Previous UOA here. 120167 miles on the engine at the time of sampling.
1 track day on this oil (NJMP, novice pace, street tires), near the end of the OCI. I had to top off with 1L shortly after that track day, so these numbers are probably mitigated slightly by that.
Tempted to blame the rise in Al on the track day. However, the number is still really low and no other potential wear indicators have changed. #ShrugLife
Big bump in fuel dilution!
In the pic, fuel dilution in a previous sample is blanked out because it turned out not to be reliable.
