I changed my oil after 3 month and about 800 miles and I noticed what looked like very fine pieces of metal swirling around in it. 06 coupe has 6500 miles with Mobil 1 0-40w. I also noticed contamination on my last change. Is this normal on the V10? My local Dodge dealer does not send oil samples out and said it needs to break before anything can be covered under warranty. I would like to know what is going on inside.
