The flash point is low, and the insolubles are high with a low viscosity. I can take all of this into account when I split hairs with the delta between my VOA's of engine oil and the UOA's after some use.
The problem I have with this train of logic is twofold:
1. Blackstone has shown a history of recent OA FUBARS. We have no idea how "accurate" this list is.
2. OA's providing single-digit numbers are oft wrought with a lack of repeatability; you are sampling for something so minute, that running the same test on the same lubricant again will yield different results every time.
Essentially: Creating a baseline to factor into your oil analysis using these types of numbers may not necessarily be a good idea.
Now, the FP and visc factors I think would be useful for sure!
