Oil report attached - just under 215k total miles on the truck (2006 6.0L) and 4700 miles on the oil. (Edit) Mobil Delvac 1 ESP 5W40 oil (not Mobil 1 TDT 5W40). Interestingly enough (no implication of value, just information sharing) - the viscosity was just below a 40 wt at that mileage (30 wt...

Does anyone have a virgin analysis on ashless TC-W3 oil?
