I wonder if it's the local (State) fuel taxes that create the wide range of fuel pricing?
One of the things I've recently heard regarding the fairly dramatic drop in fuel costs is that the Oil Companys are a bit worried about all the talk of alternative fuel use, more economical vehicles and people just not driving as much. They're concerned that they may be cutting their own throats with the high pricing & that we may do something about it.
The other thing is that we have not had any damaging hurricanes impacting oil producing & refining areas of the country.
Last winter was not that cold & did not use up as much home heating oil.
Also, there have been some recent, new, crude oil finds.
