Sassless is saying yes..... but with precautions, some of the new hightech diesels in light trucks etc only use jet fuel in an emergency and ensure diesel oil is added for lubrication of the fuel pump (jet fuel is a dry fuel). In your old Landcruiser ,F100 diesel, power cart etc, get a clean 44 gal drum add 5 to 10 litres of diesel oil (the same stuff you put in the engine!!) and fill with your aquired jet fuel and use in the cruiser to your hearts content, jet fuel smokes a bit more than diesel and is down a bit on power but if your getting it for nothing/cheap who cares!
