You have no idea as to the depths of my laziness and apathy. Hours can pass between the time I click "reply", subsequently get distracted by shiny things, cook dinner, watch some TV, argue a bit with the missus, and finally come back to the PC to find that I forgot to hit the "submit" button.
I consider this a superpower.

For the record I was never intending to use a fuel filter for my oil. I was curious if 2manyhobyz ((or anyone else) had any luck good or bad with the 551318. *EDIT I guess I did say I'd like to try the larger filter. I should have said A larger filter before digging into that 551318 filter specs as a sidenote*
I couldn't tell you. I would assume so since you have a picture of the filter I had posted installed? I was under the impression you had run that filter. EDIT I realize that a P551318 and napa 551318 (now 1318) are two very different filters.

When the new high pressure diesel injection (common rail or whatever terminology you prefer) arrived on the scene, the particulate size the filters allowed to pass was significantly less and new machines would stop working and the older ones would keep going. Most of my customers have lousy fuel handling practices and had problems with mechanical injection engines anyway.

I've used the Donaldson P551318...well for its intended purpose as a fuel filter. Never considered using it as an oil filter. It lists as a 9 micron filter per Donaldson's specs https://dynamic.donaldson.com/WebSto...63&item=742494
WIX lists it as 10 micron Wix 33403 & Napa 3403 Fuel Filter: FleetFilter Secure Store - Wix, Fram, Baldwin, Luberfiner
Filter Bags | Micron Size Comparison Chart | Clearstream Filters Inc. This is a handy reference chart for micron sizes.
My UWAG (uneducated wild *** guess) is that if a filter can catch particles down to 9 or 10 microns it would have a shorter service life vs a filter of the same size that can filter to 21 or even 40 microns. It would be interesting to see the particle count in the oil between 21 micron and 9 micron. My bet is there many more 9 micron particles and the larger 551318 filter might not have a much longer service life over the stock filter. The oil will stay much cleaner. I would love to do oil samples back to back with the same oil, change interval and driving conditions between a stock filter and the 551318. Then again I'm sure I will burn it off faster than anything to really matter.

Technically a manufacturer can advertise a filter as "10 micron" even if it only catches 10% of particles that size.

I've always just used the Purolator Pure One PL14459. It's the one specified for the B6t and BPt motors found in mazda 323 GTX's. slightly bigger than the non turbo version specified in the Miata.

With my sandwich plate and half cut intake manifold brace a larger filter is easily added to my setup. I did some research using WIX's nice customizable database and found a filter that would better match the larger aftermarket sandwich plate.
The WIX 51347 was the clear winner. NAPA calls it a 1347 in the Gold brand. It's huge compared to the OEM with almost twice the media area.

Bringing this thread back from the dead. I found that a 2024 Honda Accord filter (any engine) is about 1 inch longer than the Miata filter with the same bypass pressure. It is a good replacement if you want a longer filter element.

Increasing the bypass pressure is more important than capacity. Historically Honda specified a very low micron rating for their engines which is a move in the wrong direction for this application. It may actually offset any increase in flow rate from a larger element. For a high performance low service life application it would be desirable to have a high flow element in a sturdy canister with a reliable bypass design that is at a higher pressure.
