I just watched a guy on youtube change the oil on his 2014 Ram Ecodiesel. The shocking part is he refilled it with Quaker State Ultimate Durability!!!! Am I right to be shocked? It doesnt meet warranty specs but the most shocking part is its a PCMO and its not going to handle soot very well. Well, thats the way Ive always understood it. Diesel oil in a gas engine is ok but not the other way around. If Im wrong please correct me. Hopefully Dnewton3 will chime in...
