Depends where they get their gas. When I was doing speed I carried around an electric siphon. I'd go to a movie theater after it got dark and wait for someone in a mid-size to full sized car, truck or SUV park their car and go in for a movie then fill my tank up. I also used to get various car parts for my car or to sell that way. You are guaranteed that the person who owns the car will be gone at least an hour as long as they didn't have any small kids with them. Sometimes those fuckers would come back right away because the kid was mis-behaving or got sick. Oh the memories...
