Ive heard a few different opinions about putting JET fuel into the diesel truck. I work at an airport where i can get JET fuel for basically nothing instead of paying 3. 59 at the pump. Ive heard its ok on the engine and it wont do any damage and also that its not a good idea. I also heard if you do put JET fuel into the tank that you should mix it 10 : 1 with the actual diesel fuel. Any imput would be aprreciated.
