Maybe all this cetane boost stuff has been a bit of red herring. Useful in our fuels perhaps but not the be all that was thought. After all, high cetane numbers or index is preferable but if you can't create a high enough temperature to cause ignition and get the fuel atomized then it just isn't going to go pop.
Yes, I think the same. I wrote something about it a few pages back. I have some octane booster to try next time I get a chance. Fuel chemistry is a complex matter. I can't pretend to know much about it. The fuel mixing is trial and error, but I do research what might work and what won't.
Trimethylbenzene is naturally occuring in crude oil. It's nasty stuff. Not much information regarding engines though.
