OP, did you use any fuel system/injector cleaner during either OCI?
Yes I used one bottle of Royal Purple Max Atomizer fuel injector cleaner about 2500 miles ago which immediately caused a P0326 check engine light to turn off.
Interesting, on my most recent C&P I had the black residue similar to yours. This was the first I have had this from the Mazda and had theorized that perhaps it had to do with the Techron and Berryman I ran during the OCI.
I wonder if there is something to that
You can get the OEM filters in the $4-$5 range on fleabay, that's how I used to get mine, same filter for 3 consecutive Korean vehicles that I owned.
I may have a couple floating around the garage still, OP you are welcome to them, you pay shipping. My wife would be thrilled I actually got rid of something in the garage.
Have you owned the vehicle since new? If so what was the maintenance intervals.
Only made for and sold at Advance Auto stores. Basically, the same as the Fram Ultra with some "tweeks".i been gone for a while, what the heck is this new fram lol , i need do a search hehe

FRAM Titanium™ Oil Filter | 20,000 Miles of Protection | FRAM
FRAM Titanium™ is a high-flow synthetic oil filter engineered for protection up to 20,000 miles.www.fram.com
There seemed lots of sludge/carbon in the filter.No, I became the caretaker around 90,000 miles and prior to that the vehicle was very poorly maintained I would say to the point of being thoroughly abused.
