Here is a link to my first post last year when I noticed increased Iron and Aluminum for the first time since starting to get UOAs on our 2016 Mazda CX-5 with the 2.5L naturally aspirated Skyactiv motor: https://bobistheoilguy.com/forums/t...2k-mi-2016-mazda-cx-5-2-5l-n-a-77k-mi.390472/
The car always showed really low wear metals until the previous UOA. I decided to stick with the same OEM Mazda Moly 0w-20 and OEM filter (this time moved from the one made in Thailand to the Tokyo Roki version made in Japan, but otherwise same combo) to see if it was an anomaly and again, the wear metals came back high, Aluminum even higher than before! Since I was worried, in addition to the BlackStone reports I've been getting for years, I also sent another sample into WearCheck (both are posted below). Can anyone smarter than me weigh in on these reports and let me know what yah think? For reference, and maybe I'm grabbing at straws here, the last two oil changes with the elevated wear metals were from the same case of Mazda Moly oil I bought from a Mazda dealer on Amazon that I sat on for a good three years or more (not that age has anything to do with it, but could it be a "bad" batch?)...like I mentioned, maybe I'm grabbing at straws.
For reference, this change (before seeing these) I went ahead and moved over to HPL Premium Passenger Car Oil in a 0w-20 vintage with another OEM Tokyo Roki filter. Hopefully that one trends back to the original baseline(s) as far as wear metals.
Thanks!
