You know how some people with cars put hi octane in, thinking it is going to
get them better performance? Waste of money, since no more power is
produced, without re-tuning the engine, but no problem.

Unless it's one of those engines that has computer controlled
individual cylinder timing using a knock sensor. Those things will
retard the timing if knocking is sensed, and advance the timing as far
as possible when knocking is not sensed.

I remember seeing a Saab with such a system being dynoed using regular
first and then high test. The engine gained some power, although I
don't remember the exact figures. I just remember that it did gain
some.

With engines that do not have constantly adjusting timing, you are
correct, using high octane gas won't make any difference in power.

I have been fueling for years with plastic containers. As the first link
(from FAA) recommends, the fuel container nozzle is inserted into the tank
opening before fuel begins to flow, and the container nozzle continues
contact with the aircraft fuel tank throughout the process. I have never
seen a spark or had a fire, but always keep a halon fire extinguisher handy.
The aircraft is, of course, never refueled in the hangar. It is always out
on the ramp away from buildings, vehicles, and other aircraft.

That's not to say that a grounding wire should not be used.

Given the fact that most airplane engines don't even have the most basic
advantage, even of vacuum advance, I didn't think that was a very important
factor. g

Good point, but most will only advance within a certain set of parameters.
I doubt if it would be enough to take advantage as much as if you changed it
manually.

Life rules state that there are always exceptions to the rules, right?
