diesel, another    
  one of earth's forbidden  
    liquids (tied strongly to   
   earth due to being made of oil   
  (oil is the philosophers  
       stone, btw))     
 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.
