Pumps' Perplexities

In these days everyone is concerned with gasoline and the price of it...
A few years ago, the History Channel, produced a show for its Modern
Marvels program entitled "Gasoline"...I highly recommend that everyone
watch this episode when it is televised again...It seems that the History
Channel is running it more often lately...
While the program covers the "history" of gasoline and its manufacture,
in great detail, it is the fact that all gasoline is basically the same
which effected me the most...It seems that all gasoline which enters the
pipeline and is transported for a long distance by that method must be
manufactured to the same specifications no matter what "brand name" is
on the refinery...
If oil company "A" deposits 100,000 gallons of "grade 87" into the pipeline
in Texas on Monday, it can take out 100,000 gallons of "grade 87" in
Illinois on Tuesday..."Monday's" deposit of gasoline will not reach Illinois
until Saturday...Therefore "Tuesday's" gasoline withdrawal was refined
by oil company "B"...Same grade and same manufacturing specs...Same gas.
Company "A" can introduce some additives to the "same gas" but
company "B" does it also...And the additives are similar.
Please do not take my word for this...I suggest you watch the television
show and confirm these facts yourself...
