diesel, another    
  one of earth's forbidden  
    liquids (tied strongly to   
   earth due to being made of oil   
                                
  (oil is the philosophers  
       stone, btw)      
                                  
                             ibis 
 so it's a                        
 fuel, right?                     
 we can run  generators and robot canines 
 and  stuff on  this  shit. hard to  find 
 due  to  half-assed  "attempts" to  stop 
 global warming,  but easy to steal  once 
 found -  you  don't even  have  to  hack 
 anything (might have to taste it though) 
                                          
 best  to  search   at   night,  roadside 
 trucks  and lorries are already emptied. 
 hidden vehicle  graveyards  out  in  the 
 desert perhaps,  if the  dragons  didn't 
 get  to   them  first.  people's  yards, 
 fenced   in.   those   towns  were  some 
 company   owned    (and    fenced   off, 
 important!)  entire parts of it...  they 
 would usually have a fleet of  vehicles.
