I would be surprised if the dealer used Mobil 1 0-40 as it cost around 9.00 per qt ($25.00 for 5 qts at walmart ,,the crossfire takes just under 9 qts.
all those codes happen when you have low batt, clear them all and start over (dis connect batt for 5 min. open and close door 5 or 6 times to discharge all components can you record the knocking. does the ticking and or the knocking happen at idle? here is the throttle reset
