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.
