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.
