Way back when I lived in Alaska - in the 1980's my cousin lived in
Anchorage and worked for Shell Oil. He told - and showed me - that all
the Gasoline sold in Anchorage and the surrounding area came from a
single cracking plant - the Tesoro plant down on the Kenai Peninsula
some 110 miles away in a straight line. The fuel was pumped through a
pipeline to a distribution point on a tank farm in Anchorage, and then
distributed to the various Brand Name oil companies. That fuel was all
the same - no matter the name of the oil company - Tesoro, Shell, Gulf,
Exxon, Mapco - all got the same fuel. The difference was in the
additives added by each oil company to the fuel to make it their
own.Diesel, High Test, Low Test, Aviation Fuel - all was pumped through
that pipeline to Anchorage for distribution. After each fuel delivery of
a particular type - the pipe was purged with air, then purged with a
wash of the next fuel type. This wash was considered waste fuel as it
would be a mix with what comae before and was about 150-200 gallons..
Legally, it could not be used, since it was not pure. Aviation fuels -
100 Octane, and 80-87 octane - were pumped in succession, but the fuels
when mixed were considered not saleble - but my airplane would run on
either fuel or a blend of both - so instead of the fuel being wasted -
my cuz would barrel  up the 100/80/87 mix and we would go on a fly-in
fishing trip.
