Hello, this is my first post here been a lurker for too long! This UOA is on my 2017 Ram with a 6.7. I noticed the oil looked watered down. The oil was Rotella T6 5W40. The Oil and filter was changed to T6 15W40. 50%of the usage was towing a 5th wheel trailer. I normally change the oil every 7k. I am hoping the iron content goes down.
