Synthetic Oil
Who's running synthetics? I've always used Mobil 1 or Royal Purple. I plan to switch at the first scheduled oil change.

I switched out the OEM oil at ~1000 miles to Pennzoil Ultra 5W-30. I then switched to Mobil 1 Advanced Fuel Economy 0W-30 for the winter. Will switch back to Pennzoil Ultra 5W-30 in the spring.

Re: Synthetic Oil
Im a big fan of synthetics. Have ran synths in every car since my 1990 Nissan 300ZX turbo.

Going to do a oil/filter swap at ~1000miles, and refill with regular dino oil. (Some may call this old school or overkill, but hey, its my ride and you can never go wrong changing your oil too often!)
At first scheduled change at 8k miles I'll switch over to synthetic.

Re: Synthetic Oil
I'm running Mobil 1 and like it alot. The 5.7 seems to run a little smoother after the switch but perhaps it's just in my head.

Quakerstate Ultimate Durability for me always works awesome for me, And the dealer does it :)

Changed the factory oil at 4000 and use either Vavoline 5W20 or Mobil 1 5W20. Change every 5000 miles.;)

Re: Synthetic Oil
What brand of oil does chrysler use if you tell the dealer to put in full synthetic?

Believe it depends on the shop, but I've seen Pennzoil Platinum at a few shops.

Mobile 1, getting from Costco if on coupon. 5K miles does well on any car besides my MB that need exotic oil :)

Re: Synthetic Oil
The 8000 mile oil change interval in our manuals is based on conventional oil. Now with that in mind, I buy whatever major brand synthetic oil that is on sale at the time (ie Mobil 1, Valvoline, Pennzoil, Quaker, Castrol) and follow the 8000 mile intervals except for the first oil change at 3000 miles.

If 8000 is good enough using conventional, I know I have even more safety margin with synthetics at that 8000 interval. No need to over-do it, by changing it even earlier. I mean Audi's, BMW's, MB with turbo engines have 10-15K mile intervals, and they have been doing that for a while now.

Not a new concept...
