Welcome to the forum. I own a 2012 that I ordered in June of 2012, and took delivery August of 2012. I have always put in Valvoline Premium Blue 15/40. The EVIC gives me a 'Oil Change Due' message when the on board computer says its time. I know the manual states change oil every 7,500 miles or when prompted by the EVIC. I change when the change oil message appears. It will vary from owner to owner depending on driving habits.
If you live in a cold climate, it is recommended to use 5/40 oil, IIRC. That is for when temps are at Zero degrees or lower. Makes it easier on the engine for cold starts. Any oil that meets specs is good. I stayed with the Valvoline Premium blue.
To reset the oil minder, turn the key to the 'on' position, do not start. Push the go pedal to the floor 3 times within 10 seconds, turn key off. When I have the change oil message, it will disappear when I have done the reset correctly.
From my owners manual:
Engine Oil Viscosity (SAE Grade)
Use SAE 15W-40 MOPAR or an equivalent engine oil
meeting Chrysler Material Standard MS-10902. Products
meeting Cummins CES 20081 may also be used. The
identification of these engine oils is typically located on
the back of the oil container.
In ambient temperatures below 0°F (-18°C), SAE 5W-40
synthetic engine oil that meets Chrysler Materials Standard
MS-10902 and the API CJ-4 engine oil category is
required.
I have a Fumoto oil valve in place of the drain plug. Works very well, and lots less mess when changing oil. Get a 93mm, 16 fluted cap to fit on the end of the oil filter for removal. I use a long 3/8 extension with ratchet to remove the filter. Make sure the old "O" ring comes off when changing the oil filter. I add a quart of new oil to the oil filter before installing it.

I use oil filter LF16035, and Fuel filter FS53000, both Fleetguard. Amazon has the better price on the FS53000 fuel filter tho. I order my oil & air filters from Genos in July, and get a years supply, when they have their 10% off sale.
