UOA Jeep 3.0L CRD 3000 miles

Just got my 2K and 3K sample report. TBN is dropping, but will probably stabilize. Calcium going up? Soot went up at 1K then dropped a little at 2K (during long hot road trip). Phosphorus going down. Less than 200 miles to go until the 4K mark!

Just sent off a sample taken at 4006 miles of the Mobil 1 ESP Formula M 5W-30. That means an update in a couple of weeks. This stuff is blacker than a night of the dark of the moon at the bottom of a Virginia coal mine!
