Congrats on owning a Wrangler!
JK Tech Forum - Jeep Wrangler Forum
^^^Here is a Forum to discuss your engine oil usage.
First, the 3.6 engines are known and proven as being very dry engines. Normally at a 5000 mile oil change interval, it should show full, or close to it at the top of the Hash marks on the dipstick.
I also have two (2) Wranglers with 3.6 engines in my Family, and they both DO NOT SHOW ANY NEED..to add oil between changes..FYI
1. Are you using the correct viscosity engine oil 5w20, or 5w30?j
2. How often are you changing the oil and Filter?
3. Look for exterior oil leaks.
4. Remove you air induction system, and see if there is any silicon (dirt) entering your throttle plates. If yes, you may have a dusted engine.
^^^The above is a good place to start looking at.
