Since Dodge SRT has a technical partnership with Pennzoil/Shell (similar to Ferrari,) that's where I'd be looking. Their GTL based products (PUP/PP/SHU) are fantastic (I use them in my Sludge prone Saab 9-5 among others.)
Choose the correct grade PP 5W-20 meets MS-6395 the and make sure that it meets he correct Chrysler specification for warranty purposes. If you local auto-parts store doesn't stock a particular product, Amazon will or your local shop should be able to order it in. If they can't (or wont) then your money is probably not good enough for them, and you should take your business elsewhere.
Below is a chart of all Pennzoil products and the specs they meet:
