Blackstone comments:
These are some nice results! Even though you ran this oil a good deal longer than the last, there's hardly any more wear to show for it. The 3.6L Pentastar powering your Jeep looks like it had no problem with the additional miles, and the oil itself held up well, too. Its viscosity is still in grade, no contamination was found, and the TBN is a strong 3.5 (1.0 is too low). The air and oil filters did a good job, too, based on the normal levels of silicon and insolubles. This all adds up to an ideal report, so feel free to run the next oil even longer. Check back after ~9,500 miles.
