Check your owners manual, I believe it will say no longer than 10,000 miles, or 1 year. Also, your car will have an Oil Life Monitor that will tell you when to change your oil based on how you drive, which will probably trigger around 7,000 miles (assuming average driving conditions.)
As mentioned above, I believe Chrysler caps the recommended mileage at 10,000 or when the OLM trips. I have two 3.6s and I believe both would go about 9,600 miles before the reminder would light up. Most I've gone is 8,500 with a synthetic. The pentastar is easy on oil.
With full synthetic, you should be fine changing it at 10k unless you do all short trips and it takes you many years to get there. Just keep it topped off.
The OLM knows better, than most, and is conservative. My aunt went to minus numbers in her honda, before she knew why that number kept running for years, kkk. Some people never opens the owners manual, because is too complicated... I'd Do one 10k with a UOA.
Is that the minivan? Those rarely see over 3000 rpm. My Toyota specs 10,000 on 0W-20. My other 6s and 8s OLM at 8000+ so I'd start with synthetic to 8000 and test if you want to go farther.

I do UOA through Polaris labs running full synthetic. They don't even ask for a sample until 7500 on the oil; then send in a sample. Even if you don't plan to do UOA on a continuing basis, I would call it intelligent maintenance to use lab analysis to set precedent and determine your oil change interval.
