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.
