In ancient history, each filing station was supplied by their own refinery -
e.g. Texaco gasoline was produced and distributed by Texaco and so forth. That
still holds true for SOME brands but with the advent of no-name gasoline
stations and the economies of scale, Charlie is spot-on - gasoline at no-name X
is the same gasoline as no-name Y with the biggest difference being price which
is dependent on location.
I don't have many gasoline-powered vehicles these days BUT have started using
ethanol-free gasoline in my Land Rover b/c 43 year old fuel systems can't hold
their alcohol <G>. I haven't filled my lawn equipment lately but plan to make
the switch to that as well especially since that equipment tends to sit for
long periods of time between uses.
In the racecar, I used 93 octane ethanol-added b/c I wanted the octane. I
could go to 100 octane BUT the price is almost double and, as noted, the
benefits are minimal unless the computer is tuned for 100 octane. For 99% of
street cars, anything over 93 octane is a waste of money - there are a few cars
that can benefit but very few.

Here where I live I get a kick out of people swearing by a particular brand
of gasoline or condemning another.
What most of them do not realize is that ALL the gas (with one exception)
comes from the SAME local distribution tank farm on the other side of town.
I have passed by there and seen tankers with various brand names on them
filling up. Since there are only a couple of big tanks at this facility
there is no way the base gas is different.
Not sure what additives are being added when each tanker fills up but there
are not a lot of big tanks so the chemical additives cannot vary that much
either.
At the retail level the local Sunoco stations still offer 93 octane.
Personally in more modern vehicles higher octane is a waste of 30 cents more
per gallon for me.
In my older VWs I have started using Ethanol-free 87 Octane. It is a lot
more expensive at the only place that sells it near where I live but I do
not drive them as much and the gas mileage is better.
This place does a Booming business from old vehicle owners, motorcycle
owners and lawn care companies.
On a towing trip last summer I filled up my pickup with ethanol-free gas in
Virginia. Performance was better and MPG increased 10%+.
On that trip the ethanol-free gas was 40 cents/gal cheaper than my gas at
home with ethanol. I'm guessing the Pennsylvania state gas taxes played a
big part in the price difference.
I also use the ethanol-free gas in my lawn mower and small engine devices
here at home.
