Primary advantage is fuel consumption - higher compression, lower pumping
losses (minor benifit for aircraft) and reduced heat loss due to the
stratified nature of the combustion all help to improve efficiency.
Increased fuel density also gives a boost to "miles per gallon" - but for
aircraft it's about "miles per pound".

Oh, I forgot, they can run on Jet fuel if the injector pump will tolerate
it...

AFAIK, the newly demanded ultra low sulphur diesel fuel is nasty stuff for
the pumps, because the hurriedly implemented refining process also strips
lubricants from the fuel. I have no idea whether this will be a continuing
problem or whether other processes maintain the lubricity of the fuel.


On the downside, diesel fuel is good for growing algae, dunno about jet
fuel - but given the number of hanger queens at the typical airport, I
assume we will find out when diesels make a dent in the aircraft market.


I don't know about the kerosene based jet fuel sold here in the U.S., but
some of the foreign stuff is (or at least was) a feeding ground for
micro-organisms. The Eastern Airlines L-1011 that went down in the Florida
Everglades some years ago was apparently full of the stuff after having been
previously refuelled in Israel.

BTW, I'm glad someone remembers what a hangar queen is. ;-))
