I've used Blackstone for UOA on a race car for years, but now I want to do a UOA on my Ram Ecodiesel. My understanding is that I need to be aware of soot (ash?) levels in the UOA to judge when the oil is done. Blackstone doesn't seem to provide a # for soot in their analysis, so maybe I need to use a different lab?
Altho I can read a UOA it's kind of from a race car perspective so I'm really just looking at metals and dilution. I don't have any experience judging when an high mileage oil is "done" because race cars have frequent oil changes.
Guidance on reading a UOA for a low SAPS engine? I searched around but the threads re. reading a UOA are generic. Maybe that means there's nothing unique about reading a low SAPS UOA?
