Received my results from the Blackstone oil analysis.
- I changed my oil @ 1500 miles to Nissan Ester Oil.
- I switched to Redline 5w30 @ 5000 miles (a few days ago).
- The analysis is ran on the Nissan Ester Oil that was used between 1500-5000 miles on my Z.
- I will get another oil analysis done on the current Redline Oil after 3000 more miles.
(My 'note' included in my sample said that I'm on my 3rd fill of oil and that this sample was from my 2nd fill, with the 1st being factory, so ignore when they mention 3rd oil change.)
