Our crop dusters are certified to use jet a, kerosene, or diesel. Kerosene works great and has a lower sulfur content than jet a to keep toxic fumes to a minimum when using in homes for heat. It is usually very clean like jet a but is not strictly monitored because it's not intended for air craft use. Diesel is a great fuel on one hand because you get more BTU's per gallon which equates to more power. The down side is it's filthy dirty. Here in Louisiana our diesel comes on barge up the Mississippi river and it's terrible. I don't know about other parts of the world but we only use it when all other sources have been exhausted.
My biggest concern using diesel is all the foreign matter that tends to clog filters and fuel nozzles if it were to get past the filters. Just my $.02 worth.
