From AvWeb:

This week at OSH, Maule debuted an M-9 fitted with SMA's SR 305-230
aerodiesel,
which was first certified in Europe a while ago and is now poised to make
inroads in the U.S.

I spoke with SMA (France) last week, at their tent at Oshkosh. They said
currently only Jet-A is certified. Diesel is not approved. Too many BTU's in
diesel, from what I understand. To many variations in diesel fuel. (Their
words)

Diamond Star's diesel burns Jet-A or regular diesel fuel and is certified as
such. Their engine is made by Thielert of Germany
