Hi guys. I'm new to the Ram Ecodiesel world and trying to educate myself on my first ever diesel. I purchased a used, 2016 Ram 1500 Limited Ecodiesel. It has 12400 miles on it, so I'm a little apprehensive on how best to keep it performing well. I've always liked using fuel and oil additives to help keep things clean internally. So my question is, is it okay to use products like diesel extreme and seafoam in the fuel and oil? Thanks and look forward to hearing from anyone who can help. Thanks
