I would direct you to look at the flash point. That is one readily visible difference in the chemicals.
You looked up a generic kerosene with a COMPLETELY different CAS #. We already went over this, there are various grades of Kerosene just like there are various grades of gasoline. That does not make them more or less Kerosene!
If we are trying to be intellectually honesty here, compare the Comsol D-40 to one of the others I listed with the same CAS # like:

Take a look at this table from Citgo:
https://www.citgo.com/CITGOforYourBusiness/Petrochemicals/ProductInformationPetrochemicals.jsp
Look specifically for CAS # 64742-47-8. You will see there is a range of gravity and Distillation temperature as well as the number of differently named chemicals all wearing that same CAS #. There is a range of flash points from 44C to 79C. There is also some small variance in Paraffins and Cycloparaffins, however that appears to have no affect on flash point. The Flash point corresponds with the Distillation temperature.
You will also note they all have aromatics listed as
On the other hand, if we look up the CAS # of the product you linked to we find:

Quote:
Synonyms & Trade Names Fuel Oil No. 1, Range oil [Note: A refined petroleum solvent (predominantly C9-C16), which typically is 25% normal paraffins, 11% branched paraffins, 30% monocycloparaffins, 12% dicycloparaffins, 1% tricycloparaffins, 16% mononuclear aromatics & 5% dinuclear aromatics.]
You'll see that this CAS # has aromatics in it. It also has very different levels of paraffins and cycloparaffins making it a different product in the Kerosene family and these differences are why it has a different CAS #.
I'm not a tribologist, but you made my point for me. While Lucas may be mixing something with the same CAS#, and we can argue semantics all day, it is my opinion that it may well perform better than just randomly purchased kerosene due to some nuance about how it interacts with their formula. That was my point, anyway.
