Maybe my fuel knowledge is old hat but IIRC, JP-4 and JP-5 are aviation fuels (what we put in our UH-1H aircraft).
I’m long since off flight status but in my ground unit we fuel our HUMMVs, trucks, HEMMTs and field stoves with nothing but JP-8 for years now. It initially caused problems as the solvent additives in JP-8 were flushing all the fuel tank rust particles into the fuel filters and clogging them.
Anyway, this massive fuel transfer to the IDF says things vis-a-vis Iran are ready to smoke, sooner rather than later JMHO.
IIRC they are currently using JP-8 for all aircraft and diesel. A special additive is used for diesel engines.
Using only one fuel simplifies supply.
