I was told that my 2014 v6 jeep limited came with 4 free oil changes in two years and I only need to change oil every 6 months or indicated by the computer on my jeep. Does anybody know what kind of oil they use? I was wondering if the dealership use fully synthetic oil or just blend oil? In my case, I guess it's probably not synthetic oil I guess. If it's not fully synthetic, don't we need to change the oil every 3000 miles or 3 months? That's what some mechanic shops told me.
Does the dealership use fully synthetic oil?

Yea, that's what I was thinking. I'd better do it myself. Mobile 1 5w-20 should be okay. But is the extended performance 5w-20 better? Also, does mobile 1 has the right filter for 3.6L v6? Or I can only buy the filter from my dealer?

Well, ain't this a can o worms 
Based on the boxes I see at my local dealers, they use Penzoil conventional and synthetic oil. Your Jeep likely did not come with syn from the factory. Conventional oil can easily go 5, 7, or even 10,000 miles on todays engines.

3,000 mile oil changes are a thing of the past. Just throwing away money if you are performing it that early on a new vehicle. Stick to the 6 months or when the computer tells you to change the oil and you will be fine.

Standard oil changes are dino or semi-synthetic, depending on the dealer. But you can upgrade to full synthetic. I run full synthetic in my MY12 Summit...in fact, I'm due for my 24K change as of about 8:30p last night when it ticked over and the little chime rang.

Except for the SRT, they are factory filled with dino oil meeting Chrylser's specs. Based on the price difference between dino and synthetic, I would be very surprised if a dealer's "free" oil changes were with synthetic, especially when the owner's manual does not specify it.
We (at the factory) only use synthetic in the SRTs and diesels.
Yes, dino/conventional oil CAN last 10,000 miles in today's engines.
Just check and fill up to normal if needed.

I read it twice but it doesn't say whether it's synthetic or not. It does say change it every 6k miles or 6 months. My last car is a very old car and usually change the oil every 3k miles or 3 months. So it surprised me at first the conventional oil now can last 6 months.
That works for me.
BTW - trade your Sharpie for a paint pen. The tag on my RR control arm is fading. I'm having the dealer ship the Jeep back to JNAP, under warranty of course.

I guess I will ask them how much extra I need to pay if I want to go with the synthetic. If that's over the price of synthetic oil from walmart, then I will bring my own oil so that they can save some oil and I can save a filter and my own labor.
That was a paint pen.That works for me.

It's interesting to me that the manual calls for oil changes every 6,000 miles, but the maintenance minder seems to last to 10K every time... So I'm wondering if somebody just goes by the maintenance minder (and only changes the oil every 10K, even with synthetic) whether they'd potentially run into warranty coverage issues.

My ‘14 manual doesn’t call for 6,000 mile oil changes, just to go by the indicator which can activate as early as 3,500 miles or up to 10K unless under severe duty conditions which are earlier. Going by the minder and using a FCA approved synthetic (which is what I do) should never cause a warranty issue.
Where do you see 6,000? From what I can see the manual says to follow the oil change indicator system.
Scheduled Servicing — Gasoline Engine
Your vehicle is equipped with an automatic oil change indicator system. The oil change indicator system will remind you that it is time to take your vehicle in for scheduled maintenance.
Based on engine operation conditions, the oil change indicator message will illuminate. This means that service is required for your vehicle. Operating conditions such as frequent short-trips, trailer tow, extremely hot or cold ambient temperatures, and E85 fuel usage will influence when the “Oil Change Required” message is displayed. Severe operating conditions can cause the change oil message to illuminate as early as 3,500 miles (5,600 km) since last reset. Have your vehicle serviced as soon as possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator message after completing the scheduled oil change.
NOTE: Under no circumstances should oil change intervals exceed 10,000 miles (16,000 km), twelve months or 350 hours of engine run time, whichever comes first. The 350 hours of engine run or idle time is generally only a concern for fleet customers.
Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) or 350 hours of engine run time if the vehicle is operated in a dusty and off-road environment, or is operated predominantly at idle or only very low engine RPM’s. This type of vehicle use is considered Severe Duty.
