Treven, the idea came from the evaporation and lubrication discussion we had. I'm not sre if it was this thread or not. The idea is the charcoal lighter has a narrow boiling range that is lower than that of kerosene. This might lead to more of the fuel component evaporating, for better lubrication and reduced fuel consumption.

I think that cetane rating isn't everything. We can change it as we need with cetane booster. I added 2-3 times what I normally use by mistake once and it certainly advanced ignition timing to the point I couldn't use the mix.

Some of the other MSDS I looked at said the lighter fluid was Stoddard solvent. There are only a few available here. I'll have to look around at stores to see what else I can get.
