I did cut open the 2nd filter, there was much smaller debris in it but didn't look fantastic to be honest, I can post pictures later.That's why, again, we dump first change early. Always have, but others don't agree.
I cut open the factory oil filter on our Mazda CX-5 at 2,300 miles. Super clean. I was expecting some tiny little things, but it was remarkably clean. Have had others that had a lot.
Cut open the next filter. Probably looks fine.
I do have a clean sample from the factory fill taken midstream that I could send off. Perhaps it would show very elevated levels of debris?
