I prefer Kerosene. Diesel is supposed to yield a bit more power but it's real claim to fame is the price tag. It seems to me that it smokes a lot more, some engines require a change of settings in the ECU to run diesel. It also really stinks compared to Kero but it's not as stinky as Jet-A.
Without a doubt, kero will burn cleanest and smell up the car/shop/house less. Otherwise, I would ask Jet Central what their own recommendations are, as not all mfr’s have the same opinions and not even all engines from the same mfr are the same.
