As I understand it JetA1, diesel & paraffin are pretty much the same stuff & I know that a hot petrol engine will run on paraffin. Many years ago before 24hr opening a friend used to buy paraffin from a forecourt dispenser and run his Landrover on it when he couldn't get petrol. I have done the same with a lawnmower. The engine will only start if it is hot enough to vapourise the fuel. The Landy used to smell like a jet when it went by!!! I am not suggesting you try this in your aircraft!!
