   You are talking to a former airport fuel truck driver who actually   
   fueled aircraft on the apron.   
      
   I know the petroleum refining process. I am talking about adapting the   
   kerosene grade or gasoline grade of fuel to run properly in a diesel   
   truck engine. You just don't want to accept real life knowledge that you   
   don't know off.   
      
   Every competent person knows that you can increase the octane by adding   
   alcohol, and decrease the octane by adding motor oil. I am not talking   
   about what the refineries do in their distillation process.

   Our airport fuel trucks never left the airport property to get diesel   
   fuel from a gas station outside the airport perimeter. This is their   
   standard practice since the beginning of time. Do you think you'd know   
   better than me what aircraft fuel truck drivers use to fill their own   
   trucks' diesel fuel tanks?

   You should read properly before your expose. I am talking about   
   converting a very clean grade of kerosene (Jet A1) to use in a diesel   
   truck engine. If the Jet A1 is clean enough for aircraft, then it is   
   clean enough for a diesel truck. The trick is to add motor oil to lower   
   the octane to diesel fuel level.
