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.
