I don't think 5w20 is on the approved list. Stock up on 0W40 when it is on sale and buy a good fleece filter from your local auto parts store. I don't take my Crossfires to the Chrysler/Dodge dealerships as they barely have an idea of what a Crossfire is. If you have 5w20 in there now, I'd highly recommend replacing the oil ASAP.
