The antithesis of the 500 and 600 miles per tank threads, this is the "How low can you go?" thread. The rules are simple; you MUST brim your tank as you would if you were going for the 500 or 600 mile targets, but then drive it like you stole it, spend your days stuck in traffic, or do loads of short trips to the shops. But the end result is "How few miles can you get out of your tank?"
So, how low can you go?
