JonB set me straight on exactly the same point. The rings will seat just fine. If the dealer put Mobil One in the car then that's great. My feelings on it is why use Mobil One on the first fill? Chrysler wants us to change the oil WITH-IN 200 miles. Do follow the break in procedure closely.

Discussion: The following break-in procedure is suggested for any New Viper Engine.
Share this information with you customers as needed.
During the first 1000 miles (1610 km):
1. Avoid long periods of engine idling.
2. Wait until the engine has reached operating temperature before driving
enthusiastically.
3. Check the engine oil level at each fuel fill since a new engine may consume some oil
during the first few thousand miles (this is normal and not a sign of an engine problem).
4. Keep the vehicle speed below 70 mph (113 km/h).
5. Do not make any full throttle starts or full throttle accelerations.
6. Avoid driving at a constant engine rpm for long periods as follows:
. First 200 miles interval (322 km), light throttle run-ups shifting at a maximum of 2500
rpm.
. In addition, it is suggested to change the engine oil within the first 200 miles of engine
break-in.
. Second 200 miles interval (322 km), light throttle run-ups shifting at a maximum of
3500 rpm.
. Third 200 miles interval (322 km), light throttle run-ups shifting at a maximum of
4000 rpm.
. Fourth 200 miles interval (322 km), light throttle run-ups shifting at a maximum of
4500 rpm.
. Fifth 200 miles interval (322 km), light throttle run-ups shifting at a maximum of 5000
rpm.
