Sending mine off today.
2017 GTS. now at 3300 miles. Oil was filled with full synthetic Liquimoly Molygen 5w-50 and a K&N filter when we purchased with 1300 miles (by Zen Racing, Atlanta..if you're on FB you may be familiar with that ordeal) . It was way darker than expected for only 2000 miles, but it now has Mobil 1 0w-40 and the OEM Mopar oil filter.
I'll update as results come in.
