> Aircraft engines are designed to be light, and sacrifice low cost and the ability to burn cheap diesel fuel for that. Small correction: aircraft engines generally use kerosene-based fuels (Jet A-1, Jet B). Also cost-wise, aircraft-grade kerosene costs more relative to other uses of kerosene since those applications can tolerate kerosene of lower quality than aircraft-grade kero. https://en.wikipedia.org/wiki/Aviation_fuel https://en.wikipedia.org/wiki/Aviation_fuel
