Greg,
happy to have you on bord! Also I found a mess of charcoal starters. Your msds is rather short, but they say isoparaffins (isoalkanes), rather low C number. It seems to be about 2 C less than "light" kerosene. This means (should mean) a significantly higher evaporation rate, that is worth trying. Furthermore, this has no aromatics, the worse diesel fuel, so this should compensate the somewhat lower cetane of lower C components.
I don't rely solely on cetane number, since from that point of view only, margarine should be the best fuel!
I suggest to increase , say by one third ,the cetane booster you usually use. I have found an interesting vast official source of petroleum distillates, with respective cas numbers. It comes from European Community,but my copy is in italian, so I am searching an english version for here.
Ugo.
