Had a Blackstone oil analysis run on my 2015 JK after the most recent oil change (I went just under 5K on this one because I assumed it'd be colder than it is). Below is my analysis after 73.5k miles on the engine, & 4200 miles on the oil. I've had the cams, lifters and adjusters all replaced under warranty within the last 10k miles, so a lot of the top end is new save for the valves as well. Seems to be holding up well! Oil is Pennzoil Ultra Platinum 5W-30, interestingly enough came up under viscosity. Figured I'd share if anyone has a similar report they'd like to compare!
