Spills and gases are not even close to being on their agenda here, they just want to curb vandalism by denying them easy access to gas, for someone who really wants petrol for purposes other than as fuel in vehicles, it isn't that difficult to siphon some out of gas tanks of vehicles. That's how I did it, otherwise I wouldn't ever get to drive that vehicle again. How do you keep a can in car, if they don't sell it in cans, how do get oil in cans?
