Kind of a weekend/vacation/bad weather vehicle, 4.5 years old with 20k on it. I changed thefactory fill at 2000 miles, then it's been a change every year with whatever synthetic is on sale. Usually ends up being 4-5k on an oci.Lots of these Jeeps burn oil, not mine. This run saw a lot of summertime idling on the trails.
'10 Jeep Wrangler
Miles on Unit 20,500
Miles on oil 6,000
Pennzoil Ultra 5w-30
Bosch Distance Oil Filter
6 qt sump
No make-up oil added, still full on the dipstick.

Thanks for the notes. It sounds like you're taking pretty good care of this engine, and these results
don't point to any major issues. We did find some high copper and silicon, but those could still be residual
from wear-in. When the engine is new, it leaves a lot of excess copper in the oil, from brass/bronze parts
wearing in, and silicon, from sealers. Normally, we expect that to be gone by the third or fourth oil change,
but sometimes it lingers a little longer. These should improve next time. The TBN is good at 3.9, but try
another 6,000-mile oil run to monitor.
