I would ideally like to do 10k intervals with a filter change every 5k but I guess the oil analysis will tell me what I can do.
I was planning on using an inexpensive synthetic for my first change at 1k since it will only be used for 3k miles, and then move on to a more expensive oil for the 6k intervals.
I was thinking Mobil 1 for first change since its cheap at Autozone, and then switch over to something else.
So my friendly oil analyzers and scientists, what do you recommend for me?
Everything you need to know is right in your owner's manual as far as oil weight, ratings, and oil change intervals. That is where you should start with a new vehicle with warranty to protect. Find out what the mfg requires and then decide from there between the avaiilable oils that meet those requirements.

Owner's Manual Page 575-576
Your vehicle has an OLM. You can go by it if you choose. However you also have a maximum time/mileage limit that applies if the OLM does not trip by that max limit. The max limit for your vehicle is 1 year OR 10,000 miles( whichever comes 1st ). So you are fine with your 1 year 10K OCI plan. Chrysler allows for that OCI in writing. Just remember if you reach 10K before a year, or reach a year before 10K, you have to change the oil anwyay.
Your vehicle manual calls for a 5W20 oil, w/ the API Starburst, and that meets/exceds Chrysler MS6395. If you can not find a 5W20 that meets/exceeds MS 6395 the manual says you can use a 5W30 that meets/exceeds Fiat 9.55535-S1 or Fiat 9.55535-S3. You shouldn't have any problem finding a 5W20 that carries the API Starburst and that meets/exceeds Chrysler MS-6395 however.
You do NOT have to use an oil that is officially certified to MS-6395. Just that meets/exceeds it. Someone mentioned Mobil 1 earlier. While it is no longer officially certified you can rest assured it meets or exceeds all performance requirements and is fine to use if you wish to. The hold up is not money as another member said it is because Chrysler added a ridiculous multi-year test requirement to the certification process which delays the ability to get certified. Mobil 1 would be a perfectly fine choice.
I personally would run synthetic if you plan to go a year and 10K. IMO that is pushing even the best conventional oil too far. You say you like Amsoil and if so they have an oil that meets all of your needs and warranty requirements and that can go 1 year/10K with ease. That is Amsoil XL. XL is API certified w/ Starburst, is available in 5W20, and meets/exceeds Chrysler MS-6395. They also have Amsoil OE that also meets all of your needs/requirements but 10K might be pushing it's service life. For like $1 more a qt go with the XL.
Other options for you to consider that are available in 5W20, carry the API Starburst, and meet/exceed Chrysler MS-6395 would be...
Royal Purple( API Licensed formula )
Kendall GT-1 w/ Liquid Titanium
Pennzoil Platinum
Pennzoil Ultra
Quaker State Ultimate Durability
On a 1 year/10K OCI I would use a premium filter like RP, Amsoil, Mobil 1, K&N, Purolator Synthetic or PureOne, Bosch D+, etc...
Seeing as you asked for our opinion as well I will give mine. Below is my thoughts on oils to use in order...
RP API 5W20
Kendall GT-1 w/ Liquid Titanium
Amsoil XL 5W20( if you wish to use Amsoil )
I would use the RP filter as my 1st choice. If I couldn't get an RP filter( think the new 3.6L uses a cartridge filter that has limited options right now )I would use one of the following = Mobil 1, Purloator Synthetic, or Bosch D+, or Purolator PureOne.
