Pay more and Use more
Airfoilmod, if the fuel is dispensed by volume rather than weight you will pay more per pound if the fuel is hot and, yes, you will burn more in volume for a given output in thrust or HP. Turbine engines are more reliable than piston engines, you have only to look at relative TBO's to see that. Don't run your PT-6 for any longer on gasoline than you have to either. Apart from unwanted deposits on the turbine, if memory serves me correctly your range is reduced.
