Have begun researching how I should interpret oxidation and soot levels in a UOA. Haven't had it done yet but I will next fall after extending my OCI out to 2 years on some of my diesel equipment. I think those will be very useful stats in this case, alonside the regular stuff, in determining if I am pushing the envelope too far. Don't think so, obviously, but there are lots of variables and I wanna know for sure.
Not sure yet what I "know" on this topic so I'd just like to open it up to anyone with helpful comments, information or good study resources. I'm most interested in safe vs unsafe levels in both those areas. Also interested in the tests themselves and if accuracy can be a big issue for an "average" lab.
