I nearly always found after 2 or 3 turns the filter would get tight, then 'click' and carry on like normal. I can only assume there was a bit of swarf or something that used to get stuck in the threads during manufacturing.
I started buying Mann Filters (part of the Mann & Hummel group) after that and they seemed to be of a higher quality and I never had that issue with the threads. I find Mann Filters to be of a very high quality overall. Seems you must get different filters in the US?
