I would be comparing this space age Diesel mix against a standard kerosene-containing fuel and compare the tractability and overall ease of operation and most of all comparing power between the two fuels. For me, the fuel has to tune well, throttle well, perform equal to or better than commercial blends and the engine has to be easy to start. Also remember that throttled variable compression Diesels have slightly different needs than fixed throttle and fixed compression Diesels.
