The biggest difference between standard mogas and avgas would be that avgas
is actually manufactured to a tighter Mil spec than the petroleum industry
standard for mogas. It's also handled in ways to minimize contamination.
Mogas can be transported in the same pipline or truck directly after a load
of diesel or other fuel without any cleaning procedure. Mogas and diesel
fuel can be co-mingled in the same truck, in separate compartments. Avgas
must be handled and hauled alone. Avgas can only follow mogas or after
cleaning procedures. Same for Jet A, Jet A can follow a Kerosene shipment,
but not a diesel fuel or gasoline shipment.

They do the same here. The truck's tanks have to be flushed
with 100LL before they can fill them with it and the batch is tested
and a detailed printout sent with the load. The liability for Avgas is
huge compared to Mogas, and the refinery and trucking outfit have to
carry more insurance for that, too. There are many ways we pay for our
litigious society.
