A reader comment on my previous post about our willingness to pay for name-brand gas caused me to delve a little deeper into the gasoline chain of custody. If you're a BP or Shell or Marathon devotee, you might want to consider the journey from well to your neighborhood station-
The oil is pumped from the ground in Alaska, Canada, Mexico, Venezuela or wherever.
It is transported via tanker or pipeline to refineries, primarily along the U.S. coastline, (including Louisiana, as we found out post-Katrina) where it is cracked into components, including gasoline.
From the refinery, this gasoline flows through the pipeline network that criss-crossing the country, eventually filling tank farms in our metropolitan areas.
At this point, all of the gasoline is the same, all one uniform product. Shell, B.P. and other brands all come from the same tanks. This explains, by the way, why you can't boycott gas that comes from one country, say Venezula. It's all comingled.
