2015 Ram 3500 diesel has 4800 miles 7 months new. dealer said I need to do oil change now. 2nd dealer says not yet, when should I computer says 62 left
I did not make comments on my analysis on purpose. I wanted to see what others thought of the sample. My oil is AMZ/OIL 15-40 100 percent synthetic. I used the Fleetguard Stratapore filter. I think I was at least 8 mo on the oil. The oil is 10.4 TBN in the bottle.
I think I may just have a 15k personal service policy. Oil & filter, Air and fuel filters at every 15K. That's easy to remember.
