How dark was your oil before you changed it?

Mobil 1 is definitely dark amber in color. My Crossfire oil does not darken much between oil changes. It's definitely not going to come out of the bottle clear.

I don't know of any recent formula changes, but Mobil has changed the forumula over time.

The dealer should be resetting your FSS using the instructions found in the owner's manual. I would expect any Chrysler dealership to get this right. I could tolerate a non-dealer affiliated shop not knowing how to do it, but I would be disappointed in a dealership that doesn't do it. Anyway, it's easy to do yourself.

What bizarre time? Bizarre as in incorrect, or bizarre as in 25:15?

I think some of the confusion over "change" in formula is the result of whatever the shop is selling at the moment. Chances are maybe the dealer is changing from 5W-40 to 0W-40. Mobil 1 ESP Formula M 5W-40 should be fine for your engine as well.
