Fuel Pumps @ Stations

 I read this on another forum and thought it interesting. Any thoughts on
this?:

"Buy your fuel from a station that has a hose for each grade of fuel. This
came up several years ago on another forum and the person who replied to a
simmular question was a fuel pump repairman & installer of new fuel systems.
He said at a pump with just one hose for all three grades, if the guy in
front of you bought reg. unleaded you would get at least a gallon and a half
of standard unleaded before the premium started flowing. If you pull up in a
vette or lexus 1 1/2 gal. of regular unleaded isint going to lower your
overall octain rating much, but on a harley where we are just putting in a
few gallons that 1 1/2 gal. of 87 octain lowers the average quite a bit. Do
this several times in a row and your overall average octain is much lower
than what is called for. The switch that changes fuel grade to the single
hose is below ground level, and to maintain pressure the size of the pipe
carrying the fuel gets smaller at every joint, and you are paying the
premium price the minute the fuel starts flowing. They now have anti-siphon
device that when the hose shuts off nothing but the gas in the handle will
run out. Not like back in the 70s when you could shut it off at the pump and
hold the nozzle down & drain the hose & the next guy in line had to pay to
fill the hose. I told all my riding buddies here in the Georgetown Texas
area about this and we all could tell that mileage & performance was better
with the multi hose gas fillup than the single hose. Sometimes when
traveling in a group we all stop in the same place you cant allways get the
pump with a hose for each grade and over several fillups like this my ultra
pings, has bad performance, & gets crappy mileage. Sorry reply is so long
not any way to say all this without being long winded."

  They're restricted by law on the volume that remains in the hose/system -
just so this can't happen . I sometimes use a multi-hose station , sometimes
a one-hose station , and I've never seen any difference . My bike will ping
lightly on take-off from a stop after a hard run when it's hot out , I'd
notice if the fuel was lower in octane ...

It's bullshit. That hose holds about a cup of fuel. I have drained a
bunch of them.

I strive to buy my fuel at stations that provide individual nozzles for each
grade, the Vrod & Ultra-SE-2 both demand the highest octane possible, the
rare occasion that I m not able to get the best delivery method, I then look
at each pump to see which grade was last pumped from it, if it was crap I
skip it, also I get in line behind a Vette or a other high performance
persnickity vehicle, chances are you will be good to get the GOOD STUFF when
you pull up.

In may area the only stations that still have individual nozzles are HESS &
select few Shell Stations.
