What makes gas so much cheaper in some places? Is it old gas or
something?

There are many factors. Aviation gas has to be trucked all the way from the
point at which tetraethyl lead is added to the gas. The further the airport is
from there, the higher the cost will be. Major airports charge a premium simply
because space there costs more. Airports which are owned by municipalities
sometimes add taxes and fees. Some States add taxes. These are the major reasons
for regional price differences.

Within a region, there are also various business practices involved. Some FBOs
track wholesale fuel prices and raise or lower their prices accordingly, much
the way auto gas stations do. The majority, however, set their prices based on
the cost of the last load of gas they bought. If they bought that gas cheaply,
the price at that FBO will be relatively low until they sell it all. If it cost
them a lot, they'll have high prices until they sell it all. As far as pilots
are concerned, if the price of auto gas went up recently, the cheaper fuel is
likely to be older. The reverse is true if gas prices went down a few weeks ago.
This is especially true of FBOs with relatively large storage tanks.
