More fuel means higher mass, thus less temperature swings due to ambient
conditions outside the tank, thus less formation of condensation of moisture
from the humidity in the air.
If the tank is full, there is less room for air, and since air is the source
of condensation on the bare metal inside the tank, more fuel means less
supply of moisture for condensation.
If the tank is full, there is less metal exposed to air inside the tank, so
more fuel means less rust and contamination of the gas during storage.
More air means more oxygen touching the surface of the fuel, thus more
oxidation, which means more deterioration of the fuel, ultimately meaning
more vinegar and muck, and less gasoline.
So, what's to argue about?
