Thanks for all the suggestions.
it will go to dealer....
Mama is not happy

Before heading to dealer get seafoam or startron engine treatment & add to tank.

Have you checked the oil level since the 3000 mile service?

Seems like someone mentioned that the fill quantity had been modified to a lower amount. I thought the reason was that the performance might suffer if the oil level got up to where the crank would be thrashing it around. Surely the dealer didn't put all six quarts in that come in a packaged oil change kit.

I've drained about 12 ounces from the original dealer prepped level that our 2015 base RT was delivered with.
The oil level was above the top "bulb" on the dipstick and hard to see.
When I do my first change I'll stick to the 5 qt recommendation for the SE6.
