On our test benches both US and in Taiwan, Diesel yielded up to 5% higher thrust, while up to 10% less in consumption.
If you mustn't use Diesel, please consider Kero rather than Jet A. Dirk, Vera and myself don't tolerate the stench of Jet A well. Also, make sure you do not use contaminated Jet A from fuel dumps, many engine running problems corrected by switching to Diesel, Kero or pump Jet A.
