@GunsOfNaverone, Kero and JetA1 are very similar, as is diesel fuel and can be used almost interchangeably, the big difference is JetA1 has additives to reduce the chance of explosion in a crash and to keep it from freezing at 35,000 feet where it is -65°F pretty much year round. JetA1 Stinks real bad compaired to Kero, and the stink con not be gotten out of fabric, so once spilled you will know it forever. Diesel also stinks real bad and is a very dirty fuel That is why diesel engines have the massively huge fuel filters. Diesel also burns a bit hotter than the other 2. That is why I run Kero in all of my jet engines, the others are to stinky.
