Picked up my new Ram 3500 yesterday and they informed me that I have to use mopar def fluid in order to not damage the system...have you other Ram owners experienced the same story?
If you have to use Mopar DEF to not damage the system thus keeping your warranty in effect, they have to provide it for free , read the Magnuson-Moss Warranty Act, ask Ford how their butt feels after it bit them on fuel filters
