I know that there are many, many theories out there on this. Myself? I was always afraid of used motor oil. Maybe my fear was unfounded. This was an interesting read. According to this medical study, new motor oil and used motor oil out of a diesel engine was found to be less carcinogenic than used motor oil out of a gas engine.
I also was at a talk at work some months ago (I work for a company that makes chemical analysis equip); where a person studying carcinogenic compounds from oil drilling found that where the oil comes from is a big determinant in whether the crude oil has "BTEX" (Benzene, Toluene, Ethylbenzene, Xylene) in it. i.e. Canadian Tar Sands oil is much worse than Texas crude.
We're all going to die from something, so I'm not going to debate whether someone uses old motor oil, it's America...but there is at least one data point that says that some oil is safer to use than others.
