So i just received my latest analysis, with 6k miles on this particular change. I used the M1-108 filter on this run. According to Blackstone everything is normal and where they should be. TBN was at 3.2, they thought i could probably run it for a couple thousand more miles and actually recommend it for the next change.

This was with a track day included, at 100+ degree weather.

 

Nice info!
