Got my analysis back from Blackstone on this oil last oil change. Wasn't watching my odometer well and went 4000 miles on it with 1QT makeup. Iron was @ 75 where they say it should be around 35.

I'm about to send my next sample at 3000 this weekend (held on to the last oil for a while). We'll see what the numbers are now.

How worried should I be?
