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.
