I have done my own & use synthetic oil since day one if you are concerned use the Mopar filter-keep the receipt & write the day & mileage on it that you change it what can they say?
I have 62000klms on mine & the dealer told me that I did not even have to bring it in for a check up as there is only oil & filter & air filter to maintain as there is no fuel filter & the tranny is supposedly sealed even though I got the dealer to change my oil & filter @ the one year mark
My 2 cents
