Should I be concerned with some of the elevated metals? More so the iron? Also noticed Tin and Chromium this sample. Filter was AC/Delco P457G cartridge filter
This fill saw some pretty bitter temps this winter and a lot of snow lol
Mobil 0W-30 green cap in the sump right now...I'll change that out in 5K to see how we are doing and if metals come down at all
